What Does F31 Mean on a Stove and How to Troubleshoot It

What Does F31 Mean on a Stove?

The F31 code on a stove usually indicates a faulty thermometer sensor probe, wiring harness, or control board.

To troubleshoot this issue, start by shutting off the electricity or gas supply to the oven.

Then, examine the sensor probe’s cable, tighten any loose connections, and test the oven.

If the code persists or the connection was already tight, unplug the wire harness from the control board and use a multimeter to check for resistance and shorts.

Depending on the readings, you may need to replace the probe or the control board.

Finally, restore power to the oven and run a test to ensure the issue is resolved.

Key Points:

  • F31 code on a stove indicates a faulty thermometer sensor probe, wiring harness, or control board
  • Troubleshoot by shutting off electricity or gas supply to the oven
  • Examine sensor probe’s cable, tighten loose connections, and test oven
  • If code persists, unplug wire harness from control board and check for resistance and shorts with a multimeter
  • Depending on readings, replace probe or control board
  • Restore power to oven and run a test to ensure issue is resolved

Did You Know?

1. The F31 code on a stove is an indicator of a faulty oven temperature sensor. This sensor measures the temperature inside the oven and sends a signal to the control board, helping to maintain a consistent cooking temperature.

2. F31 is just one of many error codes that stoves can display, providing a specific troubleshooting indicator for technicians and consumers. These error codes can help identify and resolve issues without the need for extensive diagnostics.

3. In some stove models, an F31 error code can also signify a problem with the oven’s control board. This component is responsible for regulating the oven’s functions, such as heating elements and timers.

4. The F31 error code is more commonly seen in electric stoves rather than gas stoves, as electric stoves rely on sensors to monitor and regulate temperature more than gas stoves do.

5. The F31 code often requires a professional technician to diagnose and repair the issue accurately. Attempting to fix it yourself without the necessary knowledge or tools can potentially lead to further damage or safety hazards.

1. Understanding The F31 Error Code On A Stove

When troubleshooting stove issues, one common error code that may appear is F31. This code typically indicates a problem with the thermometer sensor probe, wiring harness, or control board. The F31 error is less common and is usually found in older stove models. It is important to address this issue promptly to ensure the proper functioning of your oven.

Improvements:

  • Emphasized the error code F31 using bold.
  • Highlighted the potential causes of the error: thermometer sensor probe, wiring harness, and control board.
  • Clarified that the F31 error is less common and typically occurs in older stove models.
  • Emphasized the importance of addressing this issue promptly to ensure the proper functioning of the oven.

2. Troubleshooting Steps For F31 Error On Electric Ovens

If you have an electric oven and encounter the F31 error code, it is crucial to shut off the electricity supply before proceeding with any troubleshooting steps. Safety should always be the top priority. Once you have turned off the power, carefully pull the oven away from the wall to gain access to the back.

Next, take a close look at the sensor probe’s cable, which is typically coated in purple. If the cable is loose, tighten the connection and perform a test run to see if the F31 code disappears. If the connection was already tight or the code still appears, it is time to move on to the next step.

Unplug the wire harness from the control board and use a multimeter to check for resistance on the purple wires’ terminals. A reading of around 1080 ohms is considered normal. However, if the reading is lower than that, it indicates a defective probe that needs replacement. To further diagnose the issue, place one probe on the purple wire’s terminal and the other on bare metal inside the oven to check for shorts. If the wires show a 0-ohm reading, there is a short, and if the multimeter shows an OL reading, it indicates a defective control board.

To prepare for the replacement of the control board, take a picture of the wiring configuration for reference. Remove the old control board and install the new one, ensuring that the mounting holes align properly. Secure the new board with mounting screws. Once this step is complete, restore power to the oven and perform a test run to verify if the F31 error has been resolved.

3. Troubleshooting Steps For F31 Error On Gas Ovens

For gas ovens, troubleshooting the F31 error follows a similar process as electric ovens, but with additional safety precautions. It is crucial to shut off the gas supply or disconnect the gas line before attempting any troubleshooting steps to ensure safety. Once the gas is turned off, pull the oven away from the wall for easy access to the back.

Follow the same steps as mentioned earlier for electric ovens:

  • Examine the sensor probe’s cable and tighten any loose connections.
  • Conduct a test run to check if the F31 code persists or if the connection was already tight.
  • If the issue persists or the connection was already secure, proceed to unplug the wire harness from the control board.

Using a multimeter:

  • Check the resistance on the purple wires’ terminals. A reading of around 1080 ohms is normal, while a lower reading indicates a faulty probe.
  • Additionally, perform the short test by placing one probe on the purple wire’s terminal and the other on bare metal inside the oven. A 0-ohm reading suggests a short, while an OL reading implies a defective control board.

For reference, take a picture of the control board’s wiring before proceeding. Then, replace the old control board with a new one, ensuring the alignment of mounting holes and using appropriate mounting screws.

Finally, restore the gas supply and perform a test run to verify if the F31 error has been resolved.

4. Checking The Sensor Probe And Wiring For F31 Error

When troubleshooting the F31 error code, carefully examine the sensor probe and its wiring. The sensor probe is responsible for detecting the oven’s temperature, and any issues with it can trigger the F31 error. The cable attached to the probe is often coated in purple for easy identification.

Here are the steps to follow:

  • Check if the cable is loose. If it is, tighten the connection and perform a test run to see if the F31 error disappears.

  • If the connection was already tight or the error persists, check the resistance on the purple wire’s terminals using a multimeter. A reading of approximately 1080 ohms is considered normal. If the reading is lower than that, it indicates a defective probe that needs replacement.

  • To further investigate, perform a short test on the wires. Place one probe on the purple wire’s terminal and the other on bare metal inside the oven. If the multimeter shows a 0-ohm reading, there is a short in the wiring. On the other hand, if the multimeter displays an OL reading, it suggests a defective control board.

  • If you suspect a defective control board, it is recommended to contact a professional for further assistance.

Please note that proper safety precautions should be followed when working with electrical components.

5. Replacing The Control Board For F31 Error Resolution

If the previous troubleshooting steps haven’t resolved the F31 error, it may be necessary to replace the control board. Before starting this process, take a picture of the control board’s wiring for reference later on.

To replace the control board, follow these steps:

  • Remove the old control board by disconnecting the wire harness and other necessary connections.
  • Once the old control board is out, install the new control board, ensuring that the mounting holes align properly.
  • Secure the new board in place using the appropriate mounting screws.
