Temperature in both ovens stays below set point. Preheat gets close to set temp then temp falls off 30 to 60 degrees below set point. Problem is with both ovens, but the upper oven temp diff is greater. I pulled the upper temp probe and it read 1087 ohms at room temp. any suggestions? Thanks.
You will want to access the control board and check the resistance of both of the oven sensors for the ovens. This reading will give you an idea of whether the wires for the oven sensors may be bad and causing loss of resistance. If the resistance checks ok at this point then you will want to replace the oven control board as it is not reading the resistances for the ovens properly.
