Before you order — 1-minute compatibility check

Unplug your microwave, remove the glass tray and roller ring, and check the label on your old motor. Match: voltage — this is a 21V motor (21V and 220V versions are not interchangeable), shaft shape and height, and mounting hole spacing. If your label differs or is unreadable, send us a photo before ordering — we'll confirm the right part.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
