Hi my name isXXXXX have been an appliance servicer since 1992.You either have a bad upper oven sensor or main control issue. Do you have an ohm meter so we may walk through some ohm test?
No, I do not have an ohm meter
Sorry for the delay getting back to you, but the volt/ohm meter would be the only way to determine the correct solution to the wall oven. If you want to part change i would change the main board and the sensor.This would solve your issue either way. Thermal sensor kit # XXXXXBoard kit# XXXXXDo a Google search for best pricing.The board can be replaced by removing the wall oven out and removing the top. And the sensor can be replaced by finding the probe in the upper oven and pulling out forward after removing screws.Hope this helps youAll I ask of you is to please rate me with one of the top 3 ratings.
