My top oven bake element is not heating, which is causing the top oven to heat incorrectly/unevenly. The temp sensor rises too fast, compared with an oven thermometer on the rack. This leaves the oven much too cold for baking.
I checked, and there is no voltage going to that element when the top oven is set to bake. The other three elements are working fine. I've traced the power back to the control PCB to what appears to be a relay. I can hear two relays 'engage', one presumably for each element, but still no power.
Could this be a thermostat issue? Might the controller think the oven is hot, even tho the temp readout shows the oven just warming up?
Everything points to a bad relay or controller, but since that's an expensive part I wanted to ask for suggestions about what I may have missed.
Sounds like you have it figured, need to spend some moola..........
You can ohm out the sensor to the oven should be about 1100 ohms at room temperature.((the sensor is the little rod with two wires attached to it sticking in the oven, as temps change resistance changes which is read by the board) The upper and lower oven sensors are probably the same,you could just swap them to test, but probably not necessary,might also be confusing if you do not do a lot of testing on a regular basis. Remember to unplug unit for safety.
The bake element if it was not bad should be about 20 ohms, bad would read open........
