My lg microwave is not heating food everything seems to be working fine

SOURCE: microwave will not heat

Had the same problem--the timer would even count down. The magnetron fan would not turn on, and the microwave would not heat. Checked out several components, but ended up being just the door latch out of adjustment! Be sure to discharge the capacitor before messing around in there. It keeps a charge even when unplugged. Short out the unused terminal on the capacitor to a screw in the chassis, using a short length of insulated wire.

This is usually caused by a bad door switch or loose door switch mount but other common causes of a failure to heat are:

- 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

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help
