Turntable goes around when the door is open and the microwave is off.

You probably have a shorted main relay on your control board, which I can repair. Details here.

FixYa doesn't notify me when there's a response, so if you have other questions, please contact me directly.

Microwave Oven Control Panel Repair Nationwide
"Recycling by repairing since 1982"

This is usually caused by a defective door switch, or it may be out of aligment. Since there are a few of them a digital meter is required to troubleshoot the problem area. If you have the equipment I well describe how to test them.

The door open/close some microswitches. During the cooking process they became greasy and working bad. You must replace them or if you're a skilled man, wash them.

To access the door screws on MOST microwave ovens, you need to remove the inner door panel that goes around the perimeter of the glass. The following link explains:

This can be peroformed with the door in place, or with the door removed. If you have any questions, please post back with your complete model number and let me know. I hope this helps you.

the controller for the turntable is shorted out or welded its contact if its a relay. the door has safety switches that turns off the electrical connection to the turntable and magnetron once you open the door. you can trace the switch that runs the turntable. start from the power supply, goes to the door switch then to the controller before it goes to the turntable motor. i'm sure it has an electrical diagram at the inner wall of the cover.
i hope i was able to help.

Chances are that it is not actually microwaving, but that can be checked by placing a small cup of water inside.

Overall, though, it's not a good idea to run it if it's not working right.

This problem is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

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

There should also be a "mini-manual" hidden inside the unit behind the control panel, which is very helpful when troubleshooting.

If you think the problem is on the control panel, we repair these nationwide by mail for $39.95 postpaid in most cases.

Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. It's probably not actually heating with the door open, but better safe than sorry! If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number (without the suffix) here: http://tinyurl.com/gv383

What's happening is you are activating one door switch a little before the other, and that is causing your light, fan, and turntable to come on. The plastic parts are not perfectly rigid, so they flex a little when you press the button, and that causes the lag to be more apparent. Even if you press the door open faster and look really close, you may notice the light, fan, and turntable coming on for a split second. That's perfectly normal. The relay on the control board must also be turned on before it will actually be cooking.

If it jumps or moves just a little when you open the door, that is normal. It it actually runs, then you have a problem. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP button) is the primary cause of door switch failure.
