Kenmore Microwave Not Heating Up Food

Easiest fix you can find.

Kenmore microwave not heating up food.

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. If it is broken it may blow a fuse in your microwave which could lead to other components failing. This is the part that makes the heat to cook the food.

The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts. My kenmore microwave is not heating. Lights timer display all work. How to test microwave magnetron with a multimeter.

Once the voltage is normal the microwave oven will start to work fine. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave. Br i have a kenmore microwave 790 83337710. When the voltage drops below 215 volts the microwave does not heat the food well enough.

This high voltage powers the magnetron to heat the food. If the voltage is normal then it s time to replace the magnetron with a new one. A new and better video update for the previous one where i explain how to fix your microwave that works but doesn t heat. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.

If the microwave doesn t heat or it heats more slowly than it should this indicates that it is. When the diode fails it is often visibly burned out.
