Fault codes, also called error codes or fault codes, allow your device to automatically report an internal malfunction. Below you will find the list of fault codes for your LG refrigerator and their meaning: this will give you an indication to best diagnose the origin of the malfunction of your appliance.
The error code can be read directly on the front panel of your LG refrigerator. Depending on the model, you can read this code on a display (for example, “Err 01”) or by observing the number of LED flashes (for example: 4 LED flashes = “Err 04”).
Refer to the user manual for your LG fridge to find out the exact meaning of the fault code displayed or the lights that flash. The number of flashes often corresponds to the error code number, but there are specificities linked to each model and brand.
ERROR CODE FS – FREEZER TEMPERATURE PROBE
This error code indicates a failure of the temperature probe located in the freezer.
Check the connections of this probe, its condition and replace it if necessary.
ERROR CODE RS OR RT – REFRIGERATOR TEMPERATURE PROBE
This error code indicates a failure of the temperature probe located in the refrigerator.
Check the connections of this probe, its condition and replace it if necessary.
ERROR CODE F DS – DEFROST SENSOR
This error code indicates a defrost sensor failure.
Check the connections of this probe/sensor, its condition and replace them if necessary.
IS ERROR CODE – ICE SENSOR
This error code indicates a failure of the ice sensor.
Check the connections of this probe/sensor, its condition and replace them if necessary.
ERROR CODE SS – PANTRY SENSOR
This error code indicates a fault in the pantry.
Check the connections of this probe/sensor, its condition and replace them if necessary.
ERROR CODE GF – FLOW METER
This error code indicates a problem with the flow meter.
Check the connections of this sensor, its condition and replace it if necessary.
ERROR CODE ER DH OR R DH – DEFROSTING
This error code indicates a problem when defrosting your refrigerator. The temperature probe does not send the correct values ​​to the electronic card.
Check the defrost sensor connections and its condition and replace it if necessary.
ERROR CODE CF / FF / IF / RF – FAN
This error code indicates a refrigerator fan failure. No signal is detected in return from the fan despite it being started.
Check the fan connections, that nothing is blocking its rotation and replace it if it is in poor condition or not working.
