SOURCE: Microwave ahs power but doesn't heat.

The most common causes for a lack of heating are a bad door switch, a loose connection on the magnetron, a bad magnetron, bad connection on the control circuit board, a bad relay on the board, bad high voltage diode, or bad high voltage transformer.

This would be under warranty, so Maytag should take care of it for you: http://maytag.com/support/index.jsp

SOURCE: Microwave sedems to be working but not heating

This is usually a shorted high voltage rectifier diode or 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 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 may 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.

If not, here are some links you or someone you know can use for test help, but read their safety warnings first:

My Whirlpool microwave, over the stove, stopped working when my son used it to heat his food and a heavy sound came out, like something exploded in it. When I check it, there was nothing broke. Everything works fine except that it does not heat. I will appreciate any help

About 95% of the time it is the magnatron. If the microwave is under 5 years old that part is often covered under warranty. I would check your manual. If not the p/n is 8206335 and it's about $80 and fairly easy to install. I just looked and the magnatron is covered.

Labor to replace it would be about $125

I have a Whirlpool GH5176XPS microwave and everything seems to work fine except that it does not heat anything. I have checked all the fuses and they are fine. Any suggestions?


The problem is more than likely a bad magnetron, "heats food" the other two considerations are the high voltage capacitor and diode.

Our whirlpool microwave does not heat. Everything


Hi!if your microwave does not heat, it only means that the magnetron is not working, try to look for busted fuse. or check the capacitor for leak, the hi voltage diode sometimes malfunction, and if all of the above mentioned are all ok maybe your magnetron is defective.

Whirlpool Microwave no longer heating


Sounds like the magnetron has failed. It is the magnetron that generates the microwaves that heat the food. If it or the circuit that powers it fails then it stops heating. There are some high voltage circuits that feed the magnetron and you can potentially get hurt if you don't know what you are doing. Would recommend you have it serviced by a professional if you want it fixed, otherwise look for a new one since the cost of repair can come close to the price of a new microwave oven.

Power out on Whirlpool over-the-stove microwave


Yes, There are fuses inside the keyboard panel. I would have to take a look at the manual for the specific model you have to identify the easiest way to check the fuse.
Before you go that far check above the hood and see if you can locate the plug end of the microwave. Most installations have a dedicated receptacle above the exhaust vent and microwave. It is usually a space too small for good storage so most housewives store small items and cookbooks in this space. It is usually the culprit for a microwave suddenly going out without someone placing metal inside the oven and heating it.
Heating a metal object or operating a microwave for an extended time will usually blow the fuse.
