This is most likely a defective magnetron, especially with the burning smell. There are two other parts that can be a problem, the high voltage capacitor and diode, all three work together to heat food. If the magnetron is the culprit, probably cheaper to replace the microwave oven.

You may have a failure of the H.V. rectifier. I would recommend that a trained technician replace this part due to the high voltage potential.

Sounds like the problem is in the high voltage. Most common would be magnatron, capacitor and diode. For safety reasons this should be checked by a professional. Look in your owners manual because some high voltage parts have a longer warranty than 1 yr.
