✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Unplug the dryer and remove lint filter
- Locate the power cord at the rear of the dryer, approximately 4-6 inches from the bottom and centered along the back panel.
- Trace the power cord from the dryer to the wall outlet (240V outlet with either 3 or 4 prongs).
- Grasp the plug body firmly where it meets the outlet, not the cord itself.
- Pull the plug straight out from the wall outlet using steady pressure until completely disconnected.
- Move the loose power cord to the side or drape it over the top of the dryer so it’s out of your work area.
- Stand directly in front of the dryer door.
- Look at the door opening – the lint filter is located at the top of the door opening, centered horizontally.
- Identify the lint filter handle, which is a recessed plastic tab approximately 1 inch wide, positioned at the top center of the lint screen.
- Place your fingers on the lint filter handle and pull straight up with moderate force.
- The lint filter will slide vertically upward out of its housing – continue pulling until the entire screen (approximately 14 inches long) is completely removed from the dryer.
- Set the lint filter aside on a clean, flat surface.
- Look into the now-empty lint filter cavity – you should see a rectangular opening approximately 2 inches wide and 13 inches deep leading into the dryer drum area.
- Verify you have clear access to the lint filter housing, as you’ll need this opening accessible for upcoming repair steps.
🔍
🛠️ Step 2: Inspect lint filter for damage or excessive buildup
- Open the dryer door fully by pulling it toward you until it stops at approximately 90 degrees.
- Locate the lint filter housing at the top front of the drum opening, centered horizontally, recessed approximately 1 inch into the cabinet.
- Grip the lint filter handle (a vertical plastic tab measuring approximately 1 inch wide) with your thumb and index finger.
- Pull the lint filter straight upward with steady pressure until it slides completely out of its housing slot, traveling approximately 10-11 inches vertically.
- Hold the filter under direct light from a ceiling fixture or flashlight positioned 12-18 inches away.
- Examine the mesh screen surface for tears, holes, or separated seams by running your fingertip across the entire surface in a grid pattern, covering every 2-inch section.
- Look for fabric fibers that have melted into the mesh, appearing as shiny, hardened spots or a waxy coating that gives the screen a glazed appearance.
- Check the plastic frame edges for cracks longer than 1/4 inch, particularly at the four corners where stress concentrates.
- Run the filter under warm tap water for 30 seconds, holding it at a 45-degree angle under the stream.
- Observe if water beads up on the surface or passes through immediately—beading indicates fabric softener residue buildup blocking airflow.
- If water beads, wet a soft-bristle brush (like a toothbrush) and apply 3-4 drops of liquid dish soap to the mesh.
- Scrub both sides of the mesh in circular motions for 60 seconds, working the bristles through the screen openings.
- Rinse under warm running water for 45 seconds until soap suds disappear completely and water flows freely through all sections of the mesh.
- Shake the filter 5-6 times with downward snapping motions to remove excess water droplets.
🧹
⚙️ Step 3: Clean lint filter thoroughly with warm water and mild detergent
- Grip the lint filter handle located inside the dryer door opening at the bottom center, approximately 2 inches below the door seal.
- Pull the lint filter straight up and out of its housing slot until completely removed (the filter measures approximately 20 inches long).
- Hold the filter over a trash can and use your hand to remove the visible lint layer by wiping from top to bottom in one smooth motion.
- Walk to your kitchen or utility sink and turn on the faucet to warm water (approximately 100-110°F).
- Hold the lint filter under the running water with the screen facing up, starting at one end and moving to the other for 10-15 seconds.
- Flip the filter over and rinse the opposite side for another 10-15 seconds.
- Apply 3-4 drops of liquid dish detergent (Dawn, Palmolive, or similar) directly onto the mesh screen surface.
- Use a soft-bristled nylon brush or old toothbrush to scrub both sides of the mesh screen in circular motions, covering all 20 inches of screen area.
- Pay extra attention to the mesh edges where fabric softener residue typically accumulates—you’ll see white or translucent buildup in these areas.
- Rinse both sides of the filter under warm running water for 30 seconds until all soap suds disappear and water flows freely through the mesh.
- Hold the filter up to a light source and look through the mesh—you should see light passing through all sections without dark spots or blocked areas.
- Shake the filter 4-5 times over the sink to remove excess water droplets.
- Place the filter on a clean towel and allow it to air dry completely for 20-30 minutes before reinstalling (the mesh should feel dry to the touch with no water droplets visible).
🔍
🔩 Step 4: Check exhaust vent connection at the back of the dryer
- Locate the exhaust vent outlet on the rear panel of the dryer, positioned center-left, approximately 8 inches from the left edge and 12 inches from the bottom.
- Identify the metal duct connector (typically 4 inches in diameter) attached to this exhaust outlet.
- Examine the connection type – you’ll see either a metal clamp with a screw head or a snap-on plastic fitting securing the vent hose to the dryer outlet.
- If a metal clamp is present, use a 5/16-inch nut driver or flathead screwdriver to loosen the clamp screw by turning counterclockwise 3-4 complete rotations until the clamp moves freely.
- Slide the metal clamp away from the connection point, moving it 2-3 inches down the flexible vent hose.
- Grip the flexible vent hose at the connection point and pull straight back with steady pressure to detach it from the dryer’s exhaust outlet.
- Look inside the dryer’s exhaust outlet opening – you should see a clear, unobstructed circular opening leading into the blower housing.
- Insert your fingers or a flashlight into the outlet opening and feel/look for lint buildup, which appears as gray, fibrous material coating the interior walls.
- Check the flexible vent hose end you just removed – the interior should be visible and relatively clean with minimal lint accumulation (less than 1/8-inch coating).
- Verify the exhaust outlet rim has no cracks, dents, or damage that would prevent an airtight seal.
- Reconnect the flexible vent hose by pushing it onto the exhaust outlet until it overlaps by at least 2 inches.
- Reposition the metal clamp over the overlapped section, centered 1 inch from the dryer outlet edge.
- Tighten the clamp screw clockwise until snug – the hose should not rotate or pull off when tugged with moderate force.
🔌
đź“‹ Step 5: Disconnect exhaust vent and inspect for lint accumulation
- Locate the exhaust vent connection at the rear of the dryer, approximately 4 inches from the bottom and centered horizontally on the back panel.
- Identify the metal clamp securing the vent hose to the dryer’s exhaust port—this is typically a 4-inch diameter screw-type clamp or spring clamp.
- If you have a screw-type clamp, use a 5/16-inch nut driver or flat-head screwdriver to turn the screw counterclockwise 3-4 full rotations until the clamp loosens enough to slide.
- If you have a spring clamp, squeeze the two tabs together using slip-joint pliers and slide the clamp 2-3 inches away from the connection point down the flexible vent hose.
- Grip the flexible vent hose with both hands and pull straight back away from the dryer exhaust port with steady pressure—it should slide off after moving 1-2 inches.
- Set the disconnected vent hose on the floor or drape it over the dryer top to keep it out of your work area.
- Look into the dryer’s exhaust port (the 4-inch circular opening on the back panel) and visually inspect for lint buildup along the interior walls.
- Insert a flashlight into the exhaust port opening to illuminate the transition duct that runs from the blower housing to this exit point.
- Use a dryer vent brush (18-24 inch flexible rod with bristles) and insert it fully into the exhaust port, rotating clockwise while pushing inward to dislodge accumulated lint.
- Pull the brush out while continuing to rotate, bringing lint debris with it—repeat this insertion and extraction 3-4 times until minimal lint appears on the brush.
- Inspect the flexible vent hose you removed by looking through one end toward a light source—you should see light passing through if the hose is clear.
- If the hose appears blocked, replace it with a new 4-inch diameter semi-rigid aluminum duct rather than attempting to clean heavily clogged flexible hose.
🧹
âś… Step 6: Use a vent cleaning brush to remove all lint from exhaust duct
- Insert a flexible dryer vent cleaning brush (minimum 10 feet long with 4-inch diameter bristles) into the exhaust duct opening at the back of the dryer where you disconnected the vent hose in the previous step.
- Push the brush forward into the duct using a clockwise rotation motion, turning the handle 2-3 full rotations for every 6 inches of forward progress.
- Continue pushing and rotating until you reach the exterior vent termination point (typically 5-25 feet depending on your installation) or until you feel firm resistance indicating you’ve reached the vent hood outside.
- Pull the brush back toward you while maintaining the clockwise rotation, using the same 2-3 rotations per 6 inches of movement.
- Remove the brush completely and clear the accumulated lint from the bristles by hand, collecting it in a trash bag.
- Repeat steps 1-5 a total of 3 times to ensure thorough cleaning, as the first pass loosens lint and subsequent passes remove it.
- Go outside to your exterior vent hood (typically mounted on an exterior wall or roof) and open the vent flap manually by lifting or pushing it upward.
- Insert the brush from the exterior opening and push inward 2-3 feet while rotating clockwise, then pull back out to capture any remaining lint near the exit point.
- Use a shop vacuum with a 2-inch diameter crevice tool attachment to vacuum out the exhaust duct opening at the back of the dryer, inserting it 12-18 inches into the duct.
- Verify successful cleaning by shining a flashlight into the duct opening—you should see smooth, silver metallic ductwork with no visible lint accumulation on the walls.
🧹
🔍 Step 7: Check exterior vent cap for blockages (birds’ nests, debris)
- Exit your home and walk around the exterior to locate the dryer vent exhaust. This will be a circular or rectangular opening in the wall, typically 4 inches in diameter, usually positioned 12-36 inches above ground level on the side or rear of your house.
- Stand directly in front of the vent cap and visually inspect the louvers or flaps. Look for visible debris such as lint accumulation, leaves, twigs, or nesting materials protruding from the opening.
- Grasp the outer edges of the vent cap hood with both hands. Most caps are friction-fit or held by 2-4 screws. If you see screws, use a Phillips-head screwdriver #2 to remove them by turning counterclockwise.
- Pull the vent cap straight away from the wall once fasteners are removed. Set the cap on the ground with the opening facing up.
- Look inside the vent pipe opening in your wall. Insert your flashlight into the opening and shine it 6-12 inches deep, checking for bird nests (look for circular formations of twigs and grass), lint buildup (appears as gray-white fuzzy material), or other obstructions.
- If you find a bird nest or debris, reach in with your gloved hand and pull the material straight out. For compacted lint, use a dryer vent brush (24-36 inch flexible rod with bristles) and insert it fully into the duct, rotating clockwise while pushing inward, then pull back while continuing rotation.
- Examine the vent cap louvers or flapper door. Pivot the flapper back and forth 5-10 times to verify it moves freely without sticking. Remove any lint stuck to the louvers by wiping with a dry cloth.
- Reattach the vent cap by aligning it with the wall opening and either pressing firmly until secure or reinstalling the 2-4 screws, tightening clockwise until snug.
- The flapper should rest in the closed position but open easily when you blow air toward it from 6 inches away.
✔️
đź’ˇ Step 8: Reconnect vent securely and ensure no kinks or restrictions
- Locate the 4-inch diameter vent outlet port on the rear panel of the dryer, positioned 8 inches from the bottom and centered horizontally.
- Inspect the rigid or semi-rigid metal vent duct (minimum 4-inch diameter) that should still be connected to your wall exhaust port from earlier in the repair.
- Slide the dryer vent clamp (4-inch hose clamp) over the end of the vent duct that will connect to the dryer, positioning it approximately 1 inch from the duct’s end.
- Push the vent duct straight onto the dryer’s exhaust outlet port until the duct covers at least 2 inches of the port’s ribbed surface.
- Position the hose clamp directly over where the duct and port overlap, approximately ½ inch from the outer edge of the port.
- Tighten the clamp using a 5/16-inch nut driver or flat-head screwdriver, turning the screw clockwise until the clamp is snug against the duct—approximately 3-4 full rotations after initial contact.
- Attempt to pull the duct off the port by hand; it should not move more than 1/8 inch if properly secured.
- Trace the entire vent run from the dryer to the exterior wall, straightening any sections that show bends greater than 90 degrees.
- Check that vertical runs have support brackets every 8 feet, and that horizontal runs have support brackets every 12 feet.
- Push the dryer back toward the wall, stopping when there is 6 inches of clearance between the dryer’s rear panel and the wall surface.
- View the vent duct from both sides of the dryer to verify no compression or sharp bends have formed; the duct should maintain its full 4-inch diameter throughout.
- Confirm the duct path uses no more than two 90-degree elbows between the dryer and exterior termination point—each additional elbow reduces airflow by approximately 25%.
🔌
⚡ Step 9: Restore power and run a test cycle – Flow Sense error should clear
- Walk to your home’s electrical panel and flip the dedicated dryer circuit breaker from OFF to ON position (typically a double 30-amp breaker labeled “Dryer” or “Laundry”).
- Return to the dryer and press the power button located at the top center of the control panel; the display screen will illuminate showing “SENSOR DRY” as the default cycle.
- Open the dryer door by pulling the handle on the front left side.
- Place one dry bath towel (approximately 3 pounds) inside the drum to provide load for the test cycle.
- Close the door firmly until you hear a distinct click indicating the door latch has engaged.
- Press the “SENSOR Dry” button once on the control panel to select the default drying cycle.
- Press the “START/PAUSE” button (large circular button on the right side of the control panel) to begin the test cycle.
- Listen for the blower motor to start within 2-3 seconds; you’ll hear a humming sound increasing in pitch.
- Watch the control panel display for 30 seconds; the cycle time should appear (usually 35-45 minutes) without any error codes.
- Let the dryer run for 5 complete minutes while observing the control panel.
- Check that the Flow Sense indicator (4-bar icon at the top right of the display) shows 0, 1, or 2 bars illuminated, indicating normal airflow restriction.
- Press “START/PAUSE” to stop the test cycle after 5 minutes of normal operation.
- Open the dryer door and remove the test towel.
- Verify the exhaust duct behind the dryer is warm to touch, confirming proper airflow through the cleaned system.

🎯 Step 10: If error persists, check flow sensor on control board
- Unplug the dryer from the electrical outlet and wait 5 minutes for capacitors to discharge.
- Remove the dryer top panel by locating the two Phillips-head screws at the rear top edge, approximately 2 inches from each side corner, and remove them with a #2 Phillips screwdriver.
- Lift the top panel up and prop it against the wall behind the dryer.
- Locate the control board assembly mounted on the front right side of the dryer, inside a white plastic housing measuring approximately 8 inches wide by 6 inches tall.
- Identify the flow sensor pressure switch – a small circular component with a clear plastic tube attached, mounted on the left side of the control board housing.
- Disconnect the clear plastic tube from the flow sensor by pulling it straight off the nipple connector (requires approximately 5 pounds of force).
- Blow gently into the plastic tube while listening at the flow sensor – you should hear a distinct clicking sound indicating the switch is functioning mechanically.
- Using a multimeter set to continuity mode, disconnect the two-wire connector attached to the flow sensor (white connector with red and white wires).
- Touch multimeter probes to the two metal terminals on the flow sensor – the meter should show no continuity (open circuit).
- While probes are connected, blow into the sensor nipple with moderate pressure – the multimeter should immediately show continuity (closed circuit, typically less than 1 ohm resistance).
- Release air pressure – the meter should return to no continuity within 1 second.
- If the sensor fails either test (no click sound, doesn’t change continuity states, or stays closed after pressure release), replace the flow sensor assembly (part number 6501KW2001A).
- Reconnect the wire connector and plastic tube, pressing firmly until the tube seats completely onto the nipple (approximately 0.5 inches of insertion depth).

🔩 Step 4: Check exhaust vent connection at the back of the dryer
- Locate the exhaust vent outlet on the rear panel of the dryer, positioned center-left, approximately 8 inches from the left edge and 12 inches from the bottom.
- Identify the metal duct connector (typically 4 inches in diameter) attached to this exhaust outlet.
- Examine the connection type – you’ll see either a metal clamp with a screw head or a snap-on plastic fitting securing the vent hose to the dryer outlet.
- If a metal clamp is present, use a 5/16-inch nut driver or flathead screwdriver to loosen the clamp screw by turning counterclockwise 3-4 complete rotations until the clamp moves freely.
- Slide the metal clamp away from the connection point, moving it 2-3 inches down the flexible vent hose.
- Grip the flexible vent hose at the connection point and pull straight back with steady pressure to detach it from the dryer’s exhaust outlet.
- Look inside the dryer’s exhaust outlet opening – you should see a clear, unobstructed circular opening leading into the blower housing.
- Insert your fingers or a flashlight into the outlet opening and feel/look for lint buildup, which appears as gray, fibrous material coating the interior walls.
- Check the flexible vent hose end you just removed – the interior should be visible and relatively clean with minimal lint accumulation (less than 1/8-inch coating).
- Verify the exhaust outlet rim has no cracks, dents, or damage that would prevent an airtight seal.
- Reconnect the flexible vent hose by pushing it onto the exhaust outlet until it overlaps by at least 2 inches.
- Reposition the metal clamp over the overlapped section, centered 1 inch from the dryer outlet edge.
- Tighten the clamp screw clockwise until snug – the hose should not rotate or pull off when tugged with moderate force.
🔌
đź“‹ Step 5: Disconnect exhaust vent and inspect for lint accumulation
- Locate the exhaust vent connection at the rear of the dryer, approximately 4 inches from the bottom and centered horizontally on the back panel.
- Identify the metal clamp securing the vent hose to the dryer’s exhaust port—this is typically a 4-inch diameter screw-type clamp or spring clamp.
- If you have a screw-type clamp, use a 5/16-inch nut driver or flat-head screwdriver to turn the screw counterclockwise 3-4 full rotations until the clamp loosens enough to slide.
- If you have a spring clamp, squeeze the two tabs together using slip-joint pliers and slide the clamp 2-3 inches away from the connection point down the flexible vent hose.
- Grip the flexible vent hose with both hands and pull straight back away from the dryer exhaust port with steady pressure—it should slide off after moving 1-2 inches.
- Set the disconnected vent hose on the floor or drape it over the dryer top to keep it out of your work area.
- Look into the dryer’s exhaust port (the 4-inch circular opening on the back panel) and visually inspect for lint buildup along the interior walls.
- Insert a flashlight into the exhaust port opening to illuminate the transition duct that runs from the blower housing to this exit point.
- Use a dryer vent brush (18-24 inch flexible rod with bristles) and insert it fully into the exhaust port, rotating clockwise while pushing inward to dislodge accumulated lint.
- Pull the brush out while continuing to rotate, bringing lint debris with it—repeat this insertion and extraction 3-4 times until minimal lint appears on the brush.
- Inspect the flexible vent hose you removed by looking through one end toward a light source—you should see light passing through if the hose is clear.
- If the hose appears blocked, replace it with a new 4-inch diameter semi-rigid aluminum duct rather than attempting to clean heavily clogged flexible hose.
🧹
âś… Step 6: Use a vent cleaning brush to remove all lint from exhaust duct
- Insert a flexible dryer vent cleaning brush (minimum 10 feet long with 4-inch diameter bristles) into the exhaust duct opening at the back of the dryer where you disconnected the vent hose in the previous step.
- Push the brush forward into the duct using a clockwise rotation motion, turning the handle 2-3 full rotations for every 6 inches of forward progress.
- Continue pushing and rotating until you reach the exterior vent termination point (typically 5-25 feet depending on your installation) or until you feel firm resistance indicating you’ve reached the vent hood outside.
- Pull the brush back toward you while maintaining the clockwise rotation, using the same 2-3 rotations per 6 inches of movement.
- Remove the brush completely and clear the accumulated lint from the bristles by hand, collecting it in a trash bag.
- Repeat steps 1-5 a total of 3 times to ensure thorough cleaning, as the first pass loosens lint and subsequent passes remove it.
- Go outside to your exterior vent hood (typically mounted on an exterior wall or roof) and open the vent flap manually by lifting or pushing it upward.
- Insert the brush from the exterior opening and push inward 2-3 feet while rotating clockwise, then pull back out to capture any remaining lint near the exit point.
- Use a shop vacuum with a 2-inch diameter crevice tool attachment to vacuum out the exhaust duct opening at the back of the dryer, inserting it 12-18 inches into the duct.
- Verify successful cleaning by shining a flashlight into the duct opening—you should see smooth, silver metallic ductwork with no visible lint accumulation on the walls.
🧹
🔍 Step 7: Check exterior vent cap for blockages (birds’ nests, debris)
- Exit your home and walk around the exterior to locate the dryer vent exhaust. This will be a circular or rectangular opening in the wall, typically 4 inches in diameter, usually positioned 12-36 inches above ground level on the side or rear of your house.
- Stand directly in front of the vent cap and visually inspect the louvers or flaps. Look for visible debris such as lint accumulation, leaves, twigs, or nesting materials protruding from the opening.
- Grasp the outer edges of the vent cap hood with both hands. Most caps are friction-fit or held by 2-4 screws. If you see screws, use a Phillips-head screwdriver #2 to remove them by turning counterclockwise.
- Pull the vent cap straight away from the wall once fasteners are removed. Set the cap on the ground with the opening facing up.
- Look inside the vent pipe opening in your wall. Insert your flashlight into the opening and shine it 6-12 inches deep, checking for bird nests (look for circular formations of twigs and grass), lint buildup (appears as gray-white fuzzy material), or other obstructions.
- If you find a bird nest or debris, reach in with your gloved hand and pull the material straight out. For compacted lint, use a dryer vent brush (24-36 inch flexible rod with bristles) and insert it fully into the duct, rotating clockwise while pushing inward, then pull back while continuing rotation.
- Examine the vent cap louvers or flapper door. Pivot the flapper back and forth 5-10 times to verify it moves freely without sticking. Remove any lint stuck to the louvers by wiping with a dry cloth.
- Reattach the vent cap by aligning it with the wall opening and either pressing firmly until secure or reinstalling the 2-4 screws, tightening clockwise until snug.
- The flapper should rest in the closed position but open easily when you blow air toward it from 6 inches away.
✔️
đź’ˇ Step 8: Reconnect vent securely and ensure no kinks or restrictions
- Locate the 4-inch diameter vent outlet port on the rear panel of the dryer, positioned 8 inches from the bottom and centered horizontally.
- Inspect the rigid or semi-rigid metal vent duct (minimum 4-inch diameter) that should still be connected to your wall exhaust port from earlier in the repair.
- Slide the dryer vent clamp (4-inch hose clamp) over the end of the vent duct that will connect to the dryer, positioning it approximately 1 inch from the duct’s end.
- Push the vent duct straight onto the dryer’s exhaust outlet port until the duct covers at least 2 inches of the port’s ribbed surface.
- Position the hose clamp directly over where the duct and port overlap, approximately ½ inch from the outer edge of the port.
- Tighten the clamp using a 5/16-inch nut driver or flat-head screwdriver, turning the screw clockwise until the clamp is snug against the duct—approximately 3-4 full rotations after initial contact.
- Attempt to pull the duct off the port by hand; it should not move more than 1/8 inch if properly secured.
- Trace the entire vent run from the dryer to the exterior wall, straightening any sections that show bends greater than 90 degrees.
- Check that vertical runs have support brackets every 8 feet, and that horizontal runs have support brackets every 12 feet.
- Push the dryer back toward the wall, stopping when there is 6 inches of clearance between the dryer’s rear panel and the wall surface.
- View the vent duct from both sides of the dryer to verify no compression or sharp bends have formed; the duct should maintain its full 4-inch diameter throughout.
- Confirm the duct path uses no more than two 90-degree elbows between the dryer and exterior termination point—each additional elbow reduces airflow by approximately 25%.
🔌
⚡ Step 9: Restore power and run a test cycle – Flow Sense error should clear
- Walk to your home’s electrical panel and flip the dedicated dryer circuit breaker from OFF to ON position (typically a double 30-amp breaker labeled “Dryer” or “Laundry”).
- Return to the dryer and press the power button located at the top center of the control panel; the display screen will illuminate showing “SENSOR DRY” as the default cycle.
- Open the dryer door by pulling the handle on the front left side.
- Place one dry bath towel (approximately 3 pounds) inside the drum to provide load for the test cycle.
- Close the door firmly until you hear a distinct click indicating the door latch has engaged.
- Press the “SENSOR Dry” button once on the control panel to select the default drying cycle.
- Press the “START/PAUSE” button (large circular button on the right side of the control panel) to begin the test cycle.
- Listen for the blower motor to start within 2-3 seconds; you’ll hear a humming sound increasing in pitch.
- Watch the control panel display for 30 seconds; the cycle time should appear (usually 35-45 minutes) without any error codes.
- Let the dryer run for 5 complete minutes while observing the control panel.
- Check that the Flow Sense indicator (4-bar icon at the top right of the display) shows 0, 1, or 2 bars illuminated, indicating normal airflow restriction.
- Press “START/PAUSE” to stop the test cycle after 5 minutes of normal operation.
- Open the dryer door and remove the test towel.
- Verify the exhaust duct behind the dryer is warm to touch, confirming proper airflow through the cleaned system.
🔍
🎯 Step 10: If error persists, check flow sensor on control board
- Unplug the dryer from the electrical outlet and wait 5 minutes for capacitors to discharge.
- Remove the dryer top panel by locating the two Phillips-head screws at the rear top edge, approximately 2 inches from each side corner, and remove them with a #2 Phillips screwdriver.
- Lift the top panel up and prop it against the wall behind the dryer.
- Locate the control board assembly mounted on the front right side of the dryer, inside a white plastic housing measuring approximately 8 inches wide by 6 inches tall.
- Identify the flow sensor pressure switch – a small circular component with a clear plastic tube attached, mounted on the left side of the control board housing.
- Disconnect the clear plastic tube from the flow sensor by pulling it straight off the nipple connector (requires approximately 5 pounds of force).
- Blow gently into the plastic tube while listening at the flow sensor – you should hear a distinct clicking sound indicating the switch is functioning mechanically.
- Using a multimeter set to continuity mode, disconnect the two-wire connector attached to the flow sensor (white connector with red and white wires).
- Touch multimeter probes to the two metal terminals on the flow sensor – the meter should show no continuity (open circuit).
- While probes are connected, blow into the sensor nipple with moderate pressure – the multimeter should immediately show continuity (closed circuit, typically less than 1 ohm resistance).
- Release air pressure – the meter should return to no continuity within 1 second.
- If the sensor fails either test (no click sound, doesn’t change continuity states, or stays closed after pressure release), replace the flow sensor assembly (part number 6501KW2001A).
