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.

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.

Before you buy

Match 3550 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.
