The top oven when you set temp to 350 F comes on but top heating element is on broil and today it is not wanting to even preheat. We keep taking panel off and and resetting the heat sensor but now it is every time. Do we need to replace only the heat sensor?
You have to keep opening the control panel and resetting the thermal switch 62775 then most likely the thermal is faulty and would need to be replaced. If after replacing it, the thermal switch trips again then you will want to look for an over heating issue in which you will want to test the oven sensor 72752 which should have a resistance of 1090 ohms.
MY DUAL FUEL RANGE IS GIVING ME AN F4 ERROR SIGNAL WHEN I TRY TO TURN THE ELECTRIC OVEN ON.WHAT DO I HAVE TO DO TO GET THINGS WORKING
The F4 erro is an open oven temperature sensor. You will want to check the oven sensor harness and harness connection between oven sensor and oven control. Replace the sensor if the wiring is ok.
