Microwave turned on by itself

My microwave turned on itself and when I turned it off It would not start, again. I do not know how long it was on. Could this start a fire, If I did not catch this in time? I am afraid to buy another magic chef .thanks

    Same problem. Magic Chef says it needs a new motherboard.

  • loridow1 Jan 04, 2009

    My Magic Chef is Model MCO 160UB, and is an "over the stove" model. This happens every time I boil anything on the stove, even though I use the microwave vent fan every time I cook anything on the stovetop. I purchased this microwave only a year ago, and it has been installed for only about 9 months. I keep a cup of water in the microwave just in case it turns itself on. This can happen even several hours after cooking is completed!

    This units manufacture date is July 2007.

Have you tried unplugging it than reapplying power ? Sometimes a power up reset will clear the logic on the control card and yes.. if it continues to run have a potential fire hazard...

Microwave turns on by itself

The problem is in the keypad control board, in order to fix this the part alone starts around $100.00 and must be replaced to fix this, also it would be a good idea to get the door switches checked.

Microwave is turning itself on

First, do not leave this machine plugged in until it is serviced. If this is a KHMS155LSS, there is a very high probability that you have a keypad short. This defect can cause the machine to start on its own at ANYTIME, at night, while you are away, at work etc. Contact Whirlpool Customer Service and ask for Safety Dept immediately. They will most likely send A&E out to fix it. Although it will fix the problem, if the keypad fails again, the self start logic defect is still present. You should be under warranty if it is above model. I almost had a fire this past Monday, Labor Day, 9/7/09 when my machine self started at 3 AM with a package of bacon left in to thaw for the morning. What a somey mess. Chinese made garbage.

Microwave turning on by itself

Sounds like a relay is stuck/activated by something. Causes are power surges, mice shorting wires, spiders and such creating bridges across the contacts on the circuit board. Not a DIY project unless you have some electronics background and know what precautions to take while inside the case. There is enough juice in there to seriously injure or kill a person. Eric

Microwave suddenly went off while I was cleaning the inside of it, and won't turn itself back on.

You should not have cleaned it. No just kidding. It was probably just a coincidence that the fuse failed at the same time. fuse's are all ways the first thing that go's . Try replacing the fuse. If you need help . let me know I will walk you througt it. DFD

Turns on by itself and turntable does not rotate

You may have a control board issue. Thank God for safety switches.
This is a problem that an integrated circuit tech. can repair, but it may be costly.
Decide how much you want to put into this oven vs. buying a new one.

Contact me once you decide and I can help you find a service center.

Thank you,
