GE Built-In microwave and oven. The microwave will start, light comes on, but it does not heat and the turntable does not turn. Is it a faulty magnetron, or could it be a problem with a diode or fuse that would cause both the turntable to not work and and the microwave to not heat. I really need to repair. We have 7 children, so we really need our microwave working. Replacing the unit is not an option because it would be too costly. Your help is greatly appreciated.

bad primary door switch( usually little door switch at top). check ge website. i think there is a recall on the door switches for your model

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.

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.
