GE Range Error Code F3 E1

The F3 E1 error code on a GE range indicates that the main oven temperature sensor circuit has detected a short condition. In dual-oven models, this code specifically refers to the top oven sensor. The temperature sensor, also called an RTD (resistance temperature detector), is a probe mounted inside the oven cavity that continuously reports cavity temperature to the control board. Under normal operating conditions, this sensor varies its resistance across a predictable range as temperature changes. A shorted sensor means the resistance has dropped abnormally low, causing the control board to receive an inaccurate temperature signal and shut down oven operation as a safety precaution.

The most common causes of this fault are physical damage to the sensor probe or its wiring harness. When the sensor's internal resistance drops to near zero or falls well outside the expected range, the control board interprets this as a short circuit. This can result from a pinched or melted wire harness inside the oven cavity, a failed sensor probe, or a loose or corroded connector at either the sensor or the control board. The first diagnostic step is to unplug the range, remove the back panels, and confirm that the temperature sensor connector is fully seated and undamaged.

If the connector appears intact, the sensor itself should be tested with a multimeter for resistance continuity. A sensor reading near zero ohms or showing a dead short confirms the probe has failed and needs replacement. Wiring between the sensor and the control board should also be inspected for any signs of heat damage, pinching, or insulation breakdown. If the sensor and wiring both test correctly, the control board may be misreading the circuit and could itself be the cause of the fault.
