F1 Defective touch pad or clock (ERC) Replace touch pad or clock (ERC). Touch pad is a more common problem. Refer to F1 test at the top of this page for more information. F3 or F4 Shorted or open oven temperature sensor (RTD) Check sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

Hi hardcaseone,

The F3 fault code description is a shorted or open oven temperature sensor (RTD). Please check the sensor harness and harness connection between oven sensor and oven control. Replace oven temperature sensor (RTD) if wiring is ok.

Hope it helps.

Thank you for using FixYa.

There is only one sensor. Look inside the oven on the top right or left rear. The sensor is about 3 inches long,metal and about the size of a thin pencil. It will be held in by one or 2 screws. Unplug the range. Remove the sensor and disconnect the wires. Use a volt meter set for ohms. It should read 1100 ohms plus or minus 50 ohms. If it reads more or less replace it.
If you have no meter just replace the sensor. It is bad if the control says it is bad.
