The unit is approx 7 years old. The other day it stopped heating. It runs but does not make the same 'pitch' when turned on. It also makes a smell like electronic burning. Time for a new unit?

Re:
This is going to be either the high-voltage transformer, the magnetron, or the high-voltage diode.
Magnetrons are the mosty common failure in these, and there is a campaign underway to replace "underperforming" magnetrons.

If the microwave oven is 7 years old or less, the cause is a bad magnetron, or the inverter board is malfunctioning, due to cost in parts and labour cheaper to replace.
If the microwave oven is 10 years old then it is time to consider a new unit, by your description it is going into cascade failure where different parts have stopped working, the buzzing sound is the magnetron warning you, it is about to fail. The fans job is to keep the magnetron cool while it is running.
The symptom that you have described sounds like the magnatron has failed, the microwave oven looks to be approx. over 9 years old, at that age and with a failed magnatron it is not cost effective to replace the part, it would be best to replace the microwave oven at this point. Good luck!
It could be a number of things, Burnt connections between the magnetron, Capacitor, Diode and transformer, Heater connections loose or burnt, Transformer, Capacitor Diode or Magnetron US. You need to strip it and find out if you are getting about 2000volts to the Mag, Are you getting approx 5volts across the heater terminals?? NOTE that the 2000 Volts can remain in the cap indefinitely and the voltage isLETHAL. IT WILL KILL YOU if you don`t take precautions. Ian
If the turntable does rotate, I'd suspect a more significant failure, such as the transformer, capacitor, or magnetron. If it's any of these, it's time to replace the unit.
