Microwave starts by itself or will not stop

A microwave that heats on its own is a fire hazard: unplug it and do not use it. The usual cause is a stuck relay or shorted triac on the control. On OTR units, a fan that starts by itself is often normal heat protection, and a light that stays on can be moisture.

Microwave has display/clock but won't start

Rule out user settings first (control lock, demo mode, Start not pressed, shipping spacer). If those are fine, the control is not seeing a closed door or is not driving its relays: door switches, latch, or control board.

Microwave keeps blowing the line fuse when the door is opened or closed

The monitor switch is designed to short the line and blow the fuse if the door switches do not open in the right order. Worn latches, a misaligned door or a failed switch cause this. Replace the failed switch(es), check latch alignment, then replace the fuse with the exact rating.
