Oven will not heat fully to set temperature. If i set it at 400, it might make it to 325. I replaced the bake element and temperature sensor and did not resolve the issue. What else is left?
The broil element heats good? Just not the bake element? Have you checked for 240 volts across the bake element terminals? Meaning touch each meter probe to each bake element terminal and see if you get 240 volts when its set on bake 400 F.
The only other part that controls the bake element, per your wiring diagram, is the oven control board:
