Unit not heating up. Having opened up the cabinet and turning the oven on you could smell the TRANSFORMER overheating.
Replaced the transformer, magnetron, diode, and checked out all the other thermostats and fuse. Tested the capicator and the meter showed
!.07 microfarads(it's value on the label). turned the unit on, and everything was working, but in a few seconds there seemed to be a draw-down of power, the lights stayed on but dimmed, the water in the test cup got hot but it took longer to heat than normal.
Is this a bad capacitor or possibly something else?

Maybe a bad control board or bad stirrer motor?

was the antenna burned or melted on the old magntron ?
If so look inside the the magntrons mounting hole , is the metal it faces melted or distorted , if it's a painted metal , is the paint burned ? (this cannot be fixed so don't even try)
if the metal has ANY damage of any kind , the microwave will never work right and will overheat the magntron
I am also just guessing but you did check the simple stuff , like the cooling fan

What's the current draw on the magnetron? Should see around 11 to 12 A.
