LG Refrigerator rF Error
LG's FF/rF article publishes an ice-melt procedure for FF only. None is published for rF, so this page does not borrow FF's melt — the difference is LG's, and it is printed rather than smoothed over.
What to check first
- Read the code exactly: rF / Er rF = refrigerator compartment fan fault (not FF).
- Do LG's one power reset: unplug or trip the breaker, reuse after about 5 minutes.
- Do not borrow FF's melt — LG publishes it for FF only.
- Same code repeated → LG service technician for an accurate diagnosis.
An rF code (written ER(E) rF in LG's per-code article) is a refrigerator fan fault: the refrigerator compartment fan motor does not operate normally. LG's analog list gives the fan's job — it circulates cold air in the refrigerator; if the fan is blocked, the compressor overworks to maintain temperature, internal temperature increases and performance is reduced. LG files rF in the same article as FF but gives it a shorter treatment: one reset, then service. This page mirrors that exactly.
Safety first
- The refrigerator fan sits behind the compartment's rear panel — internal parts territory. LG's Er guide warning applies: do not disassemble the refrigerator or replace internal parts yourself.
- Stop condition: stop using the machine and unplug it — and do not run it again until it has been checked — if you smell burning, see smoke, find damaged electrics (a scorched plug, a melted or cut cable), or water is leaking in quantity.
Common causes
The fan motor does not operate normally
The only cause LG's article states for rF. It publishes no ice-lock case for this fan (that case belongs to FF), so none is printed here.
Blocked airflow, rising temperatures
LG's list describes the consequence: a blocked refrigerator fan makes the compressor overwork, the internal temperature increases, and performance drops — the warm-fridge symptom behind most rF calls.
Step-by-step checks
- Note the exact coderF, not FF: the refrigerator compartment fan, not the freezer's. On some displays it appears as E rF or Er rF.
- Do LG's one power resetUnplug the power cord, or trip the exclusive circuit breaker, to reset the power — then use the refrigerator again after about 5 minutes (LG US article).
- If the same code repeats, stopLG's line for this code: if the same symptom and the same inspection code are repeated, it is necessary to have it checked by an LG service technician for an accurate diagnosis.
When to call a technician
rF is a one-reset code in LG's own documentation, then a technician's diagnosis. Quote the exact code (rF / Er rF) when you call — and do not let it be logged as FF; they are different fans with different procedures.
Model differences
| What you have | What changes |
|---|---|
| Er / E prefix forms | rF, E rF or Er rF depending on the display — LG's article writes it ER(E) rF. |
| rF vs FF | rF is the refrigerator compartment fan (reset only). FF is the freezer fan, for which LG also publishes an ice-melt procedure. |
One-page checklist — rF
- Code read exactly (rF / Er rF — not FF)
- One power reset done (unplug or breaker, about 5 minutes)
- Code repeated → LG service technician

Frequently asked questions
Can I do the doors-open melt for rF, like FF?
LG does not publish it for rF. The melt in LG's article answers FF's ice-locked fan motor; for rF the article states one cause (the motor not operating normally) and one owner step (the reset). Borrowing FF's procedure would be inventing an LG instruction, so this page doesn't.
Is rF a breakdown?
It is a real fault code. LG's treatment is short — one reset, then a service technician if the same code repeats — which makes rF a service-led code in practice.
