Oven Temperature Sensor Open Circuit
Quick Answer
Error code F3 on your GE Ovens & Ranges means: Oven Temperature Sensor Open Circuit. This is usually fixable — see the step-by-step guide below.
Affected Models
Likely Causes
  1. Oven temperature sensor (RTD) has failed with an open circuit
  2. Sensor wire has broken or a connector has come loose at the sensor or the control board
  3. Sensor probe tip is damaged from being bumped or knocked by oven racks
  4. Corrosion at the sensor connector inside the oven cavity
How to Fix It
1
Disconnect power and locate the oven temperature sensor (a probe inserted through the rear wall of the oven cavity)
2
Disconnect the sensor wires at the connector and measure resistance with a multimeter (should be approximately 1080 ohms at room temperature)
3
If the reading is infinite (open circuit), the sensor must be replaced
4
If the sensor reads correctly, check the wiring from the sensor connector to the control board for breaks
5
Replace the sensor by removing the two mounting screws inside the oven and pulling it out through the rear wall
Pro Tip
This is a common issue that most users can resolve without specialized tools. Try the first step before moving on to more complex solutions.
