What each LG LFC22770 error code means and what to do.
Error codes
| Code | Meaning | Owner action |
|---|---|---|
| 22, 33 | Problem with the compressor relay. | |
| 67 | Gap in the door or an object restricting door closure. | Check for an object blocking the door and that the door closes fully. |
| 88 | Display test — unit functioning properly. | None. |
| Ad | Auto-door motor does not reach the maximum/home position within 5 seconds. | |
| AS | Auto-door motor reed switch in the open state. | |
| C1 | Communication error between the LCD display and the dispenser. | |
| CF | Condenser fan motor error — fan that cools the compressor compartment not operating (feedback signal < 65 seconds during fan operation). | Unplug the power cord (or trip the breaker), wait about 5 minutes, restore power. Monitor whether the code reappears after ~3 hours. |
| CH | High-side refrigerant leak / sealed-system fault (faulty valve, abnormal sensor readings). | |
| CL | Low-side refrigerant leak / sealed-system fault. | |
| CO | Communication error between the main control board and the display PCB (unstable power, wire disconnection or component failure). | Unplug the power cord (or trip the breaker), wait about 5 minutes, restore power. |
| dH | Defrost failure — the defrost cycle did not raise temperature sufficiently (LG: > 1 hour / 80 minutes). Causes named by LG: ice accumulation, blocked drain, thermal fuse, heater disconnection, main PCB. | Unplug for ~2 minutes to reset (code list). If ice is present: Unplug the unit, open the doors fully and let ice melt (LG: 8+ hours on the code list; 1 day in summer / 3 days in winter on the FF/dH articles); let water drain to the drain tray. Move food if spoilage is a concern. |
| dr | Door motor does not reach the maximum/home position within 5 seconds. | |
| dS | Defrost sensor short or disconnection; evaporator ice blockage risk. | |
| EID | Freezer-compartment ice maker sensor failure. | |
| EIU | Freezer-compartment ice maker assembly failure. | |
| FF | Freezer fan motor error — no signal from the freezer fan motor; frost/ice buildup can lock the fan. | Unplug the power cord (or trip the breaker), wait about 5 minutes, restore power. If frost is suspected: Unplug the unit, open the doors fully and let ice melt (LG: 8+ hours on the code list; 1 day in summer / 3 days in winter on the FF/dH articles); let water drain to the drain tray. Move food if spoilage is a concern. |
| FS | Freezer temperature sensor short or disconnection. | |
| FU | Cycle error — freezer temperature does not fall below 3.5°C within 10 minutes. | Unplug the power cord (or trip the breaker), wait about 5 minutes, restore power. Check temperature settings and door seals. |
| gF | Water flow sensor error or low water pressure (closed tap, kinked hose, pressure). | Check the water tap is open, the hose is not kinked, and increase water pressure. |
| HI | High ambient temperature warning (above +50°C); performance may be affected. | Not a fault; performance warning. |
| HS | Humidity sensor short or disconnection. | |
| IF | Ice maker fan error — blockage or fan fault; frost buildup possible. | Unplug the unit, open the doors fully and let ice melt (LG: 8+ hours on the code list; 1 day in summer / 3 days in winter on the FF/dH articles); let water drain to the drain tray. Move food if spoilage is a concern. |
| IS | Ice maker sensor error / ice maker fan motor or sensor disconnection; ice is no longer dispensed. | |
| It | Ice maker motor error / defect in the ice maker. | |
| L0 | Low ambient temperature warning (below −10°C); performance may be affected. | Not a fault; performance warning. |
| Od | Wi-Fi modem or communication error. | |
| OF F | Display off / demo (showroom) mode — cooling is disabled. | Press and hold REFRIGERATOR and ICE PLUS for 5 seconds (button pair varies by model). |
| r2 | Refrigerator temperature sensor (R2, lower) fault. | |
| rF | Refrigerator compartment fan motor error — fan motor not operating normally; frost buildup possible. | Unplug the power cord (or trip the breaker), wait about 5 minutes, restore power. If frost is suspected: Unplug the unit, open the doors fully and let ice melt (LG: 8+ hours on the code list; 1 day in summer / 3 days in winter on the FF/dH articles); let water drain to the drain tray. Move food if spoilage is a concern. |
| rS | Refrigerator temperature sensor (R1, upper) short or disconnection. | |
| rT | Ambient (room) temperature sensor short or open. | |
| Sb | Sabbath mode is active (lights, alarms and dispenser disabled; auto-off after 96 hours). | Press and hold Freezer and Wi-Fi for 3 seconds (varies by model). |
| SS | Pantry / water tank sensor short or open. | |
| tt | Water tank error — tank missing, misaligned, or sensor malfunction. |
