The directory currently provides no verified error-code table for this model. Check the official model manual and symptom advice; do not apply generic codes from another appliance.
Safety first
Do not remove covers, open electrical components or work on refrigerant lines. If there is smoke, sparking, a burning smell, damaged wiring or water near electrical parts, stop and disconnect power only when it is safe. Contact an authorised technician. A normal diagnostic message is different from an immediate hazard.
Quick help
| What you see | Safe next step | When to request service |
|---|---|---|
| Unfamiliar code or warning | Write down the exact characters, check the rating-label suffix, and contact LG New Zealand. The matching LG owner’s manual says to keep the power on when an error code appears and report the exact code to LG, unless an immediate electrical or fire hazard makes disconnection necessary. See Failure Detection guidance. | Promptly if the error is indicated; immediately if cooling fails or an electrical hazard appears. |
| Food becoming warm | Check the actual compartment temperature with a suitable thermometer. Review New Zealand Ministry for Primary Industries food storage guidance; a temperature setting is not a measured food temperature. | If safe storage temperatures are not maintained, protect the food and arrange service. |
| Door alarm or poor closure | Check that nothing prevents the door from closing; inspect the seal visually and shut the door completely. Do not force hinges or remove panels. | If the alarm continues with doors properly closed, or the gasket is damaged. |
For food that may have warmed, use New Zealand Ministry for Primary Industries food storage guidance; follow regional food-safety advice rather than relying on the display setting alone.
Error codes and display messages
No specific error-code family below has been confirmed applicable to LG GF-B505MBL in New Zealand. This is an evidence limit, not proof the codes cannot appear. LG NZ confirms an internal LED display, but the matching owner’s manual does not provide the seven code families as a verified model-specific list.
General LG refrigerator code families (unconfirmed for this model)
The next table is for recognising a display pattern only. The sources are LG USA general guidance, not New Zealand documentation. Slash-separated text is grouped for searching and does not prove code spellings or functions are interchangeable.
| Display family | Meaning in LG general guidance | Source and model status |
|---|---|---|
FF / ErF | LG USA describes FF as a freezer-fan fault; the grouped ErF spelling has not been validated for this unit. | LG USA general guidance Not confirmed for GF-B505MBL |
IF / EIF / 1F | LG USA describes IF as an ice-maker fan fault. This does not establish that EIF and 1F are equivalent on every model. | LG USA general guidance Not confirmed for GF-B505MBL |
CF / Er CF | LG USA describes CF / E CF as a condenser or mechanical-compartment fan fault. The grouped typography may vary. | LG USA general guidance Not confirmed for GF-B505MBL |
CO / Er CO | LG USA describes CO / E CO as a control-to-display communication fault. | LG USA general guidance Not confirmed for GF-B505MBL |
FS / rS / dS / rdS | LG USA references freezer, refrigerator and defrost sensor errors. These grouped spellings have different meanings and are not interchangeable. | LG USA general guidance Not confirmed for GF-B505MBL |
ECH / ECL | LG USA lists E CH and E CL as high-side and low-side refrigerant-cycle indications; the unspaced forms have not been confirmed. | LG USA general guidance Not confirmed for GF-B505MBL |
Lo / HI | LG USA describes low and high ambient-temperature warnings; thresholds and presence depend on the model. | LG USA general guidance Not confirmed for GF-B505MBL |
Do not attempt a reset or component repair from this table. The manual says to report an indicated error code to LG rather than turning power off just to clear it. This is not a reset procedure.
Common problems
What you notice: cooling seems weak or food temperature rises.
What to check: LG owner’s manual MFL71782482 describes safe non-invasive checks: verify that the appliance has power, the doors close properly, stored food does not obstruct airflow, and the temperature setting is suitable. Use its “Before Calling for Service” section (read the matching manual).
When to stop: If safe food temperatures cannot be maintained, there is visible damage, or the problem persists, contact LG.
What you notice: an open-door alarm, an unfamiliar sound or moisture by the doors.
What to check: Look for blocked door closure and items pressed against the seal; observe without dismantling components.
When to stop: Persistent alarm, severe unexplained noise, or an electrical warning needs assessment by LG.
Product-specific feature: The listing identifies 530L matte-black slim French-door model; no ice or water dispenser. Do not follow ice-maker fan or dispenser repair advice just because a general LG code reference mentions those components.
