General hardware and mounting parts

Symptom: A small mechanical or mounting part has failed, cracked, or gone missing.

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 20057933: CR003 (Garage Door Opener Light Lens), GUAT303 (Garage Door Opener Light Socket and Bracket Assembly).

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.

Parts in this group on 20057933: GUAT309 (Garage Door Opener Logic Board Bracket), CR002 (Garage Door Opener Motor Cover), GUAT327 (Garage Door Opener Sprocket Cover), GUAT022 (Garage Door Opener Door Bracket), RP008 (Garage Door Opener Hardware Bag and Emergency Release Handle), RP009 (Garage Door Opener Hanging Bracket), RP007 (Garage Door Opener Header Bracket).

Controls, timers and wiring

Symptom: A cycle that doesn't advance, an unresponsive display, or the unit not starting at all.

Check: Look for burn marks or a burnt smell near the board or terminals, and check whether buttons and knobs respond -- a unit that powers on but won't cycle often traces back to this group.

Parts in this group on 20057933: GUAT306 (Garage Door Opener Capacitor Bracket), GUAT305 (Garage Door Opener Motor Start Capacitor).

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 20057933: GUT840 (Garage Door Opener Chain Idler Pulley).

Before you buy

Match 20057933 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.
