Genuine GE Replacement Part

This thermal cut-off (part number WB21X10149) is for microwaves.

Thermal cut-off is a safety device that shuts off the microwave if it overheats.

Because high-voltage capacitors in a microwave can retain a lethal electrical charge even when the microwave is unplugged, a service technician should install this part.
