What that error code means — and what you can safely check

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.

LG fridge-freezer error codes
CodeMeaningSeverityFirst action
rSRefrigerator sensor errorOften fixable at homeThe fridge compartment sensor is out of range, so the display cannot confirm fridge temperature.
FSFreezer sensor errorOften fixable at homeThe freezer sensor is out of range; cooling control in the freezer is unverified.
CFCondenser fan errorOften fixable at homeThe condenser (back-panel) fan is not running, so the appliance cannot reject heat properly.
FFFreezer fan errorOften fixable at homeThe 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.
