ШагиSteps

Gather tools and personal protection

Gather a Phillips screwdriver for the cabinet screws.
A drill driver can speed up removal of the many screws.
Keep a digital multimeter ready for voltage and resistance checks.
Have a vacuum with a flexible hose ready to clear lint from the vent path.
Wear cut-resistant gloves and long sleeves to protect against sharp sheet-metal edges.

Confirm correct power at the terminal block

Remove the single rear screw and lift off the small metal cover over the terminal block.
Inspect cord lugs and the block for burnt or blackened spots.
Set the meter to AC volts and read between center neutral and left hot; expect about 120 V.
Move the probe to the right hot and confirm another 120 V.
Measure across the two outer hots and verify 208–240 V AC.
Correct house wiring or breaker issues before opening the dryer if any reading is low.

Isolate electrical power

Unplug the dryer from the wall outlet before any internal work.

Remove the top panel

Back out the two Phillips screws at the rear corners of the top panel.
Slide the panel rearward and lift it off the cabinet.
Retrieve the folded tech sheet inside the cabinet for later reference.

Detach the control interface

Remove the two screws securing the user interface to the front bulkhead.
Disconnect the multipin harness and photograph its position for reassembly.
If you need more slack, remove the two bracket screws from the wire trunk.
Set the interface aside where it cannot fall or snag any wires.

Remove the front panel and door

Open the door and remove the two screws recessed in the lint filter housing.
Close the door and remove the two bottom screws near each lower corner.
Take out the two top screws securing the panel to the chassis while supporting the door.
Tilt the panel forward, unplug the door-switch harness, and lift the panel up off its locating tabs.
Place the panel face-down on a soft surface to prevent scratches.

Remove the front bulkhead

Remove the two lower screws that fasten the bulkhead to the side panels.
Squeeze the cable-tie clip and release the door-switch harness from the bulkhead.
Lift the bulkhead up off its side tabs and pull it clear of the cabinet.

Release the belt and pull the drum

Reach inside on the right and pull the idler pulley to the left to slacken the belt.
Slip the belt off the motor pulley.
Use the belt as a sling to lift and slide the drum straight out of the front opening.
Use gloves to avoid cuts from sharp cabinet edges or stray metal pieces.

Clear the lint duct

Vacuum the lint filter housing and vent duct until airflow is unobstructed.
If the duct is badly packed, reach in and pull out the lint wad by hand.

Check blower thermistor resistance

Pull the two wires off the black thermistor on the blower housing.
Set the meter to the 20 to 200 kΩ range and probe the terminals.
A room-temperature reading of 50 to 55 kΩ usually indicates a good sensor.
Any value far outside that range or OL usually means the thermistor is defective.
The replacement thermistor used in the video is part 134587700.

Test the blower outlet fuse

Disconnect the fuse leads on the exhaust duct.
Measure resistance; a good fuse reads roughly 0 Ω.
OL or infinite resistance indicates an open fuse that needs replacement.

Verify thermostat continuity

Unplug the two wires from the rear thermostat on the heating canister.
Check continuity; near-zero ohms confirms the thermostat is functional.
Replacement thermostat part 3204267
Replace the thermostat if the meter shows OL or very high resistance.

Verify thermal fuse continuity

Remove the wires from the middle-mounted thermal fuse.
A good fuse reads close to 0 Ω; OL means it is blown and must be replaced.
Replacement fuse part 137032600
Whenever this fuse fails, clean the vent system and replace the thermostat as a precaution.

Measure heating element resistance and ground fault

Disconnect all heating-element wires and note their positions on either 3-plus-1 or 2-wire models.
Measure between the right terminal and each left terminal; 25 to 30 Ω is normal for 3-plus-1 elements.
Measure between the two left terminals; about 50 Ω is expected.
On 2-wire elements, expect roughly 10 Ω across the pair.
Probe each terminal to the metal shell. Any reading other than OL indicates a grounded coil that must be replaced.
The replacement heater canister shown in the video is part 137114000.

Remove the heating canister

Label and disconnect all wires from the canister and its sensors.
Remove the two front screws securing the canister feet to the base.
Use a stubby driver to remove the hidden screw at the back-right bulkhead tab.
Lift the canister forward and out of the dryer cabinet.

Transfer sensors and assemble the new canister

Unscrew the thermal fuse and thermostat from the old shell and install new or reused parts on the replacement.
Remove the two inner faceplate screws and separate the cover to access the element.
Seat the replacement element so its legs fit the recesses, then reinstall the foot screws.
Straighten any bent cover lip so it sits flush with the shell.

Install the replacement canister

Slide the canister rear flange into the bulkhead opening and lower the feet into their base slots.
Secure the feet and reinstall the rear retaining screw if accessible.
Reconnect each wire to its original terminal, matching your photos.
If slack is short, reroute the right-side wire and secure it with a high-temperature zip tie rather than bending the spade.

Re-install the drum and belt

Rest the rear rim of the drum on the two rear support rollers.
Loop the belt around the drum groove with the ribbed side inward.
Pull the idler to the left and guide the belt around the motor pulley and idler groove.
Rotate the drum by hand; smooth turning confirms proper belt routing and blower engagement.

Reassemble bulkhead and front panel

Hang the bulkhead on its top tabs, seat it, and install the two bottom screws.
Clip the door-switch harness back into the bulkhead and plug it into the control board.
Reconnect the door-switch plug to the front panel, lower the panel onto its locating tabs, and install the two top screws.
Drive the two bottom panel screws and the two large filter-housing screws accessed through the open door.

Refit the control interface and top cover

Plug the interface harness into its original socket on the board.
Engage the interface tabs and fasten its two mounting screws.
Slide the top panel forward and secure it with the two rear screws.

Inspect the control board for visible damage

Unplug the dryer, remove the crossbar screws, and lift the board out of its cradle.
Unlatch the plastic tabs and separate the PCB from the housing.
Examine both sides for burnt relays, dark traces, or cracked solder joints.

Perform live voltage checks on the board outputs

Reconnect all harnesses to the loose board, but leave the board unsecured so you can access the test points.
Use the tech sheet to locate pins J52, J71, and J73 on the board.
With the dryer running, measure between the black L1 wire at the terminal block and each pin. A reading of 208 to 240 V indicates a good relay.
A reading below about 200 V usually indicates a failed relay and the board should be replaced.
Use extreme caution while probing live circuits.

Final assembly and functional test

Unplug the dryer, mount the control board, and reinstall its crossbar screws.
Verify every harness and screw is secure, restore power, and run a timed-dry cycle.
Confirm the drum tumbles, heat is present, and airflow is strong through the exhaust.

After reassembly, run a timed-dry cycle and confirm that the drum tumbles and the exhaust reaches normal drying temperature. Repair didn't go as planned? Ask our Answers community for help.
