Need Schematic for GE combo Oven Microwave

I bought a used house and it came with this build in microwave/electric combo oven. The model number on the back of the microwave is 164D5312G016. However, the model number in the inside of the micowave is JTP86SF2SS. Someone took the actual schematic diagram out of the envelope that was attached to the steel shell that covers the microwave oven. I am trying to repair the oven and would like to get the schematic. The microwave doesn't heat. It has an unusual problem that when you open the microwave door, the light is on and the turn table turns. However, when you turn on the microwave, the light works inside, the blower works, but the turn table does not turn and no heat. I orginally thought that one of the three door switches were bad, but they seem to all check out. I suspect the power relay #2.
