Are you experiencing a puzzling F2 error code on your GE oven? Then you’re in the right place. In this guide, we’ll discuss everything you need to know about the GE oven F2 error code and provide step-by-step instructions to diagnose and resolve the issue. Whether it’s a simple glitch, ventilation problems, or more complex sensor and control board issues, we’ll walk you through the troubleshooting process, ensuring your oven is back to working correctly in no time.

All popular GE ovens are covered by this guide, including the following model numbers:






















What Does a GE Oven F2 Error Code Mean?

If you encounter an F2 (or F20) error code on your GE oven, the oven has detected that the temperature inside it has exceeded a predetermined limit. For most GE ovens, your oven’s highest temperature before setting off the error code is 615 degrees Fahrenheit during normal operation or 915 degrees Fahrenheit if you have a self-cleaning function.

Step 1 – Reset Your GE Oven

Sometimes, error codes can result from a temporary glitch in the main control board. If the error code appears unexpectedly or you haven’t used the self-cleaning function, try resetting the oven by disconnecting its power for a few minutes. Reconnecting the power can often clear the error code if it is due to a glitch. If the F2 error code still shows after you turn the oven back on, it may indicate a more serious issue that requires attention, so you must proceed to step 2.

Step 2 – Check the Oven’s Ventilation

Over time, oven vents or screens, especially in self-cleaning ovens, can become obstructed with grease or debris. Blockages can cause the oven to overheat and trigger the F2 error code. To ensure the efficiency of your oven’s ventilation system, check for obstructions in the oven’s fans. If you find any obstructions, remove them by cleaning the area around the fan. If there are no obvious obstructions or cleaning the fan area doesn’t remove the error code, you must proceed to step 3.

Step 3 – Inspect the Oven for Other Damage

Before inspecting the temperature sensor, relay, or control board, examine the oven for any damage caused by the heat of a self-cleaning cycle. If you identify damage to the oven’s interior, the self-cleaning feature is likely responsible for the F2 error code. This means you will need to get any damage repaired by a technician. If you don’t find any obvious damage in your oven, internal components must be tested (see the next steps in this guide).

Step 4 – Test the Temperature Sensor

The oven’s temperature sensor monitors the temperature and signals the control board to adjust the heat accordingly. The sensor is typically a metal rod with a sensor located inside the oven, usually near the back wall. You’ll need to measure its resistance with a multimeter to test it. The owner’s manual should provide the specific resistance values for your sensor at room temperature. Typically, GE models have a resistance of 1,080 to 1,090 ohms. If the resistance falls within this range, the sensor functions correctly, and you can proceed to the next step. If it’s above 1,090 ohms, the sensor is likely faulty and should be replaced.

Here’s how to replace the temperature sensor:

  • The first thing you need to do is purchase the correct replacement part. All major hardware retailers should stock replacement temperature sensors.
  • Once you have the correct replacement part, start by switching the circuit breakers responsible for powering the oven off.
  • Remove the oven racks so you can access the back of the oven.
  • Locate the temperature sensor (it’s at the back of the oven).
  • Remove the mounting screws that hold it in position.
  • Gently pull the sensor out and disconnect the wire harnesses. Use a pair of pliers if need be to dislodge the locking tab.
  • Connect the new temperature sensor to the wire harnesses.
  • Place the temperature sensor into position.
  • Secure it in place with the screws you removed earlier.
  • Once securely in place, turn your oven on and check if the F2 error code has stopped showing. If it is still showing, proceed to the final step.

Step 5 – Test the Control Board

If the temperature sensor is working correctly, the next common cause of the F2 error code is damage to the control board. Damage to the control board is often a result of the oven reaching extremely high temperatures, causing soldered connections to fuse together on the board. You can access the control board by removing the control panel, allowing you to inspect it for any noticeable damage. If you see damage, it will need to be replaced. However, control boards can be costly to replace and challenging to test, so professional diagnosis should be considered first.
