Lg Oven Error Code: CF5/CF6/CF7

These error codes signify a problem with the IGBT sensor, which plays a critical role in regulating and monitoring various aspects of your oven’s operation. An open or short circuit in this sensor can disrupt its functionality, affecting the oven’s performance.

1. Immediate Action: If you encounter Error Codes CF5, CF6, or CF7, it’s essential to stop using the oven to prevent further complications. Turn off the oven using the control panel or by unplugging it.
2. Check Sensor Connections: Carefully inspect the connections of the IGBT sensor in your oven. Ensure that the sensor is correctly connected to its socket. Examine the wiring for any visible signs of damage, such as frayed wires or loose connections. If you identify any issues, address them.
3. Test the Sensor: To verify the condition of the IGBT sensor, you can perform a resistance test using a multimeter. The specific resistance values may vary depending on your oven model, so refer to the user manual for the correct resistance range. If the sensor readings are outside the specified range, it may need to be replaced.
4. Reset and Reattempt: After inspecting and potentially addressing sensor issues, you can attempt to reset the oven. Turn it off and then back on to see if the error codes reappear. If they don’t, you can test the oven’s performance by using it for cooking.
5. Professional Assistance: If Error Codes CF5, CF6, or CF7 persist, or if you are uncertain about the sensor’s condition or replacement, it’s advisable to contact a professional technician. They can perform a comprehensive diagnostic check, identify the specific issue with the IGBT sensor, and recommend and conduct any necessary repairs or replacements.

A properly functioning IGBT sensor is crucial for the accurate operation of your oven. By following these steps and seeking professional help when required, you can address the issue and continue to use your LG oven effectively.
