It powers on. When try to make a cooking cycle and push start the clock counts down, the lights come on and you hear buzzing as if it was heating. But, you won't hear the fan running, turntable not spinning and the food will not be hot.
Checked the door interlock switches (top and bottom ones are normally open, middle one is normally closed) with a voltimeter for continuity and they all checked out good when the door is closed and when it is opened.
The original turntable motor (21V) was removed for inspection and discovered burn marks on it and had no continuity. Bought a replacement but still not working.
I couldn't locate the circuit schematics but I read that the magnetron cooling fan motor acts as secondary transformer to reduce the voltage going to the turntable moror.
Is there any common connection to not heating, fan not working and fried the turntable motor?
Please, advise.
Thank you
