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.

The microwave won't stop.


You probably have a bad door switch or door switch mount. See this file.

I have a 10 year old MH7130XE Whirlpool microwave oven. The oven and key pad both work, and the oven heats just fine. The problem is the oven begins running as soon as you open the door...without pushing...


I'm assuming you mis-typed and meant the oven begins running when you SHUT the door and stops when you OPEN the door. Please tell me this is what you meant! If the microwave oven runs with the door open, UPLUG IT IMMEDIATELY AND DO NOT USE IT!!!

If the oven begins running without pushing the start button then the controller is bad or the Start button is worn out and making contact without pushing it. (Most likely it is your controller.) Generally, it is not worth the cost to replace the controller on a 10 year old microwave. Probably time for a new one.

But if you want, you can call Whirlpool and see what they suggest at 800-253-1301.

If this was helpful, please select YES to the first two RATINGS questions. Good Luck!

Don't know how to turn off the turntable


Turntable usually automatically switch off. If it is continuosly running check the related relay driving circuit.

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


Do not run the microwave with the door open. You will be cooked. Sooner or later, if there are enough microwave ovens, (and there are), everything that can go wrong with them will, eventually. There are several interlocking safety systems built into every microwave so that they won't work with the door open. Yours may have failed. I've never come across one, but that doesn't mean it can't happen.
It may only have a fault making the fan and turntable operate, which can sound like it's working with the door open. Either way, get it checked or get a new one.
This assumes that the microwave isn't actually supposed to do what it is doing under normal conditions or current programming. Refer to manual/instructions if unsure.:::Spiceweasel.au

My microwave continues to run, (turntable and exhaust), when the door is opened.


all microwaves have 2 safety switches at least... but these are tied to a set of relays that turn it on, my bet is a sticking or stuck relay because you unplug it right and plug back in its not running?-relay ... if always runs driver transitors.

Microwave Oven Problem


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
