ШагиSteps

Inspect the timer knob and shaft

Turn the timer clockwise and listen for a strong clicking sound from the mechanism.
Pull the knob straight off and examine the plastic insert for cracks or stripping.
Check the exposed metal shaft for rounding or breakage that prevents rotation.
Replace the knob if the insert is damaged or replace the timer if the shaft is broken.

Examine the push to start button

Use a flat-blade screwdriver to pry the plastic button from the console without twisting the clips.
Look for cracks, deformation, or missing plastic that could keep the plunger from reaching the switch.
Press directly on the exposed switch body to see whether the dryer starts with the button removed.

Check motor start windings by hand-spin

Open the door and tape the door switch closed so the machine thinks the door is shut.
Rotate the drum counter-clockwise while pressing the start button.
If the drum begins to run only after the manual spin, the motor start winding is failing.
A drum that will not turn by hand indicates an obstruction, while a drum that turns too freely may mean a broken belt.

Determine if the dryer only runs when held

Hold the start button and see whether the motor stops as soon as the button is released.
Constant button pressure points to a failed centrifugal switch on the motor or a bad belt switch that will be tested later.

Inspect the incoming power connections

Slide the dryer forward, remove the single quarter-inch screw and drop the rear lower cover that guards the cord block.
Look for burnt, loose or broken wires on the terminal block and power cord ends.
Repair or replace the terminal block or cord if any damage is found.

Verify supply voltage at the cord block

Set the multimeter to AC volts, keep the dryer plugged in and measure center to left then center to right posts; both should read about 120 V.
Measure across the two outer posts and confirm 208-240 V.
If voltage is low or excessive, reset the breaker or call an electrician to correct the supply.

Test the main thermal fuse

Unplug the dryer, set the meter to continuity and touch a lead to each terminal of the small fuse on the blower housing base.
A good fuse reads 0 Ω or beeps; an open fuse shows OL and must be replaced.

Remove the console back panel

Take out two quarter-inch screws on the plastic end caps and four more securing the steel rear console cover.
Lift the panel up then out and note the wiring schematic glued to its inside surface.

Check the push to start switch electrically

Remove the green ground screw so the console can pivot upward and clear the top.
Put the meter on continuity, back-probe the top red and bottom brown wires and press the start button.
A good switch shows 0 Ω when pressed; an OL reading means the switch is faulty.

Optional tests on timer contacts and resistor

With the schematic as reference, rotate the timer to a heat cycle and check continuity through the motor circuit terminals.
Measure the brown wire resistor and confirm roughly 4.5 kΩ; OL indicates failure.

Pop the top and confirm belt condition

Remove two Phillips screws from the rear corners of the top panel and two more inside the door opening.
Slide a flat blade under the front seam to release the spring clips and raise the lid slightly.
Peek inside to verify the drum belt is intact and not shredded before moving on.

Disconnect the top light harness if fitted

Support the raised lid and unplug the small lamp harness at the left hinge area, pressing the locking tab while separating.

Remove the front panel and door assembly

Extract one quarter-inch screw from each front side flange and prepare to lift the entire door panel.
Pull the panel forward and upward to clear the three bottom fingers that support it.
Wear work gloves here. The front panel edges are sharp, and the short door-switch harness does not leave much room to set the panel down safely.
Slide the plastic guard aside, squeeze the latch, unplug the switch harness, and set the door panel aside.

Release belt tension at the idler pulley

Reach your right hand behind the blower housing, pull the idler arm to the right and hook its metal hub on the motor bracket tab.
Slip the drum belt off the motor pulley and idler wheel completely.

Lift out the drum

Grab the loose belt, raise the drum slightly and pull it straight forward, keeping it inside the stamped side channels.
Guide the rear bearing out of its socket while avoiding snags on the belt or cabinet edges.

Clean lint and inspect interior components

Vacuum loose lint from the motor, blower housing and cabinet floor to restore airflow and prevent future fuse trips.
Use a flexible dryer cleaning kit to reach tight pockets around the motor windings if heavy buildup is present.

Test the drum outlet thermostat

Pull one blue wire from the two-terminal thermostat on the blower outlet and read resistance across the exposed spades.
A good thermostat shows near 0 Ω; OL means it must be replaced.
Measure the small orange terminals and expect roughly 9 kΩ at room temperature.

Check safety and high-limit fuses on the heater

Remove one lead from the small fuse on the heater housing and verify continuity at 0 Ω.
Repeat the test on the adjacent high-limit thermostat; OL indicates the part is blown.

Evaluate the belt switch operation

Keep the meter on continuity, pull the idler arm until you hear a click and watch for 0 Ω on the meter.
No reading under full tension means the belt switch is defective.

Remove and test the door switch

Press the hidden clip on the switch body, slide it toward the drum and withdraw the switch from the panel.
Using the schematic, verify continuity between the white and brown wires with the switch released for the light circuit.
Close the switch plunger and verify continuity now shifts to the brown and yellow wires that feed the motor circuit.
Any failure to transfer continuity confirms the switch is bad.

Install the new door switch

Slide the replacement switch into the front panel until the side clip locks behind the metal skin.
Reconnect the three-wire harness firmly, ensuring the plastic guard snaps back over the connector.

Reinstall the drum and belt

Pull the idler arm onto its motor mount tab to hold tension back while you work.
Seat the belt in the rear drum groove, lift the drum and slide the rear bearing into its socket at the back panel.
Loop the belt around the motor pulley, release the idler arm and verify the belt tracks in the center of both pulleys.

Verify smooth drum rotation

Rotate the drum by hand several turns and confirm the belt rides smoothly and no scraping sounds are present.

Reattach the front panel and door

Hang the panel on the three lower chassis fingers and pivot it toward the cabinet until flush.
Reconnect the door switch harness if you left it detached and tuck the plastic guard back in place.
Install the two quarter-inch screws through the side flanges to secure the panel.

Close the top and test operation

Swing the lid down, press along the front edge until both spring clips snap into the chassis.
Plug the dryer in and press start to confirm that it starts and runs normally.

Secure remaining screws and console

Drive the two long Phillips screws into the door opening to lock the top to the front bulkhead.
Insert the two matching screws at the rear corners of the lid.
Pivot the console down, align the six plastic fingers with their slots and tap forward to lock.
Reinstall the green ground screw and the four quarter-inch screws that hold the metal console cover.
Finish by replacing the two top console mounting screws.

Final confirmation

Run the dryer through a full heat cycle and monitor for normal sound, drum rotation and temperature rise.

Once the failed switch, belt path, or control issue is corrected, reassemble the dryer fully and confirm it starts without hesitation. Repair didn't go as planned? Ask our Answers community for help.
