GE Range Error Code F3 E0

The F3 E0 error code on a GE range indicates that the main oven temperature sensor circuit is open. In electric and gas ranges with electronic controls, the oven temperature sensor is a resistive thermistor that sends a continuously varying resistance signal to the control board. The board uses this signal to monitor oven temperature and regulate heating elements or gas valve operation. When the circuit reads an open condition, it means the resistance has gone effectively infinite, signaling that the electrical path through the sensor or its wiring has been broken entirely.

The most common causes of an open sensor circuit are a disconnected wiring harness, a broken sensor probe, or damaged wiring between the sensor and the control board. The sensor probe itself sits inside the oven cavity, typically mounted to the rear wall, and is subject to heat cycling, grease exposure, and physical contact that can degrade it over time. On some GE models, the sensor connector at the back of the range can work itself loose, which is why the first diagnostic step involves removing the back panel to confirm the sensor is properly seated.

Because the control board cannot confirm a safe oven temperature without a functioning sensor signal, the range will disable oven operation and display F3 E0 as a protective measure. Clearing the code requires resolving the underlying open circuit, whether that means reseating a loose connector, replacing damaged wiring, or installing a new temperature sensor. The sensor is typically the most straightforward replacement component in this circuit and is a common first repair when wiring continuity checks out.
