If it is cooking with the door closed and the cooling fan is not on, the magnetron will be damaged or destroyed.
It may be a shorted cook relay on the control board.
Otherwise it may be a bad door switch or mount.

I have a Cuisinart cmw-100 microwave everything works except for the turntable. any suggestions?


Order a new turntable motor. Turn the microwave upside down and you can see the little door in the center where you can install it. Pretty easy, really.

Why is light staying on and its making annoying humming sound?


The door switches are either faulty or not being depress when the door is closed, this usually means that the door and the cabinet are out of alignment

Runs when door is closed,stops when open!Checked the three door switches;all good.The mw is 5 years old so anyone have suggestions as i would be thanking U in advance


It is possible that a relay on the control board has stuck in the closed position. You can try tapping the relays on the main control board and this sometimes breaks them free. It still may be one of the door switches but I would suspect the control board or possibly a stuck start pad on the touch panel.

Just purchased our Cuisinart Stainless Microwave, plugged it in, read the operational instructions and set the clock. As a test, we tried to heat water....does not work. Any suggestions?


Yes! Take it right back to the store for exchange, cause could be a bad magnetron "that heats food" and a couple parts that work together with the magnetron,or there may be issues with the keypad, none of these will be cheap to fix.

Possibly a shorted relay on the main timer board?? hum coming from transformer being powered with no fan running. With No fan you can hear it hum. shorted power relay on main board.

Kenmore microwave


i fixed by unplugging the microwave with the door open. I plugged it back in and the F6 was gone. I was then able to set the clock and turn the light on/off . When I closed the microwave door, the F6 came back on and the microwave was making a humming noise. I slapped the side of the microwave near the keypad, and the F6 cleared from the readout and the humming stopped. The microwave is working fine now. Don't know why, except maybe slap on the side reset a relay or something. Anyway, I will never by a Sears Kenmore appliance for the rest of my life. The door rattles when you open a close it (like a part inside the door is broken) and this is the second time a fault code has appeared during use. I had GE Profile appliances at my last house, which are more $$ initial cost, but who wants to screw around buying a new microwave every four or five years. I'll happily spend a couple hundred more for the peace of mind and knowing that it will work during Thanksgiving dinner with the family over.
