My microwave stopped heating. Everything else works fine. When press one of the heating options it rotates, light is on, etc, but food remains cold. I put a dish with gold trim to test - there were no sparks.

You're lucky! You could have ruined your plate with that test!

There should 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.

My microwave stopped heating. - dee77f7.jpg

At
our Web site, we have a video available showing how to remove a

typical over the range control panel assembly in under 5 minutes.


If you don't find your mini-manual, or if you want to look at it before removing the controller, you can likely download it here (just enter your model number).

Some questions to help you or someone you know troubleshoot it:

When you hit "Start" to microwave, do the inside light, cooling fan, and turntable all come on?

If not, then you probably have a bad door switch or door switch mount and should see these files:

http://www.microwavedisplay.com/safety.txt
http://www.microwavedisplay.com/disassembly.txt
http://www.microwavedisplay.com/doorsw.txt

If the inside light, cooling fan, and turntable are all coming on, then the problem is in the high voltage section, and then the next questions arise:

Any unusual noises? Is it louder or quieter than usual?

We have a sound clip of what a microwave should sound like when the cooling fan and high voltage section are operating here.

A loud buzz, hum, or groan is usually a shorted high voltage rectifier diode, but a sound like gurgling into an empty coffee mug is one symptom of a failed magnetron, and yet the mag can be bad without that sound.

If there's no unusual noise, it may just be a bad connection at the magnetron.

Here are some links you or someone you know can use (in order given) for high voltage section test help, but read the safety warnings first:


http://www.gallawa.com/microtech/diode.html
(if it is NOT shorted or burned looking, it's probably fine)


http://www.gallawa.com/microtech/mag_test.html
(continuity can be good even though mag is bad!)


http://www.gallawa.com/microtech/xformer.html

You can find links to helpful exploded view diagrams and part ordering help here.


I'd recommend that your bookmark this link to your favorites.


Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.


You can download owner's manuals and installation instructions for several brands (including Amana, Jenn-Air, Kitchenaid, Litton, Maytag, Roper, Tappan, Thermador and Whirlpool) here.

> Why has the plate stopped rotating?

The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

> Will the food be evenly heated even though the plate is not rotating?

No.

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

The microwave will not heat the food


Yes - please buy a new one.
Unfortunately microwaves have 2 positions - working or dead!.
The cost to resurrect from the dead is all out of proportion with the cost of buying a new one which will have at least a 12mths guarantee

Microwave turntable doesn't turn. Everything else


The turntable system typically consists of the motor, the coupler, the turntable support with rollers, and the tray.

Here is a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You can find links to helpful exploded view diagrams and part ordering help here.

But if you've recently had trouble with the cooktop lights, then the control board may be damaged.

We regularly repair these control units for customers nationwide by mail for $39.95 postpaid in about a week or so with a one-year guarantee.

Kenmore Microwave Won't Heat Food


The service manual is here.

Unless there's a bad connection at a magnetron terminal, I would say you have a failing magnetron.

It is part number 2B71165R and you can get it from the Pros here for $68.59 (subject to change).

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

Microwave not working


Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend 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: http://tinyurl.com/yzjozk
