Error code reference
LG fridge error codes explained
LG refrigerators display error codes to flag specific subsystem faults. Each code can have more than one root cause — our independent technicians interpret the code and confirm the underlying fault before repairing. Use the reference below, then book a diagnostic.
| Code | Meaning | Likely cause |
|---|---|---|
| ER CO / CO | Communication error between main board and display panel | Wiring fault, failed display board or main PCB |
| ER FF | Freezer fan error | Stalled freezer fan motor, obstruction or board output fault |
| ER 1F / IF | Ice maker / ice fan error | Ice fan motor failure or ice maker assembly fault |
| ER IS / IS | Ice sensor error | Failed ice sensor or sensor wiring |
| ER CH | Door / temperature sensor error | Door switch fault or compartment sensor failure |
| ER FS | Fridge (refrigerator) sensor error | Failed fridge compartment sensor |
| ER dH / dH | Defrost heater error | Open-circuit defrost heater or bimetal failure |
| ER rS / rS | Refrigerator sensor error | Failed refrigerator sensor or wiring |
| ER F3 / E3 | Freezer sensor error | Failed freezer sensor |
| 22 E | Freezer sensor / fan fault | Freezer sensor or fan motor failure |
| 33 E | Ice maker sensor fault | Ice maker sensor or assembly fault |
| 77 E | Ice maker motor / rotation fault | Ice maker motor or actuator failure |
| 88 88 | Display panel error / board reset | Control board reset state or panel fault |
Note: error codes are a starting point, not a diagnosis. We always test the subsystem the code points to before recommending parts.

ViewFrequently asked questions
What does ER CO mean on my LG fridge?
ER CO indicates a communication error between the main control board and the display panel. We test the connection and both boards to confirm whether a cable, the display board or the main PCB is at fault.
Why does my LG fridge error code come back after a power cycle?
A returning code means the underlying fault persists. We diagnose the subsystem the code points to rather than simply clearing it.
Can you clear an LG fridge error code?
We clear codes only after repairing the confirmed fault. Clearing a code without fixing the cause will not restore normal operation.
How do I read the error code on my LG fridge?
Most LG refrigerators show the code on the door or InstaView panel. Note the exact code before you call so we can prepare the correct diagnostic.
