I would suspect a shorted high voltage rectifier diode or a bad magnetron.

Here are some links you or someone you know can use (in order given) for test help, but read the safety warnings first:

http://www.gallawa.com/microtech/diode.html
http://www.gallawa.com/microtech/mag_test.html
http://www.gallawa.com/microtech/xformer.html

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Boiling waer under micro wave lots of steam into micro wave, turn on micro wave ,pop noise like glass miro wave comes on louder hum than normal no heat


Q - The microwave display counts down and the inside light is on,  but nothing is heating and the fan is not running.
A - This most commonly is a bad door switch, other possible problems are a faulty relay or solder joint on the power module, but a bad door switch is most common.
 Q - My microwave is running and sounds like it is working but will not heat up anything.
A - Many thing can do this but, common things are....loose high voltage wire.....poor solder joint on board.....magnetron.....power relay.....
Q - The microwave makes a loud "hum or buzz" noise but will not heat up the food?
A - 9 times out of 10 this is usually this is a bad magnetron, the other time is sometimes a bad high voltage diode. See components section.

My micro wave will not heat products. All other systems are functional.


Do the inside light and turntable come on when you try to cook?

Is it making any unusual noise or is it louder or quieter than normal?

Do you have the model number?

Heard a loud glass breaking noise, now micro-wave will not heat anything. Turntable works, everything looks fine but no heating. Model#R-1505LK


Does it seems to run louder?

I would suspect a shorted high voltage rectifier diode.

We have the full service manual and have uploaded it to our site here.
