Lg Oven Error Code: F1F4

Error Code F1F4 alerts you to an issue with the oven thermistor. The thermistor is a temperature sensor that ensures the oven operates at the correct temperature. When it’s “open,” it means the thermistor is not providing the expected readings, which can affect cooking performance.

1. Immediate Action: If you see Error Code F1F4, stop using the oven to prevent any cooking issues. Turn it off using the control panel or by unplugging it.
2. Check Thermistor Connections: Inspect the thermistor’s connections to ensure they are secure. Loose or damaged wiring can lead to open-circuit conditions. Reconnect or repair as needed.
3. Test the Thermistor: You can use a multimeter to test the thermistor’s resistance. Consult your oven’s user manual for the specific resistance values that are expected for your model. If the readings are significantly outside the expected range, the thermistor may need replacement.
4. Reset the Oven: After addressing any connection issues and testing the thermistor, reset the oven. Turn it off and then back on to see if the error code reappears. Sometimes, this simple reset can resolve minor glitches.

A functioning oven thermistor is crucial for accurate temperature control and cooking performance. By following these steps and seeking professional help when required, you can address the issue and continue to use your LG oven effectively.
