That would be a problem with your primary interlock switch or its mount.

NOTE: 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.

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: http://tinyurl.com/yzjozk

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours 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 may have to cut the cover off with snips, then use a screw when reassembling it.

With the symptoms you mention, I would suspect:

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

With the symptoms you have, I would most strongly suspect a shorted high voltage rectifier diode or a bad magnetron, or a loose and possibly corroded connection on the magnetron's terminal.

The diode is a fairly cheap fix, and your magnetron is still under the part warranty, but you would have to pay labor.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

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.

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

http://www.gallawa.com/microtech/diode.html
(if it's not shorted or burned, it's probably okay)


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

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

If nothing else, you can save about $50-75 if you remove it from the wall and take it to a Whirlpool-authorized servicer.

You can find your nearest Whirlpool/Maytag-authorized servicer here.

Accessing some components for testing and possible replacement will require you to remove the oven from the wall.

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 Whirlpool owner's manuals and installation instructions here.

This is usually caused by either a bad door switch or a loose door switch mount, which are pretty simple problems to fix.

Even though a door switch clicks, it may still be bad inside.

Door switch or mount trouble is usually caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

There are plastic mounts inside the microwave which hold the door switches and onto which the door latches lock when you close the door.

The screws on these mounts may be loose. If they get too loose, the switches will not be activated properly.

Sometimes it's a broken tab on the switch holder, allowing the switch to rotate just out of position. This tab can be hard to see, since it is under the bottom edge of the switch.

If the switch mount is broken, it's usually more economical and safer to add a dab or two of hot glue to the mount to secure the switch. Let it cool for about 30 minutes before using.

One test that sometimes helps is to gently lift up (and/or push down) on the door or handle as you try to start it. If it works or tries to work, then it's a door switch mount or door alignment issue.

Whirlpool microwave/wall oven model # GMC275PDQ3 not working


see this steps and use the common sense NOT feared: unppluged the power cord:
Lights come on, but can not program unit, Touchpad dead If you have a stuck key or non-responsive key, most of the time you will have to replace the keypad for this microwave oven repair. If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.
If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control. Most of the time, it is the keypad that needs replacing, but a small percentage of the time it can be the control. Check the tech sheet if they can point you to the right part.
God bless you

Microwave won't heat anything


take the cover off the machine and look for a 13amp fuse that supplys the tranformers. BEWARE!!!
when you open the machine disconnect from the mains and do not touch the high power circuits the capacitors can hold a charge that can kill.
