With the symptoms you mention, I would suspect:

- loose or corroded connection at the magnetron
- bad magnetron
- shorted high voltage diode

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.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: My microwave does not heat anything. The touchpad, exahustfan, light works. The motor turns on and turn-table works for the number of mins specified but does not warm up the stuff. Please help!

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron 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 apart. It is a fairly lengthy process however.

SOURCE: whirlpool model number MH7140XFB no longer heats

you either need a new h.v. capacitor or h.v. diode in the magnetron circuitry if you cant hear it cycle when it runs as in a low pitched hummmm when its drawing current to operate the magnetron tube, each part runs about $30 to $45 each,normally its the h.v. capacitor though

SOURCE: Microwave runs but won't heat

No reset button, there's nothing to reset in it. If you don't get heat and everything else is working that means that the magnetron tube isn't working.
The tube doesn't work because either it's defective ir it isn't powered. To check which you must open the oven and test the power to the magnetron.
Beware, if you don't know how to do that safely or you don't have a very good voltmeter then don't touch it, the very high tension inside can easily kill you.

Microwave will not heat


hello,

what this mean it that your wave has develop a disconnection problem internally from the wire what you will have to do to fix up your wave is to unscrew your wave then trace the wire down to the element (heat provider) it is silver in colour
please if there is no disconnection in it then it means that the element has gone bad then you will have to make a change of it with a better one you can get it in the store
please make sure that all form of power supply is put OFF before you can carry out this function.

Good lock ,thank you and thanks for using fixya.

MICROWAVE NOT HEATING


I have the same problem. Everything seems to work except it doesn't heat up food.
I remember last time when it was working. I pressed the start botton before I closed the door. So it didn't start automatically, and I pushed start and it worked(it still heat up the food), but it doesn't work now. Help Please!!!
I have a Whirlpool Gold GH5184XPQ.

Thanks in advance
