Microwave ovens are so quick and efficient that they channel the heat energy directly to food molecules.
Microwave not heating food is a common problem. There are many reasons behind this issue. In order to know your microwave better, it is very important to understand these reasons.
Diode burn
Your microwave has some very important parts called diode and magnetron. The diode converts incoming A/C power to high voltage D/C. This high voltage is used to provide energy to magnetron which in return emits heat energy to cook food. So when the diode fails or burns, magnetron does not get power to emit heat energy to cook food.
Magnetron Failure
If microwave does not heat food, then the magnetron might have burned out. A magnetron uses high voltage to produce microwave frequency to cook food. If the microwave is turned on when it is empty, this cause the magnetron to burn out. A burned magnetron has to be replaced as it cannot be repaired.
Faulty door switches
Microwaves normally have 3 door switches. When either of the door switches go bad, microwave does not turn on and does not heat food.
Faulty capacitor
The capacitor works with the diode to convert the A/C power to D/C voltage. If the capacitor is burned out, the entire high voltage circuit stops working. As a result the magnetron cannot be powered. A powerless magnetron cannot emit heat to cook food.
Faulty Transformer
When the transformer burns, the process of converting A/C power to D/C does not start. As a consequence magnetron could not be powered and a powerless magnetron cannot emit heat to cook food.
The article has some technical details which might be difficult to understand. So the take away of this article is that the magnetron is the heart of the microwave system.
If the magnetron does not get energy supply or if it fails, microwave stops heating food.
