Re: microwave resets when started

Could you explain what you mean by "resets similar to power cycle after 2 seconds of running"? Do the characters on the display get garbled, or is it like someone just unplugged the oven and plugged it back in? GE had a rash of "underperforming" magnetrons on several models. They would sometimes end up with stirrer damage, bad diodes, waveguide damage, and/or interference which "scrambles the brains" of the unit and makes them reset like they had been unplugged. The usual fix is to replace the magnetron, stirrer and high-voltage diode as a kit, and they used to cover this, but may not any more. Sometimes the unit gets run too long in a failing state and the waveguide and chassis of the oven get damaged. In that case, the oven would have to be replaced. To get the details and see if yours is affected, see this bulletin: Even if your exact unit is not on the list, you may have this problem. You can contact GE Customer Relations at 1-800-386-1215 and tell them your problem and they will put you in touch with a local authorized servicer. Feel free to post back if you need more info. I appreciate your thoughtful rating of my answer.

As soon as I start the cooking cycle, it shuts off with ****** in the display. We have been able to reset the time and date to get it going again, but now that does not work. We recently had new cabinets...

It sounds like a magnetron failure. This link describes a test to see if your magnetron is failing. Please be sure to read the comments near the bottom of the page!

GE spacemaker Power goes off and clock needs resetting

Try going to the breaker box and shutting off the power to the microwave for 10 minutes. After 10 minutes, turn back on and set the clock. This fixed my clock and turntable both. Apparently turning off the power resets the software in the clock.

Microwave was working fine but just stopped this morning. Is there a way that I can replace the high voltage fuse? Is it located in the panel inside the microwave?

You have not mentioned the make and model. Any way you can check the AC fuse on the power board inside the oven. If it is blown off you can replace it by a similar one, around 10amps fuse.
