Storage, trim and cosmetic hardware

Symptom: A cracked shelf, broken door bin, worn hinge, or missing trim piece -- cosmetic and storage wear rather than a functional breakdown.

Check: Match the physical dimensions and mounting tabs of the old part before ordering; these pieces are often model-specific even between visually similar models.

Drive system (belts, pulleys, motors)

Symptom: A drum or tub that won't turn, a burning-rubber smell, or a loud thump or squeal during a cycle.

Check: With power off, turn the drum or tub by hand -- resistance or grinding points to the motor or a bearing, and a cracked, glazed, or snapped belt is visible once the cabinet is open.

Parts in this group on 662: 7170700 (Lawn Tractor Transaxle Brake Actuator Arm), OEM7540439 (Belt), OEM7540440 (Drive Belt), 9111000 (Lawn Mower Belt Keeper).

Door and drum seals

Symptom: A door or drum seal that has lost its grip, letting water or conditioned air escape past it.

Check: Inspect the seal for tears, flattening, or gaps, and check it against your model's part number before ordering.

Parts in this group on 662: 36365 (Gasket).

Interior lighting

Symptom: The interior light doesn't turn on when the door opens.

Check: Confirm power is reaching the socket, then check the door-activated light switch before assuming the bulb itself is at fault.

Parts in this group on 662: 9250634 (Lawn Tractor Headlight Switch).

Before you buy

Match 662 exactly against the model and serial plate on the appliance itself before ordering anything — a single mismatched character can point to a different production run with different parts. Then check the part number printed or stamped on the part you are replacing against the part numbers in the table above; the printed number is the most reliable way to confirm fitment when a model has gone through multiple production runs. RepairKitHub does not sell parts directly — every part link above routes to an Amazon search for that part number so you can compare current listings and sellers yourself.

How to confirm this is your model

Check inside a door opening, on a back or side panel, or behind a removable panel or drawer for a label printed with the model and serial number. Match every character exactly, including letters and dashes at the end — appliance model numbers often have similar prefixes but different suffixes for different production runs.

Still not sure?

Use the model lookup tool to search by model or part number, or start from the symptom your appliance is showing.
