Est the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

The turn table motor of your microwave is defective already and also the magnetron - the source of generated heat of the microwave is also defective. But before assuming that magnetron is dead, check the high voltage fuse it may be blown and replace the fuse (if it is blown) it with similar rating. I hope I help you with your microwave problem.

The food is safe as long as the food has not got oxidized aluminium on it.
Microwave energy is very high and will melt metals!
As long as it is not arcing any more there should be no problem.

My ifb microwave oven is getting hot outside while


Normally when u cook food in microwave the fod is cooked by microwaves, which means the heat is generated with in food. The temperature inside is never too hot and all the heat produced is absorbed with in the food.

On the other hand when the grill is switched on, a separate heatting element gets switched on. You can see this red hot element on the top side of inside of microwave. the heat from this element gets transferred to food through air circulation. But partof heat also gets transferred to the walls of microwave oven. This is the reason the wall feel hot during use of grill.

As i see ther is no problem with the microwave itself. Jut kep delicate thngs a bit away from the microwave.

Microwave will not heat any thing.


the plate has nothing to do with the microwave heating up the food
but the magnetron that heat the food is bad and will need replacing
I would ask a electronic shop how much they would charge to replace it , and if is not worth it to you then a new one would be a good call
