Question about Microwave Ovens

1 Answer

Turns On by itself

My over the range microwave turns on by itself. Light comes on and it starts making sound as if some part is running. I tried to see if it heats up water, it doesn't.

I have to play with the door to get the motor (or whatever is running) to stop and the light to go off. Then I can use it.

I am trying to decide whether it is a cheap and easy fix or should I just buy another unit. This microwave has another problem - the turn table doesn't work. If I take the turn table off, I can see the motor is turning (very slowly though), but it doesn't even move with the weight on it.

Replace it. I work in sales for Whirlpool. It sounds like the door switch is either sticking or shorted. Also because your turntable continues to run it sounds like a short. Microwaves are a unit we only recommend an authorized technician to work on due to the microwaves it uses.

The cost of a new one is usually easily half or more the cost of repairing it.

Average service call just to give you an estimate is 80-90$

Why won't my interior microwave light turn off and my microwave won't start?


It sounds to me that your door switches aren't working.Your oven is protected by a couple of switches that engage when you open or close the door.They control a couple of safety features and also your interior light.One of them seems defective.

Have Kenmore microvave and the vent starts on its own


Actually, that's a feature! If you cook much on the range (stove) beneath the microwave, the heat will cause the microwave bottom to heat up quite a bit (just touch it!), and the microwave will turn on it's exhaust fan in an attempt to save itself from burning up. It will shut off in about 15 minutes after you turn off the source of heat.
But if the fan comes on by itself even when the microwave is cool (or at least not hot), then you probably have a defective fan thermostat. This thermostat is located behind the control console on the inside bottom of the microwave.

Microwave starts by itself


Likely a microprocessor/control panel issue. Microwave ovens that sit over ranges often have electronic failures due to heat, humidity, and grease, from the range below, which come into contact with their main circuit boards.

My LG over the range microwave makes a rattling noise when I am cooking. The sound is not there is the item I am microwaving is heavy.


This may sound a bit nuts, but remove the glass tray and support ring. Clean the wheels and ring. Also clean the glass and microwave surface where the wheels run. Any tiny bit of debris will stop the wheels from turning, and make a rattling noise.
If that doesn't help, you may need a new turntable motor.

GE Microwave Profile Spacemaker Runs on its own


Your microwave turning on by itself is a "self preservation feature" of the GE Profile Advantium and maybe some other models. Read the manual, When your over the range oven gets warm enough, for whatever reason the venting fan comes on until a satisfactory oven temperature is reached. You are not permitted to shut the vent fan off. Also it seems a temperature near room temp must be achieved before it shuts the fan motor off, it is very annoying. We had to return our Advantium because of fan noise. I configured the ovens vent fan to the recirculate direction because we do not have a vent duct that exits the house over our range. When the vent fan acting as the ovens cooling fan automatically turned on we would have to leave the house to hear each other talk. Too bad we really liked the oven other than that major problem.

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,
