✔️ Step-by-Step Repair Instructions
🔌
🔧 Step 1: Disconnect power to the dryer
- Locate your home’s electrical panel (breaker box), typically found in the basement, garage, utility room, or exterior wall of your home.
- Open the breaker panel door by pulling the handle or lifting the cover.
- Identify the dryer circuit breaker, which will be a double-pole breaker (two switches connected together) labeled “Dryer” or “Electric Dryer,” typically rated at 30 amps.
- Flip both switches of the double-pole breaker to the OFF position by pushing them firmly to the right or down (opposite direction from ON).
- Use a non-contact voltage tester or circuit tester to verify power is off—place tape over the breaker switches and write “DO NOT TURN ON – DRYER REPAIR IN PROGRESS” on the tape.
- Walk back to the dryer location and pull the dryer away from the wall approximately 3-4 feet to access the rear panel.
- Locate the power cord connection point at the lower rear of the dryer, positioned approximately 8 inches from the bottom and centered horizontally.
- Identify the power cord type: either a 3-prong (older installations with red, black, and green wires) or 4-prong (newer installations with red, black, white, and green wires) connected to a terminal block.
- Use a non-contact voltage tester against the power cord terminals and the dryer’s metal housing to confirm zero voltage—the tester should not light up or beep.
- Unplug the power cord from the wall outlet by gripping the plug body (not the cord) and pulling straight out with firm pressure.
- Verify the outlet is empty and the power cord is completely disconnected.

🛠️ Step 2: Locate door switch assembly (usually near the door latch)
- Open the dryer door fully and face the door opening where the door normally closes.
- Look at the door strike area on the front panel – this is the recessed cavity where the door latch engages when closed, located on the right side of the door opening approximately 14 inches from the top edge.
- Direct your flashlight into this strike cavity to illuminate the interior components.
- Identify the door switch assembly – it appears as a white or cream-colored plastic rectangular housing measuring approximately 1.5 inches long by 0.75 inches wide, mounted vertically inside the strike cavity.
- Observe the small white plastic actuator button protruding from the switch housing – this is what the door latch pushes when the door closes, measuring approximately 0.25 inches in diameter.
- Trace the wire harness connected to the back of the door switch – you’ll see a 2-wire connector with white and black wires running from the switch assembly into the cabinet interior.
- Note the single mounting screw securing the switch assembly, located at the top of the switch housing – this requires a Phillips #2 screwdriver for removal.
- Verify you’ve located the correct component by pressing the white actuator button with your finger – you should feel a distinct click and approximately 0.125 inches of travel when pressed.
- Check the switch assembly part number stamped on the white plastic housing, reading 6601ER1004C (older models may show 6601ER1004A or 6601ER1004B).
- Examine the mounting area around the switch for any visible damage, cracks in the plastic housing, or signs of overheating such as brown discoloration.
🔧
⚙️ Step 3: Remove door switch mounting screws
- Locate the door switch assembly on the right-hand side of the dryer door opening, positioned approximately 2 inches down from the top edge of the cabinet frame.
- Identify the white plastic door switch housing – it measures roughly 2 inches long by 1 inch wide and has a small black plastic actuator button protruding from its face.
- Find the two Phillips-head mounting screws securing the door switch to the metal cabinet frame – one screw is located at the top of the switch housing, the other at the bottom, spaced approximately 1.5 inches apart.
- Insert a Phillips-head #2 screwdriver into the top screw and rotate counterclockwise 8-10 full turns until the screw releases completely from the cabinet frame.
- Place this screw in your parts container – these screws are chrome-colored, approximately 0.5 inches long with coarse threads.
- Insert the Phillips-head #2 screwdriver into the bottom screw and rotate counterclockwise 8-10 full turns until this screw also releases completely.
- Place the second screw with the first screw in your parts container.
- Grasp the door switch housing and pull it straight out from the cabinet opening approximately 2 inches – the switch will remain connected by its wire harness at this point.
- Allow the switch to hang freely by its wiring while keeping the wires from touching any metal surfaces.
🧪
🔩 Step 4: Test switch continuity with multimeter – should show continuity when door is closed
- Set your digital multimeter to the continuity setting, indicated by a diode symbol or sound wave icon on the dial.
- Locate the two wire terminals on the door switch—you’ll see two metal tabs protruding from the back of the switch body, spaced approximately 0.5 inches apart.
- Touch one multimeter probe to each of the two metal terminals on the door switch. The probe order doesn’t matter for continuity testing.
- With the probes still connected to the terminals, press the door switch plunger fully inward using your finger—push it approximately 0.25 inches until it stops.
- Watch the multimeter display while holding the plunger pressed in. A functioning switch will show “0.0” or near-zero ohms, and the multimeter will emit a continuous beep tone.
- Release the plunger and let it spring back to its extended position. The multimeter reading should immediately change to “OL” (over limit) or “1”, and the beep should stop.
- Repeat this press-and-release test 5 times in succession. The switch should consistently show continuity (beep and low resistance) when pressed and no continuity (no beep and “OL” reading) when released.
- If the switch fails to show continuity when pressed, shows intermittent readings during the 5 test cycles, or shows continuous continuity even when released, the door switch (part number 6601ER1004C) has failed and requires replacement.
- If the switch passes all tests, remove the multimeter probes and proceed to reconnecting the wiring. The door interlock system is functioning correctly, and your dryer issue lies elsewhere in the circuit.
🧪
📋 Step 5: If switch shows no continuity when closed, it’s faulty
- Set your multimeter to the continuity setting (typically marked with a diode symbol or speaker icon that produces a beep).
- Touch the two multimeter probes together to verify the meter is working – you should hear a beep and see a reading near 0 ohms.
- Locate the two metal terminals on the door switch body – they are spaced approximately 0.5 inches apart on the bottom or side of the switch housing.
- Place one multimeter probe on each terminal while the switch actuator button is in the pressed (closed) position.
- Press the switch button firmly with your thumb if it isn’t already depressed – you need at least 0.25 inches of travel until you feel it bottom out.
- Watch the multimeter display while holding the button pressed:
- Release the switch button and verify the reading changes to “OL” with no beep – this confirms the switch opens properly when released.
- Repeat the test 5 times, pressing and releasing the button, to check for intermittent failures – the readings should be consistent each time.
- If the switch fails to show continuity (beep and low resistance) when pressed closed, write down the part number stamped on the switch body for ordering a replacement – LG part number 6601ER1004C for this model.
- If the switch shows proper continuity in both positions consistently, the door switch is functioning correctly and is not the source of your dryer problem – proceed to check other components in the heating circuit.

✅ Step 6: Check door latch alignment – misalignment can prevent proper switch activation
- Open the dryer door fully and locate the door strike assembly – the plastic protrusion mounted on the door’s right edge, approximately 3 inches down from the top corner.
- Examine the door catch mechanism inside the dryer cabinet opening on the right side, positioned to receive the door strike when closed.
- Close the door slowly while watching where the strike enters the catch opening – the strike should slide directly into the center of the rectangular catch opening without scraping the sides.
- If misaligned, open the door and locate the two Phillips-head screws securing the door catch assembly to the dryer frame (one screw at top, one at bottom of the catch bracket).
- Loosen both screws using a Phillips #2 screwdriver – turn 3-4 complete rotations counterclockwise until the catch assembly can slide within its mounting slots.
- Partially close the door and observe the strike’s natural alignment path into the catch opening.
- Adjust the catch assembly up, down, forward, or backward within its slotted mounting holes until the strike enters the center of the opening smoothly – typically requires moving the assembly 1/8 to 1/4 inch.
- Hold the catch assembly in the corrected position and tighten the top screw first, then the bottom screw – turn each clockwise until snug but not overtightened (approximately 10-12 inch-pounds).
- Close the door completely and listen for a solid click sound, indicating the door switch inside the catch assembly is being activated.
- Verify proper engagement by gently pulling the closed door outward – it should resist opening with approximately 5-10 pounds of force.
- If the door still doesn’t click or activate properly, loosen the screws again and shift the catch assembly an additional 1/16 inch toward the door until proper engagement occurs.

- Press the switch plunger – the meter should read 0 ohms (continuity) when pressed and infinite ohms (no continuity) when released.
- If the switch failed testing, install the new door switch (part number 6601ER1004C) by connecting the 2-wire white connector to the terminals – it only fits one direction.
- Position the switch into the mounting bracket with the plunger facing toward the door opening.
- Install the 2 Phillips-head screws and tighten until the switch housing is flush against the cabinet frame – approximately 8-10 inch-pounds of torque.
- Close the door and observe the door strike (metal hook on the door) as it enters the switch cavity – it should depress the switch plunger by at least 1/8 inch.
- If the strike misses the plunger or barely touches it, loosen the 4 Torx T20 screws on the door hinge (2 screws per hinge, top and bottom door hinges).
- Shift the door right or left by 1/16 inch increments until the strike fully engages the switch plunger.
- Retighten all 4 hinge screws to 18-20 inch-pounds.

đź’ˇ Step 8: Install new door switch and verify proper door closure activates switch
- Hold the new door switch (LG part number 6601ER1004C) with the wire terminals facing toward the dryer interior and the actuator button protruding outward.
- Align the two plastic mounting tabs on the back of the switch body with the rectangular slots in the door frame opening, located on the right side of the door opening, 3 inches down from the top edge.
- Push the switch straight into the mounting slots until you hear a distinct click—the switch should sit flush with the door frame surface with no gaps visible around the edges.
- Connect the 2-wire white connector to the terminals on the back of the switch by pushing it straight on until it seats completely—you’ll feel resistance stop and the connector cannot be pulled off by hand without depressing the locking tab.
- Route the wire harness along the existing channel in the door frame, securing it with the plastic wire clip located 2 inches below the switch position.
- Close the dryer door slowly while watching the door strike plate (the metal piece protruding from the door itself at the same height as the switch).
- Observe the white plastic actuator button on the switch depress inward approximately 1/4 inch as the door strike plate makes contact—you should hear a single audible click when the button fully depresses.
- Open the door and verify the actuator button springs back out to its extended position within 1 second.
- Connect power to the dryer and set the control dial to any drying cycle without starting it.
- Close the door completely—the control panel should illuminate and become fully responsive.
- Open the door while observing the control panel—the display should go dark immediately when the door opens more than 1/2 inch, confirming the switch is cutting power correctly.

⚡ Step 9: Reassemble and test dryer operation
- Position the dryer drum back into the cabinet by tilting the front edge down at a 30-degree angle and sliding it onto the rear support rollers until you feel it seat completely.
- Rotate the drum clockwise by hand one full revolution to verify the belt is properly seated on the drum, motor pulley, and idler pulley without rubbing against any cabinet edges.
- Lift the front of the drum approximately 2 inches while aligning the two front support rollers (one on each side) onto their metal mounting brackets inside the front cabinet corners.
- Reconnect the door switch wire harness by pushing the white plastic connector onto the metal terminals on the door switch until it clicks—you’ll hear an audible snap.
- Reconnect the moisture sensor wire connector (white 2-wire plug) located at the front right side of the drum opening by pushing it straight on until seated flush.
- Position the front top panel back onto the cabinet, aligning the two metal tabs at the bottom edge into their slots, then pushing the top edge back until it’s flush with the cabinet sides.
- Reinstall the two Phillips-head screws at the top front edge, 3 inches from each side, tightening with a #2 Phillips screwdriver until snug (approximately 1/4 turn past finger-tight).
- Replace the lint filter into its housing at the top front.
- Plug the dryer power cord into the 240V outlet.
- Turn the gas supply valve counterclockwise to the ON position (handle parallel with the gas line).
- Select the NORMAL DRY cycle, press START, and verify the drum rotates smoothly without squealing or grinding sounds.
- Open the dryer door within 10 seconds—the drum should stop immediately, confirming the door switch operates correctly.
- Close the door, press START again, and run the dryer for 3 complete minutes while monitoring for proper heating and normal operation sounds.

✅ Step 6: Check door latch alignment – misalignment can prevent proper switch activation
- Open the dryer door fully and locate the door strike assembly – the plastic protrusion mounted on the door’s right edge, approximately 3 inches down from the top corner.
- Examine the door catch mechanism inside the dryer cabinet opening on the right side, positioned to receive the door strike when closed.
- Close the door slowly while watching where the strike enters the catch opening – the strike should slide directly into the center of the rectangular catch opening without scraping the sides.
- If misaligned, open the door and locate the two Phillips-head screws securing the door catch assembly to the dryer frame (one screw at top, one at bottom of the catch bracket).
- Loosen both screws using a Phillips #2 screwdriver – turn 3-4 complete rotations counterclockwise until the catch assembly can slide within its mounting slots.
- Partially close the door and observe the strike’s natural alignment path into the catch opening.
- Adjust the catch assembly up, down, forward, or backward within its slotted mounting holes until the strike enters the center of the opening smoothly – typically requires moving the assembly 1/8 to 1/4 inch.
- Hold the catch assembly in the corrected position and tighten the top screw first, then the bottom screw – turn each clockwise until snug but not overtightened (approximately 10-12 inch-pounds).
- Close the door completely and listen for a solid click sound, indicating the door switch inside the catch assembly is being activated.
- Verify proper engagement by gently pulling the closed door outward – it should resist opening with approximately 5-10 pounds of force.
- If the door still doesn’t click or activate properly, loosen the screws again and shift the catch assembly an additional 1/16 inch toward the door until proper engagement occurs.
