Kenmore Microwave Not Heating Up Food

Once the voltage is normal the microwave oven will start to work fine.

Kenmore microwave not heating up 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. 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.

If the microwave doesn t heat or it heats more slowly than it should this indicates that it is. When the voltage drops below 215 volts the microwave does not heat the food well enough. Br i have a kenmore microwave 790 83337710. This is the part that makes the heat to cook the food.

If the voltage is normal then it s time to replace the magnetron with a new one. Lights timer display all work. This high voltage powers the magnetron to heat the food. If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.

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. When i push start it sounds like it working but the turntable doesn t move and it doesn t heat. If it is broken it may blow a fuse in your microwave which could lead to other components failing.

This high voltage powers the magnetron to heat the food. The easiest way to determine whether your microwave is failing is to try to heat a food item.
