Ge WB24X10025 Thermostat OEM Part

GE JKP90DP1BB over oven microwave would not power up after overcooking by a tenant. Removed control panel with 2 screws to access and check the main power ceramic fuse, thermal fuse, and top primary Interlock Switch, middle Monitor switch, bottom Secondary interlock relay. All done with difficulty without removing the microwave. No problem found. Removed microwave from above oven mounting and found addition thermal fuse cook senor on left near vented interior cavity open (fuse cooked), with partially melted plastic spade connector and wire on one side. The turntable motor was only partially working and gears stripped prior to this overcook incident so replaced that at the same time. I had the oven out which was easy. After the parts replacement unit powered up and appeared to cook, but turntable motor not working. Verified part good by ohming out and then directly connecting to 120V 60Hz duplex outlet with GFI. Trip the GFI before connecting the motor then reset to test. Power relay RY203 on the control board not supplying voltage. Also found out oven did not cook, but gave every indication it was working, other than the turntable. When the microwave oven is working properly 3 to 5 seconds after starting the Magnetron Tube can be heard with a distinctive hum. This was not the case, a slight click noise can be heard from the control board but the magnetron is not started. I believe I need to replace the control board mounted behind the touch screen panel to resolve.
