Microwave turns on when the door is open must un-plug to shut off

It's the bacon... it's holding the door shut

Likely when you cleaned it, grease mixed with the cleaner you used got between the button panel and the actual button switch behind the panel, making it stick on. Will need the model to determine how to remove the panel to clean underneath...OR, it may dry out and start working normally again.

The microwave should have lasted at least 5 years, Oster has demonstrated that profit comes first and the customer last.

One of the door switches is defective, caused by a build up of food particles or normal ware, to correct this a professional will need to identify the problem and replace it.

It may be a bad door switch or mount, or maybe a relay on the control board is sticking.

First, see our safety info here.

Then we have a helpful file on diagnosing and replacing door switches here.

If that's not the issue, we regularly repair control circuit boards for $39.95, or you can order a new one (part number 8205237) for $203.08 here.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

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!

Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

The turntable is a seperate intenty from the microwave itself, I would presume that the switch that turns off the turntable when the door is opened needs replacement.

MICROWAVES ARE MADE TO BLOW THE FUSE IF THERE IS A POSSIBLY OF DANGER--THAT'S A GOOD THING...SAFTY SWITCHES ARE MADE TO CLOSE(SOME UN-CLOSE) WHEN THE DOOR IS OPEN AND SHUT AND IT SOUNDS LIKE YOU DO HAVE A LITTLE DOOR PROBLEM---THE REPAIR SHOULD BE FIXABLE AND MAYBE REASONABLE,,MY GUESS COST-WISE ,,,75.00,,OF COURSE ,IT ALL DEPENDS ON THE SERVICE COMPANY--TRY AN INDEPENDANT SERVICER (NOT SEARS,ETC) GOOD LUCK TUNICA

Sounds just like a bad door switch or door switch mount. Probably the upper one. Safety info, disassembly tips, and door switch test and replacement info are all available at our Web site. See http://tinyurl.com/yzjozk
