If it looks and sounds like it's running but doesn't heat, one possibility is that the magnetron tube has burned out. This is the electronic tube that emits the microwave radiation. Another possibility is that the control circuit that regulates turning the magnetron tube on and off for defrosting and lower-than-100-percent heating rates could be faulty. Try heating with the defrost setting and at full power and see if either method results in any heating. The cost of replacing the magnetron at a repair shop could be high enough that you might rather just buy a new microwave oven. My father replaced the magnetron tube himself, but he's an electronic engineer. I wouldn't recommend that just anyone try it. How new/old is it?
It sounds like one of the door switches has become defective, each must be disconnected on the one side and tested with a digital meter using the ohms scale.
The problem is the magnetron. This is the part of the microwave that heats the food. partselect,com likely has your part with a diagram and great prices.
When the microwave does not heat the food, it means that the magnetron circuit has failed. It the part that generates the microwaves that heat the food. Often the part fails by shorting out causing a loud buzzing sound when you try to microwave something. The replacement part usually costs almost as much as a new oven, so it rarely cost effective to replace. Sorry.
Probably a 'desd' magnetron or its associated fuse. Take it to a repairer - do not open the case yourself as they are potentially dangerous even months after being unplugged from the power.
It may be a shorted diode in the HV power supply for the magnetron. Open the case to get to the part. Unplug the machine before opening anything. This is normally a high voltage area when running.
HI, the high voltage capacitor is unstable and, it has damaged the Magnetron. you will need to replace the Magnetron. it will run you about $191.30. this will restore the heating action in your microwave unit.
