LG Refrigerator rF error code: meaning and what to do

Most LG sources describe rF as an abnormality with the refrigerator compartment fan motor.

Applies to: LG refrigerators covered by the US support page · United States. Scope and limitations

Safety: Keep food-safety risk in mind if cooling is reduced.

First step: Check actual compartment temperatures with an appliance thermometer and protect food using the food-safety checklist. If cooling or safe food storage is uncertain, request qualified service instead of clearing the display.

What to check first

Use should be limited to documented owner-level checks or retry steps, not normal operation as a workaround.

Basic checks

Check actual compartment temperatures with an appliance thermometer and protect food using the food-safety checklist. If cooling or safe food storage is uncertain, request qualified service instead of clearing the display.
Record the full rF display and model. Observe only through normal access; do not remove fan covers, probe wiring or work on the sealed refrigerant system.

Reset or retry steps

Match the full model to its owner manual before choosing a recovery path. The two LG articles give different procedures; the display or article date alone does not choose between them. If the applicable path is unclear, request LG service.
In the dedicated FF/rF article, the rF section describes power off at the safe dry plug or dedicated breaker and restoring power after about five minutes. This is one source-specific option, not permission to ignore unsafe cooling, water or electrical warnings.
Separately, the general code list describes an unplugged, food-removed, doors-open defrost of at least eight hours for rF, with towels for meltwater and a further 24–48 hours for normal operation after reconnecting. Do not return food based on elapsed time alone; verify safe temperatures. Use this only when the exact model manual confirms that path.
FaultCodeLab limits recovery to one applicable, otherwise safe owner path. Do not chain or repeat resets and thaws, add heat, chip ice or open fan/electrical areas. Request service for recurrence, unsafe food storage or unclear model applicability.

When to call a technician

LG requires inspection for abnormal refrigerator fan operation; request service if the same symptom/code repeats, cooling is unsafe or any safe recovery condition cannot be met.

Before approving a paid visit, check warranty status and reviewquestions to ask before repair.

Can I keep using it?

Food safety first

You can usually keep it powered while checking temperatures, but food safety comes first if cooling is weak or power was interrupted.

Safe next step: Check actual compartment temperature, move perishable food to safe cold storage if needed, and use the model manual for any further steps.
Stop when: Food is thawing, temperatures are unsafe, the unit is not cooling, or electrical symptoms appear.

Electrical warning: stop and verify

Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.

Safe next step: Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
Stop when: Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.

Safety boundaries

Safe first

Match the exact brand, appliance type, and displayed code first.
Use the model manual as the final authority for access steps.
Disconnect power before any service-access step.

Do not do this

Do not use other cycles as a workaround unless the manual allows it.
Do not bypass locks, float switches, leak sensors, or other safety systems.

Common causes include

Refrigerator fan motor not operating normally; this does not identify a failed replacement part.
The general code list also names frost buildup as a possible fan obstruction.

FAQ

What does LG Refrigerator code rF usually mean?

Most LG sources describe rF as an abnormality with the refrigerator compartment fan motor. Model context matters: LG documents ER/E rF as refrigerator-compartment fan motor behavior.

Can I keep using the refrigerator with code rF?

Limit use to the owner-level checks described here and in the model manual. Stop using the appliance if the code returns, the appliance behaves abnormally, or a safety warning applies. Keep food-safety risk in mind if cooling is reduced.

When should I call a technician for LG rF?

LG requires inspection for abnormal refrigerator fan operation; request service if the same symptom/code repeats, cooling is unsafe or any safe recovery condition cannot be met. A qualified technician may check the listed symptoms and source guidance against the model's service information before treating any part as failed.

Model notes

LG documents ER/E rF as refrigerator-compartment fan motor behavior.
The dedicated article gives an approximately five-minute power reset. Its long seasonal thaw is under FF; a separate general code list provides an eight-hour food-removed defrost under both FF and rF. Use the exact model manual to choose, rather than importing an adjacent section or assuming one duration is universal.
