LG fridge-freezer error codes
LG fridge-freezers display an error code such as rS, FS, CF or FF when a sensor, fan or the defrost system fails. Find your code below for the meaning and safe checks.
| Code | Meaning | Severity | First action |
|---|---|---|---|
| rS | Refrigerator sensor error | Often fixable at home | The fridge compartment sensor is out of range, so the display cannot confirm fridge temperature. |
| FS | Freezer sensor error | Often fixable at home | The freezer sensor is out of range; cooling control in the freezer is unverified. |
| CF | Condenser fan error | Often fixable at home | The condenser (back-panel) fan is not running, so the appliance cannot reject heat properly. |
| FF | Freezer fan error | Often fixable at home | The fan inside the freezer compartment is jammed or failed, so cold air is not circulated. |
Safety first
Unplug before any check. Never open panels beyond the filter flap. Anything involving internal wiring, the heater or gas must go to a professional — see each code page for its "call a professional when" line.
