Spacesaver micro not heating

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and

I have a spacesaver profile and after 4 1/2 years the magnatron went out. magnatron has a 5 year warranty so it was replace,But I had to pay for labor. 1 1/2 later it went out again. haven't replaced it yet. had a friend buy the same one at around the same time and the exact thing happened to them. I'm trying to find out if this a recall or if GE will stand behind there product. lets face it the time a microwave gets used at minutes at a time it really isn't much

Had the same problem with GE Spacemaker XL1400 and successfully replaced the HV diode (~$20). These HV diode are solder heat sensitive and do get damaged easily.

Your magnetron, HV diode, Capacitor, or control board maybe bad most of these components run with high voltage and difficult to test without the proper equipment
