Get shopping advice from experts friends and the community. If the voltage is normal then it s time to replace the magnetron with a new one. This high voltage powers the magnetron to heat the food. I have a kenmore microwave 709 80333310 that i bought new and have used about two months.

Kenmore microwave model 721 80012401 it wont heat up food kenmore microwave model 721 80012401 it won t heat up food at all. When i push start it sounds like it working but the turntable doesn t move and it doesn t heat. The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. A microwave that does not heat up may have a broken magnetron.

Any idea what went wrong. Once the voltage is normal the microwave oven will start to work fine. What we have heard in the past is when the microwave starts door closed and timer started it then turns on with a noise clunk and then the food is heated but now that noise no longer happens and the food is still cold. The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts.
