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 connection 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 disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

I have a Kenmore Microwave Model #721.80522500 that simply does not heat anything. Everything seems to work except that it doesn't heat anything at all.

Magneto or magnatron has gone bad. This is the part that sends the waves through the food to heat it.

no, just 1 main fuse for everything. there are temp safety devices though, and door closed safety switches. Most likely failure though is the magnatron.
