If a Whirlpool stackable or front-load dryer (including many Whirlpool Duet-style models) squeals, grinds, or makes other unusual noises, the cause is usually a physical obstruction or wear in the belt-and-roller system. This guide shows how to safely open the dryer, check the blower wheel, belt, drum rollers, and idler pulley, clean out debris, and replace common wear parts using a basic dryer maintenance kit (typically a belt, rollers, an idler pulley, and new retainers). Model details can vary, so expect small differences in screw locations and braces.

ШагиSteps

Remove the rear access cover and check the belt

Unplug the dryer before starting the repair.
Use a nut driver to remove the two hex screws securing the rear access cover.
Pull the top of the cover rearward, then lift it up and out.
Inspect the drum belt for fraying or damage, because a damaged belt can cause noise.
Some models use 5/16 inch hex screws here, but others may use 1/4 inch.

Remove the control interface from the top front

Confirm the dryer is unplugged before disconnecting any wiring.
Remove any cross brace that blocks access to the front area if the model has one.
Use a screwdriver to remove the two screws securing the control interface.
Remove the press-mount cable tie from the front bracing.
Disconnect the harness from the control board to the interface.
Rock the interface toward the front and up, feed the harness through the metal bulkhead, and remove the interface.

Remove the front panel

Use a 1/4" nut driver to remove the four screws securing the bottom of the front panel from underneath the dryer.
Tilting the dryer back can make the bottom screws easier to reach, but it is optional.
Open the door, then use a Phillips screwdriver to remove the two large screws at the bottom of the lint filter housing.
Unclip the door switch wire harness.
Remove the three screws across the top of the front panel, and remove the middle screw last so the panel doesn’t lurch forward.
Route the door switch harness through the bulkhead, lift the front panel up, and pull it away to remove it.

Disconnect the moisture sensor and remove the top bracing

Disconnect the moisture sensor connector from the lower right of the bulkhead.
Use a 1/4" nut driver to remove the four screws securing the top front bracing.
Lift the bracing up and out, and work it free from the small locking tabs on each side.
Some models may not require removing this bracing, and some may have additional braces to remove.

Remove the blower housing screws and the bulkhead

Remove the screws from the blower housing, including the bottom screw and any additional blower housing screws your model uses.
Some models also have a center blower housing screw.
Remove the four bulkhead screws around the edges of the bulkhead using a 1/4" nut driver.
Lift the bulkhead up to clear the two support arms, then pull it forward and out to remove it.
If the bulkhead hangs up on the drum’s front rollers, rotate the drum slightly to help dislodge it.

Check the blower wheel area for obstructions

Inspect the blower fan and blower housing on the left side for debris or anything rubbing.
Check both the fan side and the bulkhead side you just removed for anything lodged in the housing.
Rotate the drum by hand with the belt still installed to see if the noise is gone after clearing the blower area.
If the noise stops here, the issue may have been an obstruction rather than a worn part.

Remove the belt from the idler and pull out the drum

Wear gloves and long sleeves if possible, because the dryer chassis has sharp metal edges.
Pull the idler pulley to the left to relieve belt tension.
Pull the belt rearward to free it from the idler pulley, then move the belt up and away from the motor pulley.
Pull up on the belt and pull the drum toward the front of the dryer to remove it.
Watch for the belt snagging on chassis cutouts, because some models have tight clearances.

Inspect for common noise causes

Inspect the inside of the dryer for items obstructing the drum or rubbing on rotating parts.
Check the rollers for flat spots, seized rollers that don’t move, and damage to roller shafts.
Inspect the idler pulley for damage or rough movement.
Inspect the top of the rear bulkhead area and the rear drum felt for wear that could cause metal-on-metal contact.
If the rear felt is badly damaged, the repair may require replacing the rear bulkhead, the drum, or the drum felt.

Replace the idler pulley if it is worn

Spin the idler pulley by hand and look for flat spots, wobble, or roughness.
Use a small flathead screwdriver to pry off the plastic triangle retainer from the idler pulley shaft.
Slide the idler pulley off the shaft, then install the replacement pulley.
Reinstall the triangle retainer to lock the idler pulley in place.

Clean the dryer and service the rollers

Vacuum the inside of the dryer, focusing on the roller areas and the blower area.
Inspect each drum roller for debris wrapped around the shaft, because buildup can stop the roller from turning and create noise.
Use a small flathead screwdriver to remove the plastic triangle retainer, then pull the roller off the shaft.
Clean the shaft and install a cleaned roller or a replacement roller, then install a clean triangle retainer.
Install the small metal retainer from the kit on the end of the shaft, and press it into place using a 7/16 inch driver or a deep socket.
Repeat the same roller service on the rollers mounted to the bulkhead, because many models have two rollers there.
If roller shafts have rust or grime, clean them with sandpaper, and only replace shafts if they are bent or badly damaged.
Don’t forget the metal retainers after the plastic clips, because they help keep the rollers secured.

Check the belt, blower cover, and motor pulley

Compare the replacement belt to the original belt and confirm it fits the drum and routing correctly before reassembly.
Inspect the blower housing cover that attaches to the bulkhead, and confirm it is in good shape and free of hidden debris.
Inspect the motor pulley and the motor, because either can cause noise.
Turn the motor pulley by hand, and if it makes noise, check for an obstruction in the blower wheel or motor bearing issues.
A bad motor usually requires motor replacement, but it is rare on these dryers.

Reinstall the drum and route the belt

Set the drum into the chassis and use the belt to maneuver the drum into place between the bulkhead area and the two rear rollers.
Thread the belt onto the motor pulley, then press the idler pulley to the right to tension the belt.
Rotate the drum by hand to confirm it turns smoothly with no noises or obstructions.
Watch the blower wheel area while rotating the drum, because it should move without rubbing.
Note: The belt routing should form a Z-shaped path from the drum, under the idler pulley, and around the motor pulley.

Reinstall the bulkhead and blower pieces

Mount the bulkhead onto the chassis by engaging the top on the two chassis fingers, then maneuver it until it sits flat.
Align the bulkhead rollers with the front lip of the drum, and turn the drum while pushing the bottom of the bulkhead rearward if it won’t seat.
Use a 1/4 inch nut driver to install the four bulkhead screws, one in each corner.
Reinstall the blower housing cover and its screws in the positions used by your model.
Reconnect the moisture sensor harness to the bulkhead and chassis.
Feed the lip of the bottom latch bar into the blower housing, secure it to the bottom of the chassis, and install the screw into the rear of the blower assembly.

Reinstall the bracing and the front panel

Install the top bracing by latching the small metal fingers on each side into place.
Install the bracing screws on each side, including the front-side screws and the self-tapping screws at the top where the plastic bars are.
Thread the door switch harness back through the left side of the bulkhead to the rear of the dryer.
Hang and align the front panel on the small fingers of the bracing, and straighten bent fingers with needle-nose pliers if needed.
Install the top screws and the bottom screws underneath the dryer, tilting the dryer back if it helps you reach them safely.
Install the two Phillips screws at the bottom of the lint filter housing.

Reconnect wiring, reinstall the interface, and test

Reconnect the door switch harness to the control board.
Feed the interface wire through the front bracing and seat the interface into its slots.
Install the two screws securing the interface, one on each side.
Reconnect the interface harness to the control board and reinstall the press-mount cable tie.
Plug the dryer in and run a short test to confirm the noise is gone.

If the dryer turns quietly after you clean out debris and service the belt, rollers, and idler parts, the noise source was likely in that wear system rather than the motor. If noise remains after those repairs, recheck the blower housing and motor pulley area carefully before replacing additional parts. Repair didn't go as planned? Ask our Answers community for help.
