GE Ovens & Ranges F2 Error Code (Over Temperature): How to Fix It Yourself

The F2 code on a GE oven means the control board detected a temperature higher than normal. This usually happens because the oven temperature sensor has drifted or failed, telling the board the temperature is dangerously high when it may not actually be. The sensor is an inexpensive and easy part to replace.

⚡ Difficulty: Medium⏱ 20-45 minutes💰 Parts cost: $15–$50🔧 Tools: Phillips screwdriver, Multimeter, Nut driver (1/4 inch)

⚠️ Safety First

  • Turn off the oven and let it cool completely before working on it.
  • Turn off the oven's circuit breaker — ovens use 240V which is especially dangerous.
  • Do not attempt this repair if your oven uses gas — the F2 code in gas ovens may involve gas valve issues.

Step-by-Step Repair

  1. 1

    Turn off power and let the oven cool

    Cancel any running cycle and turn off the circuit breaker for the oven. If the oven was running and is actually very hot, let it cool for at least an hour before working inside. Safety first — ovens run on 240V which is dangerous.

  2. 2

    Locate the temperature sensor

    Open the oven door and look at the top of the back wall inside the oven. You will see a thin metal rod or probe sticking out a few inches — that is the temperature sensor (also called an RTD probe). It is usually held in place by one or two screws.

  3. 3

    Test the sensor with a multimeter

    Disconnect the wire plug from the sensor (you may need to pull the oven out slightly to reach it from the back). Set your multimeter to ohms. At room temperature, a working GE oven sensor should read approximately 1,080-1,100 ohms. If you get a very high reading, zero, or no reading at all, the sensor is bad.

  4. 4

    Replace the sensor

    Remove the one or two screws holding the sensor bracket inside the oven. Pull the sensor out through the back wall. Feed the new sensor through the hole, screw it in, and reconnect the wire plug. Make sure the connection is snug.

  5. 5

    Restore power and test

    Turn the circuit breaker back on. Set the oven to 350 degrees and let it preheat. Use a separate oven thermometer to verify it reaches the right temperature without the F2 code appearing. If the code comes back with a new sensor, the control board may be at fault.

If That Didn't Work

  • Faulty oven control board
  • Shorted wiring between the sensor and the control board
  • Runaway relay on the control board keeping the element on

When to Call a Professional

If the new sensor does not fix the F2 code, the control board may have a stuck relay that keeps the heating element on. Board replacement runs $150–$350 with labor. Since ovens use 240V, this is a good time to call a professional if you are not confident.
