Won't heat food

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.


This is a job for a professional but if you are safety clued up, here's instruction.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 or moving coil meter on high resistance range for short circuit, (DVM's won't show the fault!), the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Load test.

A simple safety test.
Place 1/2 litre of water in a glass container. Measure the temperature of the water.
Place in microwave and heat on full power for 1minute.
Measure the temperature after it has stood for 1minute.
If the temperature difference is more than 9 degrees Celcuis the magnetron is working and producing about 700Watts of heat.
If your microwave is labelled with 900 or 1000Watts. That is about right.
If the temperature is less then the magnetron is not working properly and may need replacing.

This a only a rough guide and any doubts you should consult an authorised service agent.

How do you change the


The fuse is located on the power board inside the microwave oven. To get to the power board, trace the AC wire that connects from the wall into the Microwave. The going from the wall into the microwave is going straight into the power board.

So, to get to the fuse, you need to turn of the microwave and remove it from the wall. Get a screw driver, unscrew the screws on the oven and you will see the power board.

Also, if the plug entering into the wall is a three pin plug, then there should be a fuse on the plug. You might check that as well.

Lastly, read my tips on the below link about oven repairs, it might be of help now or later;


Good luck.

My Sunbeam microwave stopped work 1 min into cooking something?

There could be a problem with your microwaves switchboard.Or the wiring connection is not good and causes it to heat up and causes the fuse to trip and then has the power shut off for your microwave.
