Understanding the F3 Error Code

What the F3 Error Means

The F3 error code on a GE oven signifies an issue within the oven’s temperature sensor circuit. The temperature sensor, commonly called an RTD (Resistive Temperature Device), measures the oven’s internal temperature and relays this information to the oven’s control board. When the sensor fails or encounters issues within its wiring, the oven may receive incorrect temperature readings, subsequently displaying the F3 error code.

Common Causes of F3 Error Code

• Faulty Temperature Sensor: A malfunctioning temperature sensor is the predominant cause of an F3 error. The sensor may degrade with continued usage, resulting in inaccurate or inconsistent temperature readings.
• Wiring Issues: Another potential cause is damaged or loose wiring connecting the sensor to the control board. This prevents proper signal transmission and triggers the F3 error.
• Control Board Problems: Although rare, a malfunctioning control board may fail to interpret the sensor’s signals accurately, displaying the F3 error code.

Next Steps

The initial step in addressing the F3 error is to test the temperature sensor to confirm its operational status and accuracy. A multimeter can be used to check the sensor’s resistance and, from there, determine if replacement or wiring adjustments are necessary.

How to Fix F3 Error Code Ge Oven: Testing the Oven Temperature Sensor

Step 1: Locate the Temperature Sensor

The temperature sensor is usually situated in the upper rear corner of the oven’s interior. It is a critical component in monitoring and maintaining the oven’s temperature. To access the sensor, remove the oven racks, which gives you more room to maneuver. Depending on your oven model, you may also need to remove a cover panel inside the oven to fully expose the sensor.

Step 2: Remove the Sensor

Using a screwdriver, carefully unscrew the temperature sensor from its mounting location. This typically involves removing two screws that hold the sensor in place. Once these screws are removed, gently pull the sensor forward to expose its wiring harness. Take care not to tug on the wires as you disconnect the sensor from the wiring by gently pulling the connector apart; forceful handling can damage the wiring or connectors.

Step 3: Test the Sensor with a Multimeter

After the sensor is disconnected, it’s time to test it using a multimeter. Set your multimeter to the resistance (ohms) setting, usually indicated by the omega (Ω) symbol. Place the multimeter’s probes on the two terminals of the sensor. For a functioning sensor, you should see a reading of around 1100 ohms at room temperature (approximately 70°F or 21°C). If the reading is significantly outside this range, consider the sensor faulty and plan to replace it.

Step 4: Inspect the Sensor for Damage

Examine the sensor for any visible signs of damage, such as burn marks, cracks, or broken wires. If any damage is evident, even if the multimeter reading falls within the acceptable range, the sensor should be replaced. Damage like this can lead to intermittent issues and may eventually cause the sensor to fail completely.

Step 5: Reconnect the Sensor (If Functional)

If the temperature sensor passes both the resistance test and the visual inspection with no signs of damage, then it is likely still functional. In this case, reconnect the sensor to the wiring harness by aligning the connector and gently pushing it back into place. If the sensor fails either the resistance test or visual inspection, proceed to the next section for instructions on replacing the sensor.

Replacing the Oven Temperature Sensor

Step 1: Purchase the Correct Replacement

If you’ve determined that the temperature sensor is faulty, purchasing a replacement sensor compatible with your specific GE oven model is essential. To ensure you have the correct part, refer to your oven’s user manual or locate the model number, typically found on a sticker inside the door frame or on the back of the oven. Use this information to search for and confirm the correct part number, either through the manufacturer’s website or a reputable appliance parts supplier.

Step 2: Remove the Faulty Sensor

Carefully remove it from the oven with the sensor disconnected from the wiring harness and unscrewed from its mounting. Handle the sensor gently to avoid damaging the surrounding components or the wiring harness, which you will need to connect to the new sensor.

Step 3: Install the New Sensor

Begin installing the new sensor by aligning its connector with the wiring harness and pressing gently to secure the connection. Make sure it is firmly in place to avoid any loose connections. Next, position the sensor in its designated spot within the oven, aligning it with the mounting holes. Use a screwdriver to carefully fasten the screws, ensuring that the sensor is securely attached to the oven wall.

Step 4: Test the Oven

After successfully installing the new sensor, restore power by turning on the breaker or plugging the oven back in. To verify the repair, set the oven to a specific cooking temperature and observe its operation. If the F3 error no longer appears and the oven maintains the chosen temperature without issues, the sensor replacement has been successful. If the problem persists, further diagnosis may be required, potentially involving professional service.

Inspecting the Wiring and Control Board

Step 1: Inspect the Sensor Wiring

If replacing the temperature sensor does not resolve the F3 error, the next step is to check the wiring that connects the sensor to the control board. Start by visually inspecting the wiring for any apparent issues. Look for signs of frayed or burnt wires, loose connections, or corrosion at any junction points. Such damage can disrupt the accurate transmission of temperature readings and lead to persistent error codes.

Step 2: Test the Wiring Continuity

After completing the visual inspection, a multimeter will be used to test the wiring continuity between the sensor and the control board. This involves checking if the electrical current can flow through the wire without interruption. Set your multimeter to the continuity setting, which is typically depicted with a soundwave or diode symbol. Connect the probes of the multimeter to each end of the wire. A continuous beep or a display of zero resistance signifies intact wiring. If the multimeter does not beep or shows considerable resistance, this indicates a break or weak spot in the wiring, which will require repair or replacement.

Step 3: Check the Control Board

If both the sensor and wiring are confirmed to be in good condition, the cause of the F3 error may lie within the oven’s control board. This critical component is responsible for processing the signals received from the temperature sensor. Although control board failures are infrequent, they do occur and can lead to various operational issues, including erroneous temperature readings and error codes.

Step 4: Reset or Replace the Control Board

Before considering a control board replacement, try resetting the board by disconnecting the oven from the power supply for several minutes and then reconnecting it. This simple reset might resolve the error by clearing any temporary malfunctions. If the F3 error persists following the reset, a replacement of the control board could be necessary. Given the complexity of this replacement task, it is often recommended to seek professional assistance to ensure safe and effective installation.

Resetting the Oven

Step 1: Turn Off the Power

To begin resetting the oven, turn off the power by switching off the circuit breaker. Leave the power off for at least 5 minutes to allow the control board to reset properly.
