Microwave stopped heating!

My GE XL1400 Spacesaver microwave has suddenly stopped heating.  It looks fine, and acts fine, yet it doesn't cook my food. 

There was no event to cause this - one day it worked, the next day it didn't.

I've tried several different foods, different settings etc.  I tried different power levels, different modes, turned on and off the child lock thing.

I've unplugged it, and plugged it back in.

All of this didn't fix it.  Help!

Re: Microwave stopped heating!

This may have already been dealt with, but others can benefit from an accurate, thoughtful reply to this problem.

Concerning the problem Guest is having with the fan coming on when the door is open.

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, linked here on Fixya:

Concerning the original problem of no 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

Re: Microwave stopped heating!

Sounds like there is a problem in the high voltage section.  If it isn't under warranty I would suggest buying a new microwave.  This will need to be checked by a technician with the proper tools.

May Spacemaker XL1800 stop heating food. Was working fine. Then just stop

Is this an over the stove type unit? I have had a few problems with my over the range spacesaver. I think the heat from cooking gets up into the microwave and damages it. The steam from me boiling things on the stove had mine quit heating and I purchased a new one. The parts to replace the faulty ones can be quite expensive over $150.00, so its better to purchase a new microwave.

Why would my microwave no longer heat or cook?

micro waves use a tube inside that generates micro waves and like a light bulb they eventually blow out. the tube is not considered replaceable and cheaper to just get new unit.
