Question about Microwave Ovens
This is usually caused by either a bad door switch or a loose door switch mount.
Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.
Door switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.
