Heat control (thermostats, fuses, heating element)
Symptom: The appliance runs but heats or cools inconsistently, or shuts off partway through a cycle.
Check: With the appliance unplugged, check continuity across the part with a multimeter -- no continuity means it has failed.
Parts in this group on 478-SUB: 95111190 (Craftsman Heater Box).
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.

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.

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 478-SUB: 95110639A (MTD Lawn and Garden Equipment Engine Carburetor Primer Bulb).
Before you buy
Match 478SUB 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.
