Electrolux microwave buzzes and food doesn't heat up


If the unit operates correctly except heating the food, then the unit needs a new magnetron.

My microwave doesnt work


If you hear an unusual buzzing noise, the magnetron (the component that actually generates the microwaves) or other electronic module may be broken. This is not easily fixed; contact a service technician.

Thanks,

micro

pls. rate..

The microwave no longer heats food and it smells as if something is burning. Everything else on the microwave works. Is this a common problem and how can I fix it?


Its your Magnatron tube, thats what makes the microwaves and heats the food. The part will cost you more than a new micro. The new model that replaced yours is a JVM1540 and you can get them for 179.00

Either the power board to supply the magnatron or the magnatron is defective.
Check or have someonr check the output of power supply. If ther is a hi reading, then change magnatron

My microwave starts however food does not heat up.


Micro wave as the name suggests produces heat when the micro waves aimed at an object causes the water molecules inside the object to vibrate hence producing heat.The gadget responsible is the magnetron. If your magnetron is not receiving ht voltage or receiving but faulty, then your micro wave wont work please take precaution when opening micro wave due to high voltage caps that remain charged sometimes even when it is off.check the high voltage fuse/ diode and capacitor if they are fine and the step up trans former o.k then the only option is to replace the magnetron

Micro wave stopped heating. All other features


Check the door safety interlock switches. Magnatrons are pretty tough but the little switches are not.

The microwave appears to be working but it is not heating up the food.


Several things can be wrong, 1st the diode which connects to the capacitor may be bad, the capacitor may be bad or the magnatron may be bad. Unless you are very very familiar with micro waves and high power I suggest a qualified appliance tech. Even with micro wave unplugged the high voltage area which all 3 of these components are can kill or cause serious injury. Sorry but do not feel comfortable telling you how to get to these for your own safety.

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.

Buzzing Microwave


the buzzing is the magnatron tube juicing too thousands of volts before emmitting the micro-wave radiation to what your cooking that turns molecules 180 degrees around... guess that friction is what really heats it.
radar ovens is what they use to call em and even people would stand in front of big ones to warm up long ago...lol canibles will love that.
