Microwave runs but does not heat. One of the thermostats is measuring open (P22 KSD-40LC70). Thermostat is located on the base of the unit and has red wires attached to it. It is non conducting at room temperature. Is that correct? The other three thermostats in the unit are conducting at room temperature.

Verified all the door switches work. Verified 120VAC to the input of the high voltage transformer while the microwave is running, Check diode out of circuit and it is dropping 3.7 Volts, so I think that is okay. Suspect the magnetron at this point as the connectors are somewhat charred.

Please advise
