i have a ge 1800 model and it cooks fine but after awhile it shuts down and in about a hour it comes back on and ask you to set the clock.....

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

check fuse inside unit microwave has a fuse around 15 to 25 amps get at local hard ware store u should discharge capacitor before installing fuse not nessary in microwave

if there is no plate to unscrew in front of the bulb , then the only way it can be changed is to open the microwave
WARNING: HIGH VOLTAGE CAPACITOR INSIDE WILL STILL BE HOLDING HIGH VOLTAGE
if you are not familiar with this then don't attempt the repair!
then you will need a technician

electech

lights underneath will not turn off

I had the same problem. I removed the grill and opened the control panel as I read an answer from "GENE" on APP (Appliance Pros) that this indicated a short in the circuit board (TouchPad). I was going to replace the faulty circuit board but when I opened the control panel there it was......One wire harness had just came unplugged!! I plugged it in, reassembled and the microwave works again!
