Hi, im looking for any help i cant get i have a ge profile i believe its a JTP85WW2WW but the sticker on the oven door is faded off. It will not heat in the bake, convection, roast, or boil modes the display reads 100 degrees, but never even trys to heat. I have tested continuity of all the heating elements and they apear to be fine. Not sure where to go from here. Thanks in advance.

All those elements operate on 240 volts, the rest of the appliance on 120V. A first step would usually be to confirm the full 240 volts is getting to the appliance.

The following link shows how to test for proper voltage at a range wall outlet.

LINK > The Appliance Clinic : Electric Range : All Elements Fail to Heat


Further tests would be needed where the range cord (or house wiring) attaches to the stove's internal wiring if the outlet voltages test Ok.

PS. The wiring diagram you posted only pertains to the microwave section. If the problem is with the conventional oven, a photo of its wiring diagram may be needed to locate other potential failure points.
