Won't heat up

Noise levels can be lower if you have an open component in the high voltage circuit (magnetron, capacitor, rectifier), or have a failure of the relay that powers that circuit. Also, there are some ovens which will seem to run normally, but fail to heat, due to a bad door switch.

Nearly (maybe all) small appliances with a heating element are equipped with a thermal fuse. This prevents the meltdown of heating elements, most of which are encased in aluminum. These fuses are not only unreliable (China is the biggest supplier) but generally unavailable as replacement parts since they are most often spot-welded to the ends of the heating element and would have to be replaced in the same way since solder melts at a much lower temperature.
I would suggest you replace the pot.

change magnatron fuse its in a plastic casing make sure it correct fuse .

Replace the capacitor and the resistor that attaches to the capacitor and it will work.
May have been the only problem to start with.

I would first suggest that you check the door switches.

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.

If you only need a switch, you can order a universal type here for $5 postpaid.

Especially if your cooktop lights recently went bad, you may have a problem with your control circuit board.

You can order one here, or we can repair yours for $39.95 in most cases.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Check the door safety interlock switches. Remove the cover to find these small micro switches on the side away from the hinges.

thanks for using FixYa.com

My GE doesn't have a Demo mode but say we have a power failure. It won't let me use it until I set the clock.

Try that and see if it helps

Yes it just will not cook or defrost very evenly. It is not dangerous however.

Probably the motor or gears that make the turntable go are worn or burnt out.

The hard reset worked....thanks a million

In most cases, you press Clock, enter the numbers for the time, then press Clock again, or possibly press Start.

Sometimes you have to press Clock, Clear numbers, then Clock or Start.

Or Clear, Clock, numbers, then Clock or Start.

In some older models, they had a very small mechanical clock button located at the top right corner of the controller near the display window. If yours has that, press it, then the numbers, then that button again or Start.

If this doesn't do it for you, could you post a clear photo of your control panel?
