Which part fits your microwave?
The model number is on a sticker inside the door, behind the kick plate, or on the back. Everything below depends on it — which part fits, what it costs today, and whether the repair is worth doing at all.
What actually fails on a microwave

Try the free check first
Every documented failure we hold for a microwave has a check that costs nothing, and it comes before any part. Some of them are the whole fix:
- Wipe down the latch hooks and strike plate — food residue there stops the door seating fully and mimics a bad switch.
- Test the outlet and breaker before assuming the fuse itself is blown.
- Clean around the button and lever pivot — grease buildup is the most common cause of a sticky latch.
- Make sure the tray and roller ring are seated correctly and nothing is wedged underneath — a jammed tray gets mistaken for a dead motor constantly.
- Just look at the coupler and tray notches first — this is usually a five-dollar plastic part, not a motor problem.
Is it worth fixing?
Often not, on price alone — but the documented failures are cheap enough that it is worth knowing which part it is before deciding.
