Full Error Code List

LG refrigerator error codes

Use this page when you already know the display code or want to compare LG refrigerator meanings quickly by severity.

How to use this list

Use the table to confirm the exact code, then open the detail guide for the safest first checks, model notes, and next-step options.

What the list is best for

  • Matching the exact display code before you act.
  • Comparing severity and meaning side by side.
  • Spotting closely related warnings that users often confuse.

What happens on the detail page

  • Quick answer and severity guidance.
  • Symptom-based first checks where the content supports it.
  • Model and display notes plus trust and source context.

LG refrigerator code table

Scan by code, meaning, and severity, then open the exact detail page when you need step-by-step guidance.

22
The refrigerator has detected a fault with the compressor relay circuit. This is closely related to error 33 and indicates the same class of compressor start or run fault on certain LG model ranges.
high severity
33
The refrigerator has detected a fault with the compressor start relay or the compressor circuit. The compressor may not be starting or running correctly, putting the cooling system at risk.
high severity
67
LG refrigerator error 67 usually means a door is obstructed, not closing fully, or not sealing correctly.
low severity
Ad
The automatic door closure motor (used on French door or InstaView models with a motorized door feature) has stopped working. On models with a door-in-door design, this affects the inner door panel operation. The dr variant indicates the same fault on some model lines.
medium severity
CF
LG refrigerator error CF usually means the rear condenser fan is not spinning normally or the control cannot confirm that it is running.
high severity
CH E
The refrigerator's leak detection system has identified a refrigerant leak on the high-pressure side of the cooling circuit. Refrigerant is escaping, reducing cooling capacity and potentially posing an environmental hazard.
high severity
CL E
The refrigerator's leak detection system has identified a refrigerant leak on the low-pressure (evaporator) side of the cooling circuit. Cooling capacity is reduced and food safety is at risk.
high severity
CO
The main control board and one or more sub-boards (such as the display board or inverter board) cannot communicate. The refrigerator's internal electronics have lost contact with each other.
high severity
dH
LG refrigerator error dH usually means the automatic defrost cycle is not clearing frost from the evaporator in the expected time.
medium severity
dS
The defrost sensor (thermistor that monitors evaporator temperature during the defrost cycle) has either shorted or become disconnected. Without a valid sensor reading, the control board cannot safely manage the defrost cycle.
medium severity
EID
The temperature sensor inside the freezer ice maker has failed or is reading outside the expected range. The refrigerator cannot monitor the ice maker tray temperature and has disabled ice production to prevent a malfunction.
medium severity
EIU
The ice maker assembly has reported a general internal fault. The unit is not functioning correctly and ice production has stopped.
medium severity
FF
LG refrigerator error FF usually means the freezer evaporator fan is not circulating cold air through the cabinet properly.
medium severity
FS
The freezer temperature sensor (thermistor) has shorted or become disconnected. The control board cannot monitor freezer temperature and cannot regulate the cooling cycle correctly.
medium severity
gF
The refrigerator's water flow sensor has detected insufficient water flow to the ice maker and water dispenser. The sensor is not registering adequate pressure or flow rate from the household water supply.
medium severity
IF
LG refrigerator error IF usually means the ice maker compartment fan is not running normally.
medium severity
IS
The ice maker compartment fan or its temperature sensor is not functioning correctly. The ice maker fan circulates cold air around the ice tray — without it, ice production slows or stops and ice quality deteriorates.
medium severity
iT
The ice maker has reported a general internal defect. The refrigerator's diagnostics have identified a fault within the ice maker mechanism that is outside the scope of a simple sensor or fan error.
medium severity
rF
LG refrigerator error rF usually means the refrigerator-section fan is not moving air correctly.
medium severity
rS
The fresh food compartment temperature sensor (thermistor) has shorted or become disconnected. The control board cannot accurately monitor refrigerator temperature and may not cool the section correctly.
medium severity

Common symptom shortcuts

These clusters give users another way into the list when they know the symptom but not the code.

Leaks, fill, and water-path issues

  • CH E - The refrigerator's leak detection system has identified a refrigerant leak on the high-pressure side of the cooling circuit. Refrigerant is escaping, reducing cooling capacity and potentially posing an environmental hazard.
  • CL E - The refrigerator's leak detection system has identified a refrigerant leak on the low-pressure (evaporator) side of the cooling circuit. Cooling capacity is reduced and food safety is at risk.
  • EIU - The ice maker assembly has reported a general internal fault. The unit is not functioning correctly and ice production has stopped.

Door, latch, and lock warnings

  • 67 - LG refrigerator error 67 usually means a door is obstructed, not closing fully, or not sealing correctly.
  • Ad - The automatic door closure motor (used on French door or InstaView models with a motorized door feature) has stopped working. On models with a door-in-door design, this affects the inner door panel operation. The dr variant indicates the same fault on some model lines.
  • CF - LG refrigerator error CF usually means the rear condenser fan is not spinning normally or the control cannot confirm that it is running.

Sensor and temperature faults

  • dH - LG refrigerator error dH usually means the automatic defrost cycle is not clearing frost from the evaporator in the expected time.
  • dS - The defrost sensor (thermistor that monitors evaporator temperature during the defrost cycle) has either shorted or become disconnected. Without a valid sensor reading, the control board cannot safely manage the defrost cycle.
  • EID - The temperature sensor inside the freezer ice maker has failed or is reading outside the expected range. The refrigerator cannot monitor the ice maker tray temperature and has disabled ice production to prevent a malfunction.
