General hardware and mounting parts

Storage, trim and cosmetic hardware

Door, lid switches and latches
Symptom: The appliance won't start, or stops, unless the lid or door is fully latched shut.
Check: Listen for an audible click when the lid or door closes. No click, or a visibly cracked plastic tab on the latch, points to this part.
Parts in this group on KMW-4: 87663 (Door Latch).
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 KMW-4: 87991 (GASKET, DOOR LEFT SIDE), 89903 (GASKET, INNER WINDOW).
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 KMW-4: 87998 (Timer-to).
Before you buy
Match KMW4 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
On most microwaves, the model and serial plate sits inside the door frame. 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.
