Having a microwave not heating food up can be very frustrating.
What causes microwave not to heat food.
The easiest way to determine whether your microwave is failing is to try to heat a food item.
Possible causes of why a microwave stopped heating.
This is the part that makes the heat to cook the food.
How to test microwave magnetron with a multimeter.
For safety reasons we offer no do it yourself repair advice on microwave ovens due to an internal high voltage capacitor can hold a high voltage charge even after it has been unplugged.
The microwave door switch does not work.
The doubler breakage capacitor.
Humidity or moisture in the oven will lessen the sensor cooking time.
Too many dishes in the oven at the same time.
They actually start with the outer layers while the inner layers are mostly heated and cooked simply by transference of heat from the outer layers.
If the diode burns out the magnetron won t receive enough voltage to operate preventing the microwave from heating.
High voltage diode helps to power the magnetron and is located in the cabinet.
I removed the outer cover shorted the super capacitor so i wouldn t get zapped and proceeded to investigate.
Food not turned or stirred as called for in the recipe.
Make sure die inside of the oven and the outside of the containers are dry.
To check whether this is really the issue and to solve it you need to unplug the microwave and then discharge the high voltage capacitor.
A microwave not heating food properly is a common problem for many people.
The most common reason for microwave not heating could be problem with high voltage diode.
While microwave cooking does begin within the molecules where water is present they don t actually cook from the inside out like many people believe.
I received a microwave to repair and resell a few months ago with the identical problem.
Turn or stir food and begin again.
Do not overload your microwave oven.
The fuse on the transformer is faulty.
High voltage fuse in the box is damaged.
Everything worked except that it refused to heat so the problem was obviously not the ceramic fuse s hidden inside microwave ovens.
The uneven heating occurs because microwaves work with whatever water molecules are present and since not all areas of food contain the same amount of water heating becomes uneven.
The doubler is damaged diode.
Special equipment is generally needed to make a diagnosis if the above suggestions do not solve the problem and the microwave still won t heat we recommend contacting service.
The transformer does not send voltage to control panel.
This high voltage powers the magnetron to heat the food.
If the microwave doesn t heat or it heats more slowly than it should this indicates that it is.
Find out what the 5 main causes are for a microwave not heating food and discover some simple solutions to fix the problem.
The diode converts the a c power output of the transformer to d c doubling the voltage to nearly 5 000 volts.
The electric fuse has burnt.
