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

The interlocks are highlighted in the diagram below.

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:

(if it's not shorted or burned, it's probably okay)

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.
