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.
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 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.
There's no heat, but it buzzes loudly When the microwave won't heat, but you hear a loud buzz, you usually have a defective power diode, high-voltage capacitor, or magnetron. You can get required parts from www.repairclinic.com
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

SOURCE: Microwave makes a loud noise while using.

After you turn it on, it's a loud noise like it's coming from the fan, but other then that it works wonderfully.

SOURCE: Microwave makes loud noise and does not heat. Smell of light burning

Chances are you have a bad magnetron.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

If you or someone you know 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.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

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.

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

SOURCE: Microwave making loud noise behind control pad and won't heat

Sounds like the magnatron (the bit that creates microwaves) could be goosed. Remove outer cover ( Isolate from the electric supply then remove screws at bottom on the sides).

Find big lump that says on magnatron with model nos etc on, any good electrical supply shop ( Maplins etc) should stock new one.

It is easy to change. It took me about half an hour having never done one before.

Buyer beware the price of the parts could be in excess of a new microwave.

Shop around

SOURCE: Danby microwave does not heat food and makes loud constant noise.

IF the noise is a sound coming from the oven area, its the megatron tube. Typically, replacing the megatron tube is more expensive than replacing wiht a new unit and a new warranty.

Microwave turns on when the door is open must un-plug to shut off


Is it actually heating or just making noise and acting like it's heating? (Put a cup of water inside and close the door.) IF it's actually heating, then you have a shorted relay on the main control board, and you will have to replace the board. IF it's just making noise like it's working, but it's not heating, then the problem is that one of the door switches is not working right (it's either stuck open or stuck closed).

Microwave won't heat


This is very likely a faulty Magnetron especially as there is not heat. To repair this would mean replacing the Magnetron which is a fairly standard repair for a Microwave oven

We were using the microwave the other night and it started making a loud noise like the fan was running (although the fan was not). We let it sit for awhile and try to use it again but the noise came...


The loud noise and no heat means that the magnetron has failed. It the part that generates the microwaves that heat the food. When it fails it shorts out, causing the transformer to heat up. That is what was causing the burning smell. The cost of a replacement magnetron is around $130-150 range so it may not make sense to have it fixed.

Microwave not heating and giving burnt plastic smell


STOP USING IT!! UNPLUG IT!! Microwaves are inexpensive now. It will cost you more than a new one costs, to get it fixed.

Noise while not running


don;t worry;
all you need to do is lubricate the fan bearings with light machine oil and make sure the fan is not hitting anything

Does microwave ovens make noise while it is in process of heating?


It seems like it is the first time you either own or using a microwave oven. Yes, there are more than one fan/motors inside a microwave, depending upon the model/type.

Microwave makes a loud noise while using.


Could you describe the noise?

It may be a noisy fan motor or a failing magnetron or high-voltage transformer.
