Most searched LG refrigerator codes
| Code | Meaning |
|---|---|
| 6 Blinks | Compressor current overload trip — the inverter board's LED blinking 6 times means the drive detected excessive compressor current and shut the compressor down to protect it (LG's service manuals head the section 'Over Current Trip & LED 6 blink'). Communication failure is a different pattern in the same chart: 8 blinks. [Corrected 2026-10-28, verification pass: LG service manuals LRFLC2706* + LFX25978/LFX28978.] |
| CF | Condenser fan error — displayed as Er CF / E CF (the E is the panel's error marker). LG: a CF error appears if the fan motor which disperses heat from the mechanical compartment (compressor) at the back of the refrigerator does not operate due to an abnormality. LG calls it a mechanical compartment fan motor defect error. |
| CH | High-side refrigerant leak (Er CH, also shown CH E / E CH) — LG's service chart defines CH as a leak on the high-pressure side of the sealed system. It is NOT a communication error: LG's board-communication code is CO (Er CO). [Corrected 2026-10-28, verification pass: LG service manual LRFLC2706* error display chart.] |
| CL | Not a published LG refrigerator fault code. LG's refrigerator manuals document CL's home territory as a panel state — the Lock (Child Lock / Control Lock) function, released by holding the Lock button for about 3 seconds — while LG refrigerator faults are reported in the ER(E) + letters system (Er CF, Er FF, Er rF and their family). The widely searched pairing 'CL E' is not published as a fault in the LG help library or the owner manuals checked for this page, and this page does not repeat the refrigerant-leak meaning third-party sites attach to it as if it were LG's: what is documented, and what to do about each reading, is separated below. |
| D5 | Defrost sensor error (Er D5 / dS family) — the defrost temperature sensor is faulty. |
| DH | Defrosting failure — the refrigerator has failed to defrost properly (displayed F dH for the freezer side, r dH for the refrigerator side, or Er dH). |
| F5 | Freezer temperature sensor error — F5 is how segmented displays render Er FS, LG's freezer sensor code ('defect of freezer sensor: shortcircuit or disconnection of freezer sensor' in LG's service chart). The refrigerator-compartment sensor is a separate code, Er rS — not this one. [Corrected 2026-10-28, verification pass: LG service manual LRFLC2706* error display chart.] |
| FF | Freezer fan error — the freezer evaporator fan motor is not running correctly (Er FF). |
| FFE | Freezer fan error variant (Er FFE on some LG platforms) — the freezer evaporator fan is reporting a fault. |
| IF | Ice-maker fan error — an issue with the ice maker fan, in LG's own guidance caused by frost or ice buildup around it. Displayed as IF, IF E / E IF (Er IF), Er IFE and paired by LG with F1 (read 1F on segmented displays) — all the same ice-maker fan code family. |
| RF | Refrigerator fan error (Er RF) — the fresh-food evaporator fan is not running correctly. |
