A microwave door not opening is often caused by a bent or damaged door hook or latch or a broken door spring. For some models, these components can not be replaced separately and you will need to install a new door assembly to fix the problem.

Cause 5Switch Holder

The microwave switch holder is the component that houses the door switches behind the control panel. If the switch holder is damaged or misaligned, the door may have trouble opening.
