    Dear FixYa Team,

    First of all thanks for responding.

    Everything seems to work normal so light on, turnable turns no unusual noises.

    The only remarkeble thing it did in the past, for over one and a half year ago, I replaced in the main power supply a 16 AMP class C automat instead of a 16 AMP B class automat because sometimes when we starts up the microwawe before the automat shut down. After I replaced it we never hat that problem again.

    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises?

    Is it louder or quieter than usual?

I would say you have a problem in the high voltage section, such as a loose or corroded connection at the magnetron or a bad magnetron.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

It is a Daewoo MicrowaveThe microwave does not heat up the food! It is only about 18 months.Tried to to re_set but nothing happens as the food remains frozen or cold!Anybody has any suggestions?

There are three parts that could be bad. One is a high voltage diode, another is a capacitor and the third is the magnetron itself. If you are not familiar with these terms, it is time for a new microwave oven.

Maybe time for a new one. But just in case check the power outlet still has power and the circuit breaker is not tripped.

I have daewoo microwave conventional oven, heating problem because I was put inside milk for heating with polished pot, that is why microwave system is not working. do the favour for repair & guidance...

The feedback from the metal in the pot has caused some of the microwave parts to burn out. This could be an expensive repair and it involves checking the parts with a service meter. If you are not capable of doing that, then you need to have it repaired or replaced.

Convection function not heating from underneath

Sounds like the magnetron has failed. This is the component that produces the microwaves that heats the food.

The cost of the magnetron is about 95% of the cost of a microwave oven. Most people don't, for this reason, replace the magnetron, they replace the whole oven which is probably what you will end up doing.

There is a possibility that the circuit that provides power to the magnetron is faulty and you need to take it apart, find the proper electrical leads and test them with a volt meter. To do this you have to remove it from its mounting and take it apart. It is a fairly lengthy process however.
