GE JGB735SPSS 5.0 cu ft Freestanding Gas Convection F4 Error Fix: Shorted Oven Temperature Sensor

Error code F4 on the GE JGB735SPSS 5.0 cu ft Freestanding Gas Convection means: Shorted Oven Temperature Sensor. The oven temperature sensor (RTD) circuit is shorted — the sensor wiring has been damaged causing a short circuit, or the sensor itself has failed with an internally shorted resistance element; test the sensor with a multimeter — resistance should be approximately 1,080 ohms at room temperature; if the reading is near zero ohms, the sensor or wiring is shorted; inspect the sensor wires inside the oven cavity for insulation damage where they may contact the oven liner or rack supports; replace the sensor and inspect the wiring
