LG codes E FF and E rF identify freezer or refrigerator fan trouble, often after frost prevents a fan from turning. Protect food first and avoid repeated power cycling. The checks below concern controls, ice, filters and accessible compartments only; sealed-system, wiring and fan work belongs to qualified service. What the alert means: The control board sees abnormal fan feedback; frost can obstruct the blades, but wiring or the fan motor may also be responsible. What to distinguish first: E FF points to the freezer fan and E rF to the refrigerator fan; record the exact letters before resetting power. 1. Confirm the exact symptom — The control board sees abnormal fan feedback; frost can obstruct the blades, but wiring or the fan motor may also be responsible. 2. Prepare safely — Keep the doors closed, move perishable food if needed and disconnect power only for the single reset described below. 3. Apply the official check — Disconnect power for about five minutes once, restore it and listen without opening panels; keep doors closed while temperatures recover. 4. Interpret one retest — If the code returns or cooling falls, move perishables and arrange LG service rather than repeatedly cycling power. The official LG procedure identifies this exact symptom and supports the checks above. Do not chip ice with sharp tools, heat plastic parts or remove electrical panels. Arrange service if cooling is lost, water reaches wiring, a fan error returns or the leak cannot be contained.

Next step
Repair, replace a part, or arrange a diagnosis?
Use the checks and stop conditions above to choose a cautious next step. A symptom alone never proves that the appliance has failed.
Resolve it without buying anything
Complete the 4 user-accessible checks in order. If normal operation returns and no warning sign remains, no replacement is indicated.
Replace only the confirmed part
If the checks isolate a worn or blocked component, match its complete reference to the exact appliance model before ordering.
This guide does not identify a replacement part. Do not order a generic component from the symptom alone.
Arrange a diagnosis before replacing the appliance
Stop at any warning sign listed above. A qualified diagnosis should confirm that repair is unsafe, unavailable or uneconomical before an appliance replacement is considered.
