Freezer
F6
The F6 error code on an LG freezer indicates a fault with the ice maker’s fan motor circuit — specifically that the freezer’s fan is not spinning correctly or is not being detected by the control board. Left unresolved, it can cause temperature instability and food spoilage.
What does this error mean?
LG’s F6 code points to a problem with the ice maker fan motor — the small fan that circulates cold air around the ice-making compartment. The control board is detecting either no signal from the fan, or an abnormal speed reading. This usually means the fan has seized, its wiring has failed, or the control board itself has stopped communicating with it correctly.

🔍 Likely causes
🛠️ Step-by-step fix
Step 1 — Power cycle the freezer: Unplug it from the wall for 5 minutes, then plug it back in. If the F6 code clears and does not return within 24 hours, the fault was a temporary glitch.
Step 2 — Inspect for ice build-up: Remove any food from the freezer and locate the ice maker fan (usually behind a panel in the ice maker compartment). If you can see or feel ice packed around the fan blades, perform a manual defrost — unplug the unit and leave the door open for 24–48 hours with towels on the floor to absorb water.
Step 3 — Check the fan blades manually: With the freezer unplugged, try to rotate the fan blades by hand through any accessible gap. They should spin freely. If they feel stiff or won’t move at all, the motor has likely seized and needs replacing.
Step 4 — Inspect visible wiring: With the freezer still unplugged, check for any obviously loose, burnt, or disconnected wiring connectors near the ice maker fan. Re-seat any loose connectors firmly. Do not open sealed electrical components.
Step 5 — Replace the ice maker fan motor: If the fan is seized or confirmed faulty, order a compatible replacement motor using your LG model number (found on the rating plate inside the door). Fan motors are widely available online for £20–£45. Fitting requires removing the ice maker panel — straightforward for a confident DIYer with basic tools.
Step 6 — If the fault persists after a new fan motor: Stop DIY at this point. The control board may be faulty, which requires a qualified appliance engineer to diagnose and replace safely.
📞 When to call a professional
Call a qualified appliance engineer if the F6 error returns after a new fan motor has been fitted, or if you find burnt wiring or signs of electrical damage. Tell the engineer: ‘My LG freezer is showing an F6 error code, which I understand relates to the ice maker fan motor circuit.’ This saves diagnostic time and may reduce your call-out cost.
⚖️ Repair or replace?
A professional repair for an F6 fault typically costs £80–£160 including parts and labour in the UK. If your LG freezer is under 7 years old and the fault is confirmed as just the fan motor, repair is almost always the better value option. If the control board needs replacing on a unit over 8–10 years old, the repair cost (£150–£250+) often approaches the cost of a new mid-range freezer, making replacement worth serious consideration.
