Lg Refrigerator Error Code: Er FS

The “Er FS” error code on an LG refrigerator typically indicates a problem with the freezer sensor. This error may be triggered by issues related to the sensor’s function or its wiring. To troubleshoot this error:

1. Check Sensor Wiring: Inspect the wiring connections of the freezer sensor. Ensure that they are secure and not damaged. Loose or damaged wires can cause false readings and trigger the error code.
2. Test the Freezer Sensor: Use a multimeter to test the resistance of the freezer sensor. Refer to your refrigerator’s manual for the correct resistance values. If the sensor’s resistance is out of the specified range, it may need replacement.
3. Defrost the Freezer: In some cases, ice or frost buildup in the freezer can affect the sensor’s accuracy. Thaw the freezer, remove any ice buildup, and then monitor the refrigerator for the error code.

If the “Er FS” error persists after performing these DIY checks and solutions, it’s recommended to contact a professional technician or LG customer support for further diagnosis and repair. They can provide more specific guidance and ensure that your refrigerator is functioning correctly.
