GE JB750SJSS Electric Convection Range F3 Error Fix: Open Oven Temperature Sensor (RTD)

Error code F3 on the GE JB750SJSS Electric Convection Range means: Open Oven Temperature Sensor (RTD). The oven temperature sensor circuit is open — the RTD (Resistance Temperature Detector) probe inside the oven cavity has broken internally, or the wiring between the sensor and the ERC is damaged or disconnected; the RTD probe is a thin metal rod typically mounted on the rear wall of the oven cavity; test the sensor with a multimeter — resistance should be approximately 1,080 ohms at room temperature (70°F/21°C) and should increase as temperature rises; if the reading is infinite (OL), the sensor is open and needs replacement; also check the wire harness connector at the ERC for corrosion or loose pins
