Lg Refrigerator Error Codes

All Lg refrigerator error codes with step-by-step troubleshooting, multimeter specs, and OEM part numbers.

21 error codes

Code	Meaning	Severity	Difficulty
1F	The freezer defrost temperature sensor has failed or is reading out of its expected range, preventing the automatic defrost cycle from operating correctly. highintermediate	high	intermediate
CF E	The condenser fan motor has stopped running. This fan blows air across the condenser coils to dissipate heat from the compressor. Without it, the compressor overheats and the refrigerator stops cooling. highintermediate	high	intermediate
CH E	CH E on an LG refrigerator indicates a chamber (compartment) temperature sensor has failed or is reading outside its expected range. LG refrigerators have multiple temperature sensors for different zones. mediumintermediate	medium	intermediate
CL E	CL E on an LG refrigerator indicates a communication or cooling fan fault in the door section. This code appears on LG French door and side-by-side models with the Linear Compressor system. mediumintermediate	medium	intermediate
COMPRESSOR	Linear Compressor Warranty and Diagnosis mediumintermediate	medium	intermediate
DH F	The defrost heater assembly has an open circuit or the thermal fuse in the defrost circuit has blown. The automatic defrost cycle cannot run, and frost will accumulate on the evaporator coils over time. highintermediate	high	intermediate
ER CO	The condenser temperature sensor has failed or is out of range. On some LG models, ER CO also indicates a communication error between the main control board and a secondary board. highintermediate	high	intermediate
ER IF	The ice maker temperature sensor has failed or is reading outside its expected range. The control board cannot accurately monitor ice maker temperature, so ice production stops as a safety measure. moderateintermediate	moderate	intermediate
FF E	The freezer evaporator fan motor has stopped running or the control board cannot detect its operation. Without this fan, cold air cannot circulate from the freezer to the fresh food compartment. highintermediate	high	intermediate
FREEZING	A Lg refrigerator freezing food has specific causes related to Lg's design and component choices. mediumintermediate	medium	intermediate
HUB	Reference hub covering all LG refrigerator fault codes displayed via Smart Diagnosis on French door, side-by-side, and bottom-freezer models. lowbeginner	low	beginner
ICE-MAKER	A Lg refrigerator ice maker not working has specific causes related to Lg's design and component choices. mediumintermediate	medium	intermediate
