Hi there, I have a LG model: LMV1640DW1 microwave oven. Everything seems to be ok, but does not heat my food. The microwave is fairly new (feb 2008)


Possibly high voltage fuse or diode.If it is an inverter model may be circuit board problem.Not advisable to try and fix yourself very high voltage build up could still be present, contact your local repairer.

Everything works ok except strange hum and no heat


When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.
If it is under warranty you are golden. If not, you should get an estimate, as many new microwaves are now in the 50 dollar to 99 dollar range

Chances are you have shorted or blown high voltage rectifier diode.

Here is a link you or someone you know can use to test it, but please read the safety info:

Microwave will not heat food


Found this under Maytag instead of LG, but will be happy to help.

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, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

Magnetron diagnosis is here: http://gallawa.com/microtech/mag_test.html

We're happy to help and we appreciate your thoughtful rating of our answer.
