My Daewoo KOR-2000 Microwave doesn't heat anymore , can i fix it?

My microwave has stopped heating, all other functions work on it, fan, bulb, timer display etc. I have taken the cover off and checked the fuse inside, that is Ok. The switches for the door seem ok as well. Any help would be appreciated before i scrap it.

Quite often this is due to a bad door switch located inside behind the area where the door hooks go into the oven.

Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure.

No. Not unless you have been trained to do so - in which case you wouldn't be asking the question. There are numerous possible reasons for an oven "going through the motions" but not heating the food. It is extremely dangerous for an untrained person to try to repair a microwave oven, because it can possibly deliver a lethal electric shock, even after it has been disconnected from the mains.
In your case, there's no danger from microwaves. As it is not heating the food, there are none, but there may still be 4,000 volts at high current.
