GE Microwave space saver

I saw your posting of your GE Microwave reseting back to setting clock/date/year after turning on for few seconds. What happen? Did you get it fix? How and what parts were replace? Or did you have to buy new one? Thanks for your time.

Sadly, we hear of this over and over.

This is usually due to a defective or loose magnetron causing electrical interference and disruption in the control circuit board.

If your magnetron was recently replaced, it may have loose mounting nuts or bolts or maybe the wire mesh RF gasket was not installed or got pinched.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

Details are in their bulletin here. Even if your model is not on the list, the same problem can occur, requiring a kit. The parts kit is similar to this one.

(Your model may use a different kit - this is shown for illustration purposes only).

If you or someone you know decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa.

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.

You can find helpful exploded view diagrams and order parts by entering your full model number here.

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.

Reset clock, ge spacemaker xl1800 times out after 2-3 seconds


There's a simple fix for this. Unplug the unit. Take off the top grill with 2 screws. Remove the 1 screw that holds the touch pad unit. Lift up on touchpad unit and lift out. Put a piece of aluminum foil inside a large zip lock bag and tape it to the back of the touchpad unit and reassemble. GE put the magnetron to close to the control board causing stray microwaves to interfere with the board. The foil shields it.

SET CLOCK. TRY TO USE. IT SHUTS OFF AFTER A FEW SECONDS.


I found an envelope with troubleshooting info inside the microwave on the left side behind the front vent. A troubleshooting flowchart was included which indicates that this problem is caused by the high voltage capacitor. I got mine out pretty easy and ordered one from appliancepartspros.com for $55 (which includes expedited shipping. I hope this info helps.

GE over the range space saver microwave


The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.

The microwave starts, then stops 2 seconds later


I tried a solution posted on another posting http://www.fixya.com/support/t242480-stops_cooking by placing the conductive plastic behind the control panel and it worked.

Shuts off, must reset clock


Sounds like you could have a fauly control circuit. Something like when you press the pad the processor does not interpret the information correctly and resets itself. Or the power going to this circuit is being interupted. It is VERY dangerous to work inside of a microwave. So you could get an estimate from a repair shop. But those control boards are expensive. Do not attempt to repair this yourself. For your own safety.
