What You'll Learn
The F2 error code means the oven's temperature has exceeded a preset threshold
If your General Electric (GE) oven displays the F2 error code, it means that the oven's temperature has exceeded a preset threshold. In simple terms, the oven's temperature has surpassed 615–630 °F or 915–930 °F during a self-cleaning cycle. This temperature range is considered potentially dangerous and damaging to the oven. When this happens, the oven will shut down automatically until the issue is addressed.
The F2 error code specifically indicates a problem with the oven's temperature regulation system. It could be due to a malfunctioning temperature sensor or a faulty thermostat, disrupting the harmony needed for accurate temperature control. The temperature sensor and thermostat work together to match the internal temperature with the desired setting. The temperature sensor gauges the actual temperature inside the oven and communicates this information to the thermostat. The thermostat then adjusts the heat output to maintain the desired temperature.
To resolve the F2 error code, you should first test the temperature sensor. Disconnect the wiring harness that goes to the temperature sensor by depressing the wiring harness tabs with a flat-head screwdriver. Remove the temperature sensor from the oven and perform a continuity test using a multimeter or ohmmeter. Consult your oven's manual to determine the expected resistance range for an accurate test. If the sensor is faulty, replace it with a new one.
If the temperature sensor is functioning correctly, the next probable cause of the F2 error is a defective control board. The control board may have been damaged due to the oven reaching extremely high temperatures, causing the soldered connections to fuse together. Access the control board by removing the control panel and inspect it for any visible damage. If the control board is faulty, it will need to be replaced.
In some cases, the F2 error code may be triggered by factors unrelated to the temperature sensor or control board. For instance, blockages in the oven vents or screens, especially in self-cleaning ovens, can cause the oven to overheat and trigger the error code. Therefore, it is important to regularly clean the oven and ensure that the ventilation system is free of obstructions.

The oven's temperature sensor may be malfunctioning
If your General Electric oven is displaying the F2 error code, it means that the oven is detecting that the temperature inside has exceeded a preset threshold. In other words, the temperature has exceeded 615°C or 915°F during a self-cleaning cycle. This is a warning that the oven's temperature is reaching potentially dangerous and damaging levels, and the oven will shut down until the issue is resolved.
If the oven struggles to reach the set temperature or takes too long to preheat, the temperature sensor might be faulty. A malfunctioning sensor can cause the oven to overheat, resulting in burnt food. It can also cause temperature spikes, where the temperature goes up and down erratically. These spikes can occur in 10 to 20-degree increments and may not return to the correct temperature.
If you suspect that your oven's temperature sensor is faulty, it's important to have it checked and replaced by a professional.

The oven's control board may be damaged
The F2 error code on a General Electric oven indicates that the oven's temperature has exceeded 615°C or 915°F. This could be due to a faulty temperature sensor or a defective control board. If the oven's control board is damaged, it may need to be replaced.
Before attempting any repairs, ensure the oven is unplugged for safety. The control board can be accessed by shutting off the house circuit breaker(s) and disconnecting the oven from the power supply. Then, pull the oven slightly out of its cabinet and open or remove the top panel. The control board is located behind the control panel display.
To determine if the control board is faulty, test the power between terminals P1-1 (black wire) and P1-3 (white wire). If there is no reading of 110 volts, the control board is damaged and needs to be replaced. It is also possible to test the control board by checking for 5 volts DC going to the temperature sensor. If the sensor is functioning correctly, the control board is likely faulty and will need to be replaced.
In some cases, the problem may be caused by a blown fuse in the control panel. This can be checked using a multimeter to test for continuity through the thermal fuse in the power supply wire going to the control board. If the multimeter measures infinite resistance, the fuse is blown and must be replaced.
If you are uncomfortable performing these maintenance tasks yourself, it is recommended to contact a professional technician for assistance.

The oven's vents or screens may be blocked
If you see an F2 error code on your General Electric oven, it means that the oven's temperature has exceeded a preset threshold. In simple terms, the temperature has exceeded 615°C or 915°C Fahrenheit during a self-cleaning cycle. When this happens, the oven will shut down until the issue is resolved.
One of the reasons for the F2 error code could be that the oven vents or screens are blocked. Oven air vents are strategically located openings designed to facilitate the flow of air in and out of the oven cavity. These vents play a crucial role in maintaining proper airflow within the oven, ensuring even heat distribution, and preventing the accumulation of harmful gases.
Over time, oven vents or screens can become clogged with grease, food spills and splatters, food debris and particles, and environmental factors such as dust, pet hair, and airborne pollutants. This buildup can obstruct airflow, disrupt cooking performance, and even pose safety hazards. For example, restricted airflow can lead to uneven heat distribution, resulting in inconsistent culinary results. It can also increase energy consumption and operating costs, as the oven has to work harder to maintain the desired temperature.
If you suspect that your oven's vents or screens are blocked, it is important to clear the blockage and restore proper airflow. This may involve thorough cleaning and maintenance to remove accumulated debris. You can try cleaning the oven with vinegar or baking soda to resolve the error code. If the issue persists, you may need to consult a trained technician to troubleshoot the problem.

The oven's relay may be damaged
If your General Electric oven is displaying an F2 error code, it means that the temperature inside the oven has exceeded a preset threshold. In simple terms, the temperature has exceeded 615°C or 915°C Fahrenheit during a self-cleaning cycle. When this happens, the oven will shut down until the issue is resolved.
If the F2 error code was triggered during the self-cleaning function, the self-cleaning cycle may have damaged the interior of the oven or a component, like the control board. If the self-cleaning function did not damage the oven, the oven's temperature sensor or the control board may be defective. Glitches and clogged ventilation can also cause the error code.
If the oven's relay looks damaged, you will need to replace the oven's electronic control board. However, if the relay looks to be in good condition, you can move on to checking the oven's temperature sensor. If there are any exposed or damaged wires, the temperature sensor is misreading the oven's heat, causing the F2 error code. If you find any damaged or exposed wires, you will need to replace the entire component.
