Kenmore Microwave Not Heating Up Food

Lights timer display all work.

Kenmore microwave not heating up food. This high voltage powers the magnetron to heat the food. The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. If the voltage is normal then it s time to replace the magnetron with a new one. Once the voltage is normal the microwave oven will start to work fine.

The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. Easiest fix you can find. Br i have a kenmore microwave 790 83337710. This is the part that makes the heat to cook the food.

This high voltage powers the magnetron to heat the food. When the diode fails it is often visibly burned out. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating. When the voltage drops below 215 volts the microwave does not heat the food well enough.

My kenmore microwave is not heating. A new and better video update for the previous one where i explain how to fix your microwave that works but doesn t heat. A microwave that does not heat up may have a broken magnetron. When i push start it sounds like it working but the turntable doesn t move and it doesn t heat.

The easiest way to determine whether your microwave is failing is to try to heat a food item. If it is broken it may blow a fuse in your microwave which could lead to other components failing.
