When the diode fails it is often visibly burned out.
Kenmore microwave not heating up food.
This high voltage powers the magnetron to heat the food.
Lights timer display all work.
The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts.
When the voltage drops below 215 volts the microwave does not heat the food well enough.
If it is broken it may blow a fuse in your microwave which could lead to other components failing.
The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts.
If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.
When i push start it sounds like it working but the turntable doesn t move and it doesn t heat.
My kenmore microwave is not heating.
This high voltage powers the magnetron to heat the food.
A microwave that does not heat up may have a broken magnetron.
The easiest way to determine whether your microwave is failing is to try to heat a food item.
This is the part that makes the heat to cook the food.
Br i have a kenmore microwave 790 83337710.
If the voltage is normal then it s time to replace the magnetron with a new one.
Easiest fix you can find.
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 microwave doesn t heat or it heats more slowly than it should this indicates that it is.
