How to Fix Error Code F3

  1. Turn Off Power and Cool Down

    Always disconnect power before servicing electrical appliances to prevent shock. Never work on a hot oven as components can cause severe burns.
  2. Remove Oven Racks and Access Panel

  3. Locate the Temperature Sensor

  4. Test Sensor Resistance

    Ensure the sensor is at room temperature for accurate readings. A hot sensor will show higher resistance values.
  5. Check Wiring Harness

  6. Replace the Temperature Sensor

    Handle the new sensor carefully - avoid dropping or bending the probe as this can damage the internal element.
  7. Reassemble and Test

When to Call a Professional

Call a professional if the wiring harness is damaged and requires running new wires behind the oven cavity, if you're uncomfortable working with electrical connections, or if replacing the sensor doesn't resolve the F3 error code as this may indicate a faulty control board.

Frequently Asked Questions

What does F3 error code mean on a GE oven?
F3 error code indicates an open circuit in the oven temperature sensor, meaning the sensor has failed and cannot send temperature readings to the control board.
Can I still use my GE oven with F3 error?
No, you should not use the oven with F3 error as it cannot properly regulate temperature, which could result in undercooked food or potential safety hazards.
How much does a GE oven temperature sensor cost?
A replacement GE oven temperature sensor typically costs between $15-40 depending on your specific model, making it a relatively affordable repair.
How do I reset my GE oven after fixing F3 error?
After replacing the sensor and reassembling the oven, simply restore power. The error code should automatically clear when the control board detects the working sensor during the next heating cycle.
Why does my GE oven temperature sensor keep failing?
Frequent sensor failures can indicate electrical issues, excessive moisture in the oven cavity, or a faulty control board sending incorrect voltage to the sensor.
