Check: With the appliance unplugged, check continuity across the part with a multimeter -- no continuity means it has failed.

Parts in this group on Z478-SU: 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.

Before you buy

Match Z478SU 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.
