How do I fix Kenmore Dryer Idler Pulley Replacement - Signs & How-To?

Follow the step-by-step diagnosis below. The most likely fix is identified by checking power, sensor resistance, and control-board signals in order — using a multimeter and the part numbers documented in the parts reference table.

Can I keep running the equipment with this fault active?

Generally no. Faults on Appliance units are emitted when a sensor, safety, or control circuit is outside its operating envelope. Running through an active fault risks compressor, heater, or control-board damage. Diagnose and clear the fault first.

Is Kenmore Dryer Idler Pulley Replacement - Signs & How-To a DIY repair or do I need a technician?

Sensor swaps, fan motor replacements, and condenser cleaning are typical DIY-level repairs. Anything involving refrigerant, gas, or high-voltage (>240V) work requires a licensed technician for both safety and code-compliance reasons.

Kenmore Dryer Idler Pulley Replacement - Signs & How-To

Q: What does Kenmore Dryer Idler Pulley Replacement - Signs & How-To mean?

Squealing, squeaking, or no tumbling? A worn idler pulley loses belt tension. Replacing it restores smooth, quiet operation and proper drum spin.

Kenmore Dryer Idler Pulley Replacement — What This Part Does

The idler pulley is part of the belt-tension system in your Kenmore dryer. It keeps the drive belt tight around the drum and motor pulley so the drum can spin smoothly during the cycle. Over time, the pulley bearing wears out or the wheel itself becomes damaged from friction and heat.

When the pulley fails, it can no longer maintain correct belt tension. You will hear squealing or squeaking during operation, or the drum may stop tumbling altogether. Many techs replace the drive belt at the same time since both parts wear together and the dryer is already open.

Jump to Replacement Steps

Signs It Needs Replacing

Squealing or squeaking during the cycle A worn pulley wheel or bearing creates high-pitched noise as the belt moves over it.
Drum will not tumble or turns very slowly A seized or broken pulley cannot keep the belt tight, so the drum does not spin properly.
Dryer starts but clothes do not dry If the drum is not turning, air flows through but clothes stay wet because there is no tumbling action.
Visible wear or damage on the pulley wheel Inspect the pulley and you may see grooves, cracks, or a wheel that does not spin freely on its axle.
Belt slips off or appears loose Without correct tension from the idler pulley, the belt can wander or fall off the motor or drum pulleys.
Burning smell or hot pulley A binding pulley can overheat from friction and produce a burning odor during operation.

How to Replace It

Unplug the dryer from the wall outlet and wear work gloves for sharp edges.
Pull out the lint screen, remove the two screws inside the lint screen housing, then lift the top panel up and prop it open.
Remove the screws along the top edge of the front panel, release any clips at the bottom corners, and carefully lift the front panel off to expose the drum and belt system.
Take a photo of the belt routing around the drum, idler pulley, and motor pulley so you can match it during reassembly.
Push the idler pulley toward the motor to release tension, then slip the belt off the motor pulley and idler pulley and let the drum rest.
Remove the idler pulley from its mounting bracket or axle (some models use a tri-ring retainer or clip, others use a bolt or pin).
Install the new idler pulley on the bracket, then loop the belt around the drum with the ribbed side against the drum and route it through the idler pulley and motor pulley following your photo.
Rotate the drum by hand one full turn to confirm the belt tracks smoothly and is not twisted.
Reattach the front panel and top, replace all screws and clips, reinstall the lint screen, plug in the dryer, and run a short test cycle to verify quiet operation and proper tumbling.

The Part You Need

Part	Notes
Kenmore dryer idler pulley assembly	Amazon \| Check your model and serial number on the plate inside the door or on the back panel. Common OEM part numbers include W10837240 and 691366 depending on your model family. Some assemblies include the bracket and hardware.
Dryer drive belt	Amazon \| Inspect the belt for cracks, glazing, or fraying while the dryer is open. Many techs replace the belt at the same time as the idler pulley to avoid a second repair soon after.

When to Call a Pro

If you are not comfortable disassembling the front panel and routing the belt correctly, call a technician. Incorrect belt routing or a twisted belt will cause noise and poor drum rotation. If you find other worn components like a damaged drum roller, drum bearing, or motor pulley during the repair, a pro can replace the entire set in one visit and verify smooth operation before leaving.
