Dacor duel/fuel Rang ERSD36LP oven won't heat. stays on 135 degrees pre-bake on, never heats up, convection&broil doesn't work flipped the braker. Hit red reset buttons, still no heat. element is good

SOURCE: Dacro Wall oven (electric) does not heat past 345 degrees on bake or convection bake but broiler works and bottom oven works fine (for bake, convection bake and broil).

it could be the oven temp sensor rod located near the top of the inside of the oven,or possibly the bake element has a hot spot on the element and can no longer pass enough current thru this spot to correctly heat to your settings a hot spot on the element will look discolored in this area

like another person stated-from the front behind the door, take off the 6 screws and the cover by the latch. there is an "oven hi temp limit switch" It is crome with 2 heavy black wires connected to it. On the back side of this is a small red button which will reset the limit switch. I had the same issue (everything worked except the any of the heating elements) and quickly resolved.

SOURCE: heating element will not heat

With all that you said, I would suspect an open or faulty element. It is pretty much the most obvious solution.

If you have any electronically ability and you are going to open the oven, use an ohm or resistance meter, check the amount of ohms and use the upper element as a reference for the correct reading.
The element will either read open or good. You can use a light tester also and if the light lights between the two connectors of the elements, then it is ok and look elsewhere.

Heating elements are protected by a fusable link that is a one time fuse that is meant to protect the stove from overheating. It sounds like the elements need to be replaced

It worked for me but it was not like I was pushing the red button in. It seemed to be in the same place before and after I reset it.
