My GE Profile Microwave/Convection Oven stopped working.

Chances are that the thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.

This can happen when the magnetron overheats, either due to it's failing, or if the internal cooling fan is not working.

It may also that be the 15- or 20A ceramic line fuse or the oven cavity thermostat / thermal cutout / T.C.O. (whichever it uses) has opened.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.



At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

You can find helpful exploded view diagrams and order parts by entering your full model number from the tag on the oven here.

You should be able to get the fuse from a home center or local appliance parts store.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.
