Common LG refrigerator codes
22
LG Refrigerator Error 22: Compressor Relay Problem
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.

33
LG Refrigerator Error 33: Compressor Relay Problem
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.

67
LG Refrigerator Error 67: Door Obstruction or Door Not Closing Correctly
LG refrigerator error 67 usually means a door is obstructed, not closing fully, or not sealing correctly.

Ad
LG Refrigerator Error Ad: Door Motor Failure — Auto-Close or French Door Motor
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: Condenser Fan Feedback Error
LG refrigerator error CF usually means the rear condenser fan is not spinning normally or the control cannot confirm that it is running.

CH E
LG Refrigerator Error CH E: High-Side Refrigerant Leak Detected
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.

Symptom entry points
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.
Model-family guidance
What can vary by model
- LG refrigerator display wording and code formats can vary by series.
- If your model behaves differently, check the owner manual before trying any deeper maintenance step.
- Some models may display the same fault as Ad, dr.
- Rear-panel access and condenser-fan layout vary by LG refrigerator family, but CF still points first to the rear cooling-fan path.
Frequently asked questions
Appliance-level FAQs add supporting context without forcing users into long-form content.
Where should I start with LG refrigerator error codes?
Start with the refrigerator overview page, then use the full error code list or open the code that matches your display. Each page gives a quick meaning, safe checks, and escalation guidance.
Are all LG refrigerator codes the same across models?
Not always. Meanings can vary by series or model, so the guidance here stays conservative and recommends checking the manual for model-specific wording.
When should I stop troubleshooting and contact support?
If the same warning returns, the appliance is leaking, will not run safely, or the next step would require invasive work, it is best to turn it off and contact LG support or a qualified technician.
