Microwave buttons not responding - microwave running constantly with door shut

The microwave is not supposed to shut off if you have food in it. it is designed to stay running so you will not forget your popcorn.

Missy Uhland Bauman,

I understand that you are hearing a buzzing noise from your microwave, even though the door is shut and and it is not running. I would suggest to give the appliance a hard reset. You will do this by either unplugging it or cutting the power off at the circuit breaker for 3-5 minutes. After the 3-5 minutes, bring power back. If you are still hearing a buzzing sound, I suggest either contacting the manufacturer or your local authorized technician.

-Best Regards-

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.
So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off.
Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if contact is not through the microwave will not work.

Now keeping clear of the microwave, switch on, use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

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!

it acts like your control board has a bad coupling capacitor,or solder joint,i wouldn't spend a lot on it

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.
That said, you can get free estimates on the cost of a repair but you should also consider a replacement which may be a better option for you.

What they do not tell you about over the stove microwaves is that they are constantly deteriorating due to the steam, oil, and other cooking fumes from the stove below. As a result, their life expectancy is definitely diminished.

The circuit board is faulty. It should be covered under the warranty. Call GE or the place of purchase.

I tried all the things on your website. Holding the clear button , unplugging,...

So I went back to the last operation that I was doing when the problem started.
I was using "reheat" so I put a glass of water in the micro turned on reheat 1 serving.
It started and then I hit clear after a few minutes and the problem went away.

Consult your manual, but it might be in demo mode. Unplug it for about 10 minutes to see if that would help.

Sounds like a defective door interlock switch or a broken switch mount. 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 model number here: http://tinyurl.com/gv383 If it's not a problem with the door switch or door switch mount, it may be a problem on the control board. We repair these for $39.95 for customers nationwide. Reply back if you still ned help.
