GE Appliances Oven Error Code F3
Oven temperature sensor open circuit
The most common cause of the F3 error on a GE Appliances oven is sensor failure (open circuit) (~65% of cases); start with: test the sensor.
What Does Error Code F3 Mean on a GE Appliances Oven?
Oven temperature sensor open circuit.
F3 fires when the control board (ERC) reads infinite resistance on the RTD oven temperature sensor circuit, indicating an open condition rather than a value outside range. A healthy GE sensor measures roughly 1,080 ohms at room temperature; an open reading (OL/∞) means the board receives no usable feedback and disables heating for safety. This distinguishes it from F4, which typically flags a shorted or out-of-range sensor, and from F2, an over-temperature condition where the sensor is still reporting.
What Causes Error Code F3?
Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:
- 1 Sensor failure (open circuit) 65% of cases
- 2 Sensor connector loose or corroded 25% of cases
- 3 Wiring harness damaged 10% of cases
How to Fix GE Appliances Oven Error Code F3

Test the sensor
At room temp, GE oven sensor should read ~1,080 ohms. Open circuit (OL/∞) = sensor failed.
🔩 Multimeter - 2
Reseat connector
Check and firmly reseat the sensor connector at the sensor and at the control board.

Replace the sensor
Located in the upper-back of the oven cavity.
🔩 GE oven temperature sensor ($20–$55)⚠️ Allow oven to cool completely before reaching inside.
How to Reset Error Code F3
After replacing sensor, restore power and test with a 350°F bake cycle.
Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.
