35 error codes

CodeMeaning
1FThe freezer defrost temperature sensor has failed or is reading out of its expected range, preventing the automatic defrost cycle from operating correctly.
highintermediate
1f eThe 1f e code (which honestly looks like If E on most displays) means the ice maker fan motor in your freezer isn't spinning at the speed it should. The control board detected that and shut things down before the motor could burn out completely.
moderateintermediate
CFThe CF code fires when the control board detects the condenser fan isn't spinning fast enough or isn't spinning at all. That fan's job is to pull air across the compressor and condenser coils to dump heat. No fan means no heat dissipation, and the compressor starts cooking itself from the inside out.
highintermediate
CF EThe 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
CH EThe control board is getting an open circuit, short circuit, or wildly out-of-range resistance reading from one of the compartment temperature sensors. LG French door fridges have multiple NTC thermistors for different zones, and CH E fires when any one of them stops reporting a believable temperature.
moderateintermediate
CLCL isn't actually an error code. It stands for Child Lock, which means the control panel and all the dispenser buttons are locked to prevent accidental changes or little hands from messing with the settings.
lowbeginner
CL ECL E means the main control board lost communication with the door cooling fan, or the fan itself has stopped responding entirely. It's specific to LG French door and side-by-side models with the Linear Compressor system, and it's almost always isolated to the door section, not the main cabinet.
moderateintermediate
COMPRESSORThe compressor pressurizes refrigerant so it can absorb heat from inside the cabinet. When it stops running, refrigerant just sits there and nothing cools. LG's Linear Compressor design cuts down on moving parts but created specific failure points in the piston and valve assembly that ended up triggering a class action settlement.
moderateintermediate
COMPRESSOR-FAILUREThe compressor, basically the pump that circulates refrigerant through your whole system, isn't starting or can't build pressure. Your fans still run fine, but without that pump moving refrigerant around, nothing's actually making cold air and the temperature just keeps climbing.
moderateadvanced
DH FThe 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
ER COThe condenser temperature sensor's either failed or reading outside its normal range. On a lot of LG models, ER CO can also mean the main control board and the inverter board have lost communication with each other. Two different root causes, same error code.
highintermediate
ER IFThe 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
Er CFThe main control board monitors the condenser fan motor's speed at the bottom rear of the unit. When that fan slows down or stops completely, the board triggers Er CF to protect the compressor from overheating. The fan's supposed to run any time the compressor is running, so if it's not spinning, heat builds up fast.
highintermediate
Er CFThe condenser fan motor isn't spinning at the speed the control board expects, or it's stopped communicating entirely. The board detects this through a hall sensor signal. No signal means no cooling cycle, which is the board protecting the compressor from overheating.
highintermediate
Er FFThe control board sent voltage to the freezer evaporator fan motor and got no feedback signal. Either the blades are physically jammed and can't spin, or the motor windings are shot and it's not drawing current the way it should. Simple as that.
highintermediate
Er FFEr FF means the control board detected the freezer evaporator fan isn't spinning at the right speed or isn't spinning at all. That fan pulls air across the cold coils and pushes it into both compartments. No fan, no airflow, no cooling anywhere in the unit.
highintermediate
FFFF stands for Freezer Fan. The control board detected that the evaporator fan motor isn't spinning or isn't sending a feedback signal back. Basically the fan that moves cold air from the freezer coils throughout your fridge has stopped, and the board noticed.
highintermediate
FF EThe 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
FREEZINGThe fridge section is getting too much cold air from the freezer because the electronic damper is stuck open or a thermistor is telling the control board the temperature is warmer than it actually is, so the compressor keeps running when it shouldn't.
moderateintermediate
HUBReference hub covering all LG refrigerator fault codes displayed via Smart Diagnosis on French door, side-by-side, and bottom-freezer models.
lowbeginner
ICE-MAKERThe ice maker isn't completing its harvest cycle. On LG's twist-tray design, a motor physically rotates the tray to eject cubes instead of using a heating element. If the fill, freeze, or twist sequence breaks down anywhere, the whole cycle stops and the bin just sits there empty.
moderateintermediate
IFThe IF code, also shown as Er IF, means the control board is detecting that the ice fan isn't spinning at the right speed, or isn't spinning at all. The board monitors fan RPM through a tachometer signal, and when that signal goes wrong or disappears, it shuts things down to protect the motor.
moderateintermediate
IFThe control board monitors that fan constantly. When it stops spinning at the right speed, or stops completely, it throws the IF code. On some displays it shows up as 1F because the letter I and the number 1 look identical on those seven-segment screens. Either way, same problem, same fix.
moderateintermediate
IF EThe ice maker compartment fan motor has either failed or something's physically blocking it from spinning. It's a separate fan from your main freezer fan. When it stops, the ice maker zone warms up, ice production stops, and the board throws this code to let you know.
moderateintermediate
ISWhen you see IS, or 15 on the display, the control board's lost confidence in the ice maker fan circuit. Either it can't detect the fan spinning at the right speed, or the sensor signal went missing entirely. Something in that ice compartment isn't doing its job.
moderateintermediate
LEAKINGWater is escaping the refrigerator's internal systems, either from the defrost drain trough in the freezer, the pressurized water supply lines, the filter housing, or an overflowing ice maker. Each source looks different and gets fixed differently.
moderateintermediate
LG-SHELF-REPAIRLG refrigerator door shelf repair refers to the process of identifying, removing, and replacing damaged or cracked plastic door bins and gallon containers that have lost structural integrity.
lowbeginner
NOISEYour LG refrigerator is producing sounds outside its normal operating range. Whether it's the evaporator fan hitting ice, the condenser fan wobbling from dust buildup, or the linear compressor doing its characteristic click-on cycle, something's obstructed, worn, or failing inside the unit and it's worth tracking down before it turns into a bigger problem.
moderateintermediate
NOT-COOLINGThe fridge isn't maintaining temperature because something broke in the cooling loop. Either the refrigerant isn't circulating because of a compressor issue, the evaporator coils are frozen solid and blocking airflow, or the fans that move cold air around just aren't running. The fault can be anywhere in that chain.
moderateintermediate
NOT-COOLINGCold air's produced in the freezer compartment but it's not making it into the fridge section. Something's blocking or stopping that airflow, whether it's frozen-over coils, a dead fan, or a damper door that's stuck shut.
highintermediate
PROBLEMSThis covers the most frequent mechanical and electrical failures in LG refrigerators. Basically: why it stops cooling, why it makes noise, and why water ends up on your floor.
moderatebeginner
TROUBLESHOOTINGLG refrigerators have a few recurring weak spots: the linear compressor's internal valves, the evaporator fan that ices over near the back wall of the freezer, and the drain tube that clogs and sends water pooling under your crisper drawers. When something fails, LG's self-diagnostic system usually throws a specific error code to point you right at it.
moderatebeginner
WARM-AIR-SYMPTOMThe fridge can't move heat out of the cabinet anymore. Either the refrigerant isn't circulating because the compressor's gone, the condenser fan stalled so heat's just baking the whole system, or the evaporator coils are buried in ice and no cold air can push through.
highintermediate
WATER-DISPENSERThe dispenser system isn't getting water to the nozzle. The inlet valve might not be opening, the tube running through the freezer door might be frozen solid, or something's blocking flow between the filter housing and the spout.
moderateintermediate
iFeThe IF or iFe code indicates a fault with the icemaker fan motor. This fan is responsible for blowing cold air from the freezer into the icemaker compartment in the door. The code triggers when the control board detects the fan is not spinning at the correct speed or is physically stuck.
