First,make sure your microwave is plugged in and getting an ample supply of power. If the power is on,but it does not work check to make sure the door closes and aligns properly.Microwave door switches have metal terminals on the end that make contact with the door hook or latch.This completes the circuit which allows the microwave oven to run and without this contact the microwave will not operate.A simple misalignment might be breaking the circuit causing the microwave not to operate.If you suspect that the thermal fuse has blown,call a professional appliance repair person.If your microwave buzzes or hums but does not produce any heat,it could be a faulty defective diode,triode,high-voltage capacitor,or even a faulty magnetron.
However,this problem usually means a bad means a bad magnetron,followed by a bad diode.

Sharp 1200w microwave seems to be tripping lightly (can hear clicking noises)and cause heating to be irregular


Clean the food off the inside top of the microwave Now,Or that noise you are hear will stop along with the microwave. The food gets on the Formica Squire which is how the micro waves heat your food. 1st unplug the Microwave then spray the inside of the unit with something like Fantastic or something strong and use glove so you don't burn you hand,Also if you have a scrub brush use it,And clean all the soap out and raise very well.

The microwave does not heat up the food but everything works except the fact that it don't heat up the food


Hi!

The most common cause of the problem you described is a burned fuse. It is normally located inside the case, directly on a wire leading from the transformator to the magnetron. If you are not sure about those parts, please get a professional to fix the issue.

Good luck!

Mm5165bas, light comes on, fan works,carousel doesn't work , does not heat.


Hi, it sounds like the magnatron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnatron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnatron, they replace the whole oven.

There is a possiblity that the circuit that provides power to the magnatron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it appart. It is a fairly lengthy process however.

Everything works but it will not heat food


Check the door safety interlock micro switches. Others will po9int to the very expensive magnetron and it might be that but I don't think so. Still others will tell you that it is the capacitor ... and it might be that. If you regularly open the door while the oven is operating, the tiny contacts become damaged from the arcing. When the interlock switches can not longer tell the oven the door is in fact closed, the magnetron will not come on .. and there will be no heat.

It is probably worth removing the cover to check the $2.99 micro switches ...

Make sense?

Thanks for your question @ FixYa.com

the smoke probably came from the heated food. try using it next time with different kind of foods and also try it to the same kind of food that produces smoke but observe carefully what will happen.
