If it's cooking okay, and the turntable comes on when you cook, then it may be a shorted relay on the control board.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

Microwave door shut, but interior light is on - micro won't work

Yes. One of your door switches is not working. It could be an alignment issue or a faulty switch. There are actually 3 switches in the door latch area.

Light fails to operate with door open

If the light comes on during cooking then the bulb is ok.. in all probability the problem is the door switch that senses when teh door is open and activates the light... Hope that helps..

Interior light does not go on

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

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.

If you someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:

If you think the problem is on the control panel, which we repair these nationwide for $39.95 postpaid.
