✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Unplug dryer and remove front panel
- Locate the power cord at the back of the dryer, typically exiting from the lower right or center rear section.
- Pull the dryer away from the wall approximately 2-3 feet to access the rear completely.
- Grasp the plug firmly where it connects to the wall outlet and pull straight out with steady pressure.
- Verify power is disconnected by attempting to turn the dryer timer knob – the control panel should remain completely dark and unresponsive.
- Open the dryer door fully and locate 2 Phillips-head screws inside the door opening – one on the left side and one on the right side, positioned approximately 2 inches down from the top edge of the door frame.
- Remove both screws using a Phillips #2 screwdriver and set them aside in a container.
- Close the dryer door completely.
- Locate the lint screen housing at the top front of the dryer and pull the lint screen straight out.
- Look inside the lint screen cavity and identify 2 Phillips-head screws – one on the left side and one on the right side of the cavity opening.
- Remove both screws using the Phillips #2 screwdriver.
- Grasp the front panel firmly on both left and right edges at waist height.
- Lift the entire front panel upward approximately 1 inch until the bottom edge clears the dryer base clips.
- Pull the panel straight toward you while supporting its weight – the panel weighs approximately 15-20 pounds.
- Set the front panel against a nearby wall or flat surface with the interior side facing up to protect the exterior finish.
- You will now see the drum assembly, belt, motor, and internal components fully exposed from the front.
🔍
🛠️ Step 2: Locate belt switch (monitors drive belt position)
- Position yourself at the rear of the dryer, facing the back panel that you removed in Step 1.
- Look at the lower right section of the dryer’s interior frame, approximately 8 inches up from the bottom and 4 inches from the right edge.
- Identify the belt switch—a small black or white plastic component measuring roughly 1.5 inches long by 0.75 inches wide with a single wire harness connector attached.
- Observe the thin metal actuator arm extending from the switch body, approximately 2 inches in length, angled downward at roughly 45 degrees.
- Trace the wire harness from the belt switch—it runs upward along the right side panel toward the control area, typically a white or brown 2-wire connector.
- Note the switch’s mounting position: it clips or screws into a metal bracket welded to the dryer’s frame, with the actuator arm positioned to contact the drive belt.
- Verify you’ve found the correct component by confirming these features: the actuator arm sits in the path where the drive belt would normally ride, and pressing the actuator arm inward produces a faint clicking sound from the internal contacts.
- Examine the switch mounting—look for either a single Phillips-head screw (typically #2 size) securing it to the bracket, or plastic snap tabs on both sides that lock it in place.
- Check the wire connector for a locking tab on top—this small plastic protrusion (approximately 0.25 inches) must be pressed to disconnect the harness.
- Confirm the part number stamped on the switch body if visible: typically reads “WE4M519” or similar alphanumeric code, verifying this is the belt switch assembly.
🔍
⚙️ Step 3: Inspect drive belt for proper installation
- Locate the drive belt wrapped around the drum – it’s a black rubber belt approximately 1/4 inch wide that should be positioned around the entire circumference of the dryer drum.
- Check the belt’s position on the drum by running your hand along the drum’s outer edge where it meets the belt – the belt should sit centered in the groove or channel that runs around the drum’s middle, approximately 12-14 inches from either the front or back edge of the drum.
- Examine the belt routing pattern by looking at the motor pulley location – find the motor assembly mounted on the bottom right side of the dryer cabinet, approximately 8 inches from the right edge and 4 inches from the back.
- Verify the belt follows this path: wrapped around the drum, looped under the idler pulley (a spring-loaded wheel about 2 inches in diameter located 6 inches to the left of the motor), then wrapped around the motor pulley in a clockwise direction when viewing from the motor shaft end.
- Press down on the belt between the idler pulley and motor pulley – it should have 1/4 to 1/2 inch of give when you apply firm pressure with your thumb.
- Inspect the belt’s ribbed side (the side with grooves) – this textured surface must face toward the drum, making contact with the drum surface, not the smooth side.
- Check for belt twists by following the entire belt path – the belt should lie completely flat with no 180-degree twists or flips anywhere along its route.
- Look at both edges of the belt for fraying, cracks, or glazing (shiny, hardened surface) – a properly installed belt appears matte black with clean, square edges.
- Rotate the drum manually by hand one complete revolution clockwise – the belt should move smoothly without slipping, jumping off the pulleys, or making scraping sounds against the cabinet walls.
🧪
🔩 Step 4: Test belt switch continuity with multimeter
- Locate the belt switch—a small rectangular component measuring approximately 1.5 inches long by 0.75 inches wide, mounted on the blower housing at the bottom rear of the dryer drum cavity.
- Identify the two wire terminals protruding from the top of the belt switch body (GE part number WE4M519).
- Grasp the white wire connector on the left terminal and pull straight up to disconnect it from the switch.
- Grasp the white wire connector on the right terminal and pull straight up to disconnect it.
- Set your digital multimeter to the lowest ohms (Ω) setting, typically 200Ω or the continuity setting (usually marked with a diode symbol).
- Touch the red multimeter probe to the left terminal on the belt switch.
- Touch the black multimeter probe to the right terminal on the belt switch.
- Read the display—the meter should show “O.L.” (open line) or infinite resistance, indicating the switch is open (normal when the belt is present).
- Press down on the white plastic actuator button located on the front face of the belt switch using your index finger until it clicks.
- While holding the button depressed, observe the multimeter display—it should now read 0.0 to 0.5 ohms, indicating closed circuit and proper switch function.
- Release the button and verify the display returns to “O.L.” or infinite resistance.
- If readings show continuity (0-0.5 ohms) without pressing the button, the switch is stuck closed and requires replacement.
- If readings show “O.L.” both with and without pressing the button, the switch contacts are faulty and require replacement.
- If readings match the expected values (open when released, closed when pressed), the belt switch is functioning correctly.
🧪
📋 Step 5: Switch should show continuity when belt is properly positioned
- Locate the belt switch on the left side of the dryer cabinet, approximately 8 inches down from the top edge and 3 inches back from the front panel edge. It’s a small white plastic housing with two wire terminals.
- Remove both wire connectors from the belt switch terminals by pulling each connector straight off with your fingers. Note that one wire is typically orange and one is white.
- Set your multimeter to the continuity setting (often marked with a diode symbol or sound wave icon) or the lowest ohms setting (usually 200Ω or RX1).
- Touch one multimeter probe to each of the two metal terminals on the belt switch itself (not the wires).
- Observe the multimeter reading. With the drum belt properly positioned around the drum and tensioned by the idler pulley, the switch actuator arm should be pressed inward, and the meter should read 0 ohms or emit a continuous beep, indicating continuity.
- If no continuity is present, manually press the small white plastic actuator arm that protrudes from the switch body approximately 1/4 inch inward using your finger. The multimeter should now show continuity.
- Release the actuator arm and verify it springs back out approximately 1/4 inch from the switch body.
- Check that the belt is making contact with and depressing the actuator arm. The belt should sit against the arm when properly tensioned, keeping it pressed inward.
- If the switch shows continuity when manually pressed but not when released to the belt, recheck your belt routing around the idler pulley and motor pulley. The belt tension may be insufficient to activate the switch.
- Replace the belt switch (part number WE04X10059) if it fails to show continuity when the actuator arm is pressed inward, or if the actuator arm doesn’t spring back when released.
🔍
✅ Step 6: If switch fails to activate, check belt routing
- Locate the drive motor at the bottom left front of the dryer drum cavity, approximately 8 inches from the left edge and 3 inches from the front panel.
- Identify the drum belt – a flat, ribbed rubber belt approximately 92 inches long and 1/4 inch wide that wraps around the drum, motor pulley, and idler pulley.
- Trace the belt path starting from the drum: the belt should wrap around the entire drum circumference with the ribbed side facing inward against the metal drum surface.
- Follow the belt as it exits the drum at the bottom rear, approximately 2 inches from the right side of the drum opening.
- Verify the belt wraps under the idler pulley (a spring-loaded wheel approximately 2 inches in diameter, located at the bottom right rear, 4 inches from the back panel).
- Confirm the belt continues from the idler pulley to wrap around the motor pulley in a clockwise direction when viewed from the motor shaft end.
- Check that the belt forms a complete “W” pattern: drum → idler pulley → motor pulley.
- Examine the door switch actuator arm (white plastic lever, 3 inches long) located on the door strike mechanism at the top right of the drum opening.
- Manually rotate the drum clockwise one full revolution while watching the actuator arm – it should move freely without belt interference.
- Look for belt misalignment where the belt crosses near the door switch area – the belt should pass at least 1 inch below the actuator arm’s lowest position.
- If the belt touches or restricts the actuator arm movement, remove the belt completely by pulling it off the motor pulley first, then the idler pulley, then lifting it off the drum.
- Reinstall the belt following the correct routing pattern: place it around the drum first (ribs inward), loop under the idler pulley, then stretch it onto the motor pulley while pushing the idler pulley toward the motor to create slack.
✔️
🔍 Step 7: Verify belt is not broken or excessively worn
- Locate the drum belt wrapped around the drum – it’s a flat, ribbed rubber belt approximately 3/8 inch wide running along the entire circumference of the drum at the rear section.
- Grip the belt with your fingers at the bottom center of the drum and pull downward with moderate pressure to expose a 6-8 inch section for inspection.
- Run your fingers along the exposed section feeling for any breaks, splits, or separated sections – an intact belt will be continuous with no gaps.
- Examine the inner ribbed surface of the belt (the side touching the drum) – count the ribs which should be evenly spaced approximately 1/8 inch apart running the length of the belt.
- Check for missing chunks or torn sections along the edges – the belt edges should be smooth and uniform along the entire width.
- Look for glazing or shiny spots on the ribbed surface – a properly functioning belt has a matte black finish, while excessive wear creates glossy areas.
- Measure the belt width at three different points around the drum using a ruler – the width should be consistent at 5/16 inch, with no variation exceeding 1/16 inch indicating stretching.
- Check for fraying fabric cords visible along the edges or through cracks – these reinforcement cords should not be exposed in a good belt.
- Rotate the drum by hand counterclockwise one full revolution while maintaining light tension on the belt to inspect the entire length.
- If you find any cracks wider than 1/32 inch, more than 3 glazed spots larger than a quarter, exposed cords, or the belt stretches more than 1 inch when pulled, replacement is required using part number WE12M29.
- If the belt passes all inspections with no damage visible, proceed to the next step.
🧪
💡 Step 8: Test switch operation manually
- Locate the door switch you’ve just installed or reconnected – it sits in the door frame opening at the top right corner, approximately 2 inches from the right edge and 1 inch down from the top of the cabinet opening.
- Identify the white plastic actuator arm extending from the switch body – this arm should protrude approximately 1/2 inch outward when the door is open.
- Press the actuator arm inward using your index finger with firm, steady pressure until it depresses fully (approximately 1/2 inch travel distance) – you should feel a distinct click at the end of travel.
- Release the actuator arm and observe it spring back to its extended position within 1 second – if it doesn’t return immediately, the switch is defective.
- Repeat the press-and-release action 5 times in succession, listening for a consistent clicking sound on each depression – inconsistent clicks indicate internal contact problems.
- Set your multimeter to continuity mode (the symbol showing sound waves or a diode).
- Touch one multimeter probe to each of the two metal terminals on the back of the switch where the wire connectors attach.
- Press the switch actuator arm inward while holding both probes on the terminals – the multimeter should emit a continuous beep and display “0” or close to zero ohms, indicating closed contacts.
- Release the switch actuator arm while maintaining probe contact – the multimeter beep should stop and display “OL” (open line) or infinite resistance, indicating open contacts.
- Verify the switch operates in the opposite direction by checking that open becomes closed (no beep to beep) when you depress it, and closed becomes open (beep to no beep) when you release it – this confirms proper switching action.
- Reconnect the wire harness connector to the switch terminals by pushing until you hear an audible click – successful connection requires no visible gap between connector housing and switch body.
✅
⚡ Step 9: If switch is faulty, remove and replace
- Grip the wire harness connector attached to the door switch with your thumb and forefinger, pressing the locking tab on top of the connector body with your thumb.
- Pull the connector straight back away from the switch terminals while maintaining pressure on the locking tab until it separates completely (requires approximately 3-5 pounds of pull force).
- Locate the single mounting screw at the top center of the switch body, positioned directly above the switch plunger.
- Use a 1/4-inch nut driver to rotate the mounting screw counterclockwise 8-10 full turns until the screw releases completely from the switch mounting bracket.
- Pull the switch body forward and away from the dryer frame approximately 2 inches until it clears the rectangular mounting slot.
- Set the old switch aside and retrieve your replacement door switch (GE part number WE4M519).
- Align the rectangular mounting tab on the back of the new switch with the corresponding slot in the dryer frame, oriented so the wire terminals face outward toward you.
- Push the new switch body into the mounting slot until it sits flush against the dryer frame with no gaps visible.
- Insert the mounting screw through the hole at the top of the switch body, threading it clockwise by hand for 3-4 turns until finger-tight.
- Use the 1/4-inch nut driver to tighten the mounting screw an additional 2-3 full turns until snug (do not overtighten as the plastic switch housing can crack).
- Align the wire harness connector with the two blade terminals on the new switch, matching the connector’s rectangular shape to the terminal orientation.
- Push the connector firmly onto the switch terminals until you hear and feel a distinct click, indicating the locking tab has engaged (requires 5-8 pounds of pressure).
- Verify the connection by gently pulling on the wire harness; the connector should remain firmly attached without movement.
✅
🎯 Step 10: Reinstall belt switch and verify proper operation
- Locate the belt switch mounting bracket on the right side of the blower housing, positioned 3 inches below the drum support and 2 inches from the front edge of the housing.
- Position the belt switch (part number WE4M519) so the plastic actuator arm extends toward the idler pulley location and the white wire connector faces the right side panel.
- Insert the single mounting screw (5/16-inch hex head) through the bracket hole and thread it into the blower housing mounting point.
- Tighten the mounting screw using a 5/16-inch nut driver, turning clockwise until the switch bracket sits flush against the housing (approximately 8-10 inch-pounds of resistance).
- Locate the white 2-wire connector from the main wiring harness, positioned 4 inches above the belt switch location along the right side panel.
- Align the belt switch’s white connector with the harness connector, matching the tab on one side with the slot on the other.
- Push the connectors together firmly until you hear and feel a distinct click, indicating full engagement.
- Press the belt switch actuator arm inward toward the housing using your thumb – you should hear a clicking sound indicating the switch is functioning.
- Release the actuator arm and verify it springs back to the extended position, approximately 1/2 inch from the housing.
- Rotate the drum by hand through 2 complete revolutions while watching the idler pulley contact the belt switch actuator arm – the arm should depress and release with each rotation.
- Use a multimeter set to continuity mode and touch the probes to each terminal on the belt switch connector while manually pressing the actuator arm – the meter should beep when the arm is pressed and go silent when released, confirming proper switch operation.

🔧 Step 11: Test dryer operation
- Verify the dryer is plugged into the 240V electrical outlet at the wall behind the unit.
- Turn on the gas supply valve (if gas model) located on the supply line behind the dryer – rotate the valve handle until it’s parallel with the gas pipe.
- Open the dryer door and inspect the drum interior to confirm no tools, screws, or parts remain inside from your repair.
- Close the dryer door firmly until you hear the door latch click into place.
- Turn the cycle selector knob clockwise to the “Timed Dry” setting (located on the control panel at the top right).
- Set the temperature selector knob to “Medium Heat” (center position on the temperature dial).
- Press the “Start” button (white rectangular button at the top center of the control panel).
- Listen for the motor to engage within 2-3 seconds – you’ll hear a low humming sound as the blower motor starts.
- Confirm the drum begins rotating clockwise when viewed from the front within 5 seconds of pressing start.
- Open the dryer door briefly to stop the cycle, then close it and press “Start” again to verify the door switch is functioning – the drum should stop when opened and restart when closed and restarted.
- Let the dryer run for 3 minutes, then open the exhaust vent hood outside your home (typically 4-inch diameter vent) and feel for strong, steady airflow.
- Return to the dryer and feel the air temperature inside the drum after 5 minutes of operation – it should feel warm to hot (approximately 130-150°F).
- Press the “Start” button to pause the cycle, rotate the cycle selector to “Air Fluff” (no heat setting), and restart to verify the no-heat cycle operates with drum rotation and airflow but no heating element activation.
- Stop the dryer and run one final complete 10-minute cycle on “Timed Dry/Medium Heat” to confirm all functions work continuously without unusual noises, vibrations, or burning smells.

🔩 Step 4: Test belt switch continuity with multimeter
- Locate the belt switch—a small rectangular component measuring approximately 1.5 inches long by 0.75 inches wide, mounted on the blower housing at the bottom rear of the dryer drum cavity.
- Identify the two wire terminals protruding from the top of the belt switch body (GE part number WE4M519).
- Grasp the white wire connector on the left terminal and pull straight up to disconnect it from the switch.
- Grasp the white wire connector on the right terminal and pull straight up to disconnect it.
- Set your digital multimeter to the lowest ohms (Ω) setting, typically 200Ω or the continuity setting (usually marked with a diode symbol).
- Touch the red multimeter probe to the left terminal on the belt switch.
- Touch the black multimeter probe to the right terminal on the belt switch.
- Read the display—the meter should show “O.L.” (open line) or infinite resistance, indicating the switch is open (normal when the belt is present).
- Press down on the white plastic actuator button located on the front face of the belt switch using your index finger until it clicks.
- While holding the button depressed, observe the multimeter display—it should now read 0.0 to 0.5 ohms, indicating closed circuit and proper switch function.
- Release the button and verify the display returns to “O.L.” or infinite resistance.
- If readings show continuity (0-0.5 ohms) without pressing the button, the switch is stuck closed and requires replacement.
- If readings show “O.L.” both with and without pressing the button, the switch contacts are faulty and require replacement.
- If readings match the expected values (open when released, closed when pressed), the belt switch is functioning correctly.
🧪
📋 Step 5: Switch should show continuity when belt is properly positioned
- Locate the belt switch on the left side of the dryer cabinet, approximately 8 inches down from the top edge and 3 inches back from the front panel edge. It’s a small white plastic housing with two wire terminals.
- Remove both wire connectors from the belt switch terminals by pulling each connector straight off with your fingers. Note that one wire is typically orange and one is white.
- Set your multimeter to the continuity setting (often marked with a diode symbol or sound wave icon) or the lowest ohms setting (usually 200Ω or RX1).
- Touch one multimeter probe to each of the two metal terminals on the belt switch itself (not the wires).
- Observe the multimeter reading. With the drum belt properly positioned around the drum and tensioned by the idler pulley, the switch actuator arm should be pressed inward, and the meter should read 0 ohms or emit a continuous beep, indicating continuity.
- If no continuity is present, manually press the small white plastic actuator arm that protrudes from the switch body approximately 1/4 inch inward using your finger. The multimeter should now show continuity.
- Release the actuator arm and verify it springs back out approximately 1/4 inch from the switch body.
- Check that the belt is making contact with and depressing the actuator arm. The belt should sit against the arm when properly tensioned, keeping it pressed inward.
- If the switch shows continuity when manually pressed but not when released to the belt, recheck your belt routing around the idler pulley and motor pulley. The belt tension may be insufficient to activate the switch.
- Replace the belt switch (part number WE04X10059) if it fails to show continuity when the actuator arm is pressed inward, or if the actuator arm doesn’t spring back when released.
🔍
✅ Step 6: If switch fails to activate, check belt routing
- Locate the drive motor at the bottom left front of the dryer drum cavity, approximately 8 inches from the left edge and 3 inches from the front panel.
- Identify the drum belt – a flat, ribbed rubber belt approximately 92 inches long and 1/4 inch wide that wraps around the drum, motor pulley, and idler pulley.
- Trace the belt path starting from the drum: the belt should wrap around the entire drum circumference with the ribbed side facing inward against the metal drum surface.
- Follow the belt as it exits the drum at the bottom rear, approximately 2 inches from the right side of the drum opening.
- Verify the belt wraps under the idler pulley (a spring-loaded wheel approximately 2 inches in diameter, located at the bottom right rear, 4 inches from the back panel).
- Confirm the belt continues from the idler pulley to wrap around the motor pulley in a clockwise direction when viewed from the motor shaft end.
- Check that the belt forms a complete “W” pattern: drum → idler pulley → motor pulley.
- Examine the door switch actuator arm (white plastic lever, 3 inches long) located on the door strike mechanism at the top right of the drum opening.
- Manually rotate the drum clockwise one full revolution while watching the actuator arm – it should move freely without belt interference.
- Look for belt misalignment where the belt crosses near the door switch area – the belt should pass at least 1 inch below the actuator arm’s lowest position.
- If the belt touches or restricts the actuator arm movement, remove the belt completely by pulling it off the motor pulley first, then the idler pulley, then lifting it off the drum.
- Reinstall the belt following the correct routing pattern: place it around the drum first (ribs inward), loop under the idler pulley, then stretch it onto the motor pulley while pushing the idler pulley toward the motor to create slack.
✔️
🔍 Step 7: Verify belt is not broken or excessively worn
- Locate the drum belt wrapped around the drum – it’s a flat, ribbed rubber belt approximately 3/8 inch wide running along the entire circumference of the drum at the rear section.
- Grip the belt with your fingers at the bottom center of the drum and pull downward with moderate pressure to expose a 6-8 inch section for inspection.
- Run your fingers along the exposed section feeling for any breaks, splits, or separated sections – an intact belt will be continuous with no gaps.
- Examine the inner ribbed surface of the belt (the side touching the drum) – count the ribs which should be evenly spaced approximately 1/8 inch apart running the length of the belt.
- Check for missing chunks or torn sections along the edges – the belt edges should be smooth and uniform along the entire width.
- Look for glazing or shiny spots on the ribbed surface – a properly functioning belt has a matte black finish, while excessive wear creates glossy areas.
- Measure the belt width at three different points around the drum using a ruler – the width should be consistent at 5/16 inch, with no variation exceeding 1/16 inch indicating stretching.
- Check for fraying fabric cords visible along the edges or through cracks – these reinforcement cords should not be exposed in a good belt.
- Rotate the drum by hand counterclockwise one full revolution while maintaining light tension on the belt to inspect the entire length.
- If you find any cracks wider than 1/32 inch, more than 3 glazed spots larger than a quarter, exposed cords, or the belt stretches more than 1 inch when pulled, replacement is required using part number WE12M29.
- If the belt passes all inspections with no damage visible, proceed to the next step.
🧪
💡 Step 8: Test switch operation manually
- Locate the door switch you’ve just installed or reconnected – it sits in the door frame opening at the top right corner, approximately 2 inches from the right edge and 1 inch down from the top of the cabinet opening.
- Identify the white plastic actuator arm extending from the switch body – this arm should protrude approximately 1/2 inch outward when the door is open.
- Press the actuator arm inward using your index finger with firm, steady pressure until it depresses fully (approximately 1/2 inch travel distance) – you should feel a distinct click at the end of travel.
- Release the actuator arm and observe it spring back to its extended position within 1 second – if it doesn’t return immediately, the switch is defective.
- Repeat the press-and-release action 5 times in succession, listening for a consistent clicking sound on each depression – inconsistent clicks indicate internal contact problems.
- Set your multimeter to continuity mode (the symbol showing sound waves or a diode).
- Touch one multimeter probe to each of the two metal terminals on the back of the switch where the wire connectors attach.
- Press the switch actuator arm inward while holding both probes on the terminals – the multimeter should emit a continuous beep and display “0” or close to zero ohms, indicating closed contacts.
- Release the switch actuator arm while maintaining probe contact – the multimeter beep should stop and display “OL” (open line) or infinite resistance, indicating open contacts.
- Verify the switch operates in the opposite direction by checking that open becomes closed (no beep to beep) when you depress it, and closed becomes open (beep to no beep) when you release it – this confirms proper switching action.
- Reconnect the wire harness connector to the switch terminals by pushing until you hear an audible click – successful connection requires no visible gap between connector housing and switch body.
✅
⚡ Step 9: If switch is faulty, remove and replace
- Grip the wire harness connector attached to the door switch with your thumb and forefinger, pressing the locking tab on top of the connector body with your thumb.
- Pull the connector straight back away from the switch terminals while maintaining pressure on the locking tab until it separates completely (requires approximately 3-5 pounds of pull force).
- Locate the single mounting screw at the top center of the switch body, positioned directly above the switch plunger.
- Use a 1/4-inch nut driver to rotate the mounting screw counterclockwise 8-10 full turns until the screw releases completely from the switch mounting bracket.
- Pull the switch body forward and away from the dryer frame approximately 2 inches until it clears the rectangular mounting slot.
- Set the old switch aside and retrieve your replacement door switch (GE part number WE4M519).
- Align the rectangular mounting tab on the back of the new switch with the corresponding slot in the dryer frame, oriented so the wire terminals face outward toward you.
- Push the new switch body into the mounting slot until it sits flush against the dryer frame with no gaps visible.
- Insert the mounting screw through the hole at the top of the switch body, threading it clockwise by hand for 3-4 turns until finger-tight.
- Use the 1/4-inch nut driver to tighten the mounting screw an additional 2-3 full turns until snug (do not overtighten as the plastic switch housing can crack).
- Align the wire harness connector with the two blade terminals on the new switch, matching the connector’s rectangular shape to the terminal orientation.
- Push the connector firmly onto the switch terminals until you hear and feel a distinct click, indicating the locking tab has engaged (requires 5-8 pounds of pressure).
- Verify the connection by gently pulling on the wire harness; the connector should remain firmly attached without movement.

- Confirm the drum begins rotating clockwise when viewed from the front within 5 seconds of pressing start.
- Open the dryer door briefly to stop the cycle, then close it and press “Start” again to verify the door switch is functioning – the drum should stop when opened and restart when closed and restarted.
- Let the dryer run for 3 minutes, then open the exhaust vent hood outside your home (typically 4-inch diameter vent) and feel for strong, steady airflow.
- Return to the dryer and feel the air temperature inside the drum after 5 minutes of operation – it should feel warm to hot (approximately 130-150°F).
- Press the “Start” button to pause the cycle, rotate the cycle selector to “Air Fluff” (no heat setting), and restart to verify the no-heat cycle operates with drum rotation and airflow but no heating element activation.
- Stop the dryer and run one final complete 10-minute cycle on “Timed Dry/Medium Heat” to confirm all functions work continuously without unusual noises, vibrations, or burning smells.

🎯 Step 10: Reinstall belt switch and verify proper operation
- Locate the belt switch mounting bracket on the right side of the blower housing, positioned 3 inches below the drum support and 2 inches from the front edge of the housing.
- Position the belt switch (part number WE4M519) so the plastic actuator arm extends toward the idler pulley location and the white wire connector faces the right side panel.
- Insert the single mounting screw (5/16-inch hex head) through the bracket hole and thread it into the blower housing mounting point.
- Tighten the mounting screw using a 5/16-inch nut driver, turning clockwise until the switch bracket sits flush against the housing (approximately 8-10 inch-pounds of resistance).
- Locate the white 2-wire connector from the main wiring harness, positioned 4 inches above the belt switch location along the right side panel.
- Align the belt switch’s white connector with the harness connector, matching the tab on one side with the slot on the other.
- Push the connectors together firmly until you hear and feel a distinct click, indicating full engagement.
- Press the belt switch actuator arm inward toward the housing using your thumb – you should hear a clicking sound indicating the switch is functioning.
- Release the actuator arm and verify it springs back to the extended position, approximately 1/2 inch from the housing.
- Rotate the drum by hand through 2 complete revolutions while watching the idler pulley contact the belt switch actuator arm – the arm should depress and release with each rotation.
- Use a multimeter set to continuity mode and touch the probes to each terminal on the belt switch connector while manually pressing the actuator arm – the meter should beep when the arm is pressed and go silent when released, confirming proper switch operation.

🔧 Step 11: Test dryer operation
- Verify the dryer is plugged into the 240V electrical outlet at the wall behind the unit.
- Turn on the gas supply valve (if gas model) located on the supply line behind the dryer – rotate the valve handle until it’s parallel with the gas pipe.
- Open the dryer door and inspect the drum interior to confirm no tools, screws, or parts remain inside from your repair.
- Close the dryer door firmly until you hear the door latch click into place.
- Turn the cycle selector knob clockwise to the “Timed Dry” setting (located on the control panel at the top right).
- Set the temperature selector knob to “Medium Heat” (center position on the temperature dial).
- Press the “Start” button (white rectangular button at the top center of the control panel).
- Listen for the motor to engage within 2-3 seconds – you’ll hear a low humming sound as the blower motor starts.
- Confirm the drum begins rotating clockwise when viewed from the front within 5 seconds of pressing start.
- Open the dryer door briefly to stop the cycle, then close it and press “Start” again to verify the door switch is functioning – the drum should stop when opened and restart when closed and restarted.
- Let the dryer run for 3 minutes, then open the exhaust vent hood outside your home (typically 4-inch diameter vent) and feel for strong, steady airflow.
- Return to the dryer and feel the air temperature inside the drum after 5 minutes of operation – it should feel warm to hot (approximately 130-150°F).
