Freezer
F2
If your LG freezer is displaying an F2 error code, it’s telling you there’s a fault with the freezer’s defrost sensor or the ice maker fan motor circuit — a reasonably common issue that ranges from a simple reset fix to a part replacement. It’s not a panic-worthy error, but it does need attention to prevent your food from spoiling or your appliance from working harder than it should. In this guide, you’ll learn exactly what the F2 code means on LG freezers, the most likely causes, safe DIY steps you can try at home, and when it’s time to call in a professional.
What does this error mean?
On LG freezers and fridge-freezers, the F2 error code specifically indicates a fault with the ice maker fan motor (also called the freezer fan or evaporator fan motor). The appliance’s control board has detected that this fan — which circulates cold air over the evaporator coils and throughout the freezer compartment — is either not spinning, spinning too slowly, or drawing an abnormal electrical current. Without this fan working correctly, cold air can’t be distributed evenly, meaning your freezer will struggle to maintain temperature, ice may stop forming, and in some cases frost can build up excessively on the back wall. In certain LG models (particularly older ones and some American-style fridge-freezers), F2 can also relate to a freezer defrost sensor reading an out-of-range temperature — but the fan motor fault is by far the most common trigger across LG’s current and recent product ranges.
Est. repair cost
DIY fan motor replacement: £20–£55 for the part. Professional repair (call-out + parts + labour): £100–£170. Control board replacement (worst case): £150–£250 including labour.
🔍 Likely causes
🛠️ Step-by-step fix
Step 1 – Perform a hard reset first: Unplug your LG freezer from the wall socket (or switch it off at the fuse spur) and leave it completely powered off for 10–15 minutes. Plug it back in and check whether the F2 code has cleared. A temporary sensor glitch or minor control board hiccup can trigger F2, and a hard reset resolves this in a small number of cases. No tools needed.
Step 2 – Check and clear your freezer vents: Open the freezer and inspect the rear and side air vents. If food packaging, bags of ice, or other items are pressed directly against the vents, remove them to restore airflow. Rearrange contents so there is at least a 5cm gap around the vents. Poor airflow is an easy fix that’s often overlooked.
Step 3 – Inspect the door seal for damage: Run your fingers along the entire rubber gasket around the freezer door. Look and feel for any cracks, tears, gaps, or areas where it’s pulling away from the door frame. A faulty seal lets in warm air that freezes and builds up frost rapidly. Replacement LG door seals cost approximately £15–£35 from UK appliance parts suppliers (check your model number at LG’s UK parts page or spares2you.co.uk). Fitting a new seal requires no specialist tools — it clips or slides into a channel around the door.
Step 4 – Defrost the freezer manually: If the error persists after a reset, a build-up of frost around the evaporator fan may be jamming the blade. Empty your freezer (use a cool box or bags of ice to protect food), unplug the appliance, and leave the door open for 24–48 hours to allow all ice to melt completely. Place towels on the floor to catch meltwater. Once fully defrosted, plug back in and monitor for F2 recurrence. This costs nothing and resolves the fault if frost blockage was the cause.
Step 5 – Listen carefully when the freezer restarts: After the defrost and reset, plug the appliance back in and stand quietly next to the freezer for 5–10 minutes. You should hear a faint hum or whirr from the evaporator fan inside the freezer compartment (accessed via the back panel inside the freezer). If you hear nothing, or hear a clicking, grinding, or intermittent sound, the fan motor itself is likely faulty and will need replacing.
Step 6 – Check LG’s SmartDiagnosis feature (if your model supports it): Many LG fridge-freezers manufactured after 2014 include SmartDiagnosis. Open the LG ThinQ app on your smartphone, connect to your appliance, and run a remote diagnosis. This can confirm whether the F2 relates to the fan motor or another component, potentially saving you an unnecessary call-out fee. You’ll need your model number (found on a sticker inside the freezer compartment door frame).
Step 7 – Inspect the fan motor wiring connector (only if confident): WARNING — before attempting this step, unplug the appliance and ensure it is completely powered off. Inside the freezer, remove the rear back panel (usually held in place by 2–4 Phillips head screws). Locate the evaporator fan motor and trace the wiring harness to its connector on the motor. Gently unplug and re-plug the connector to ensure it’s fully seated. Look for any signs of corrosion, burning, or broken wires. If the connector looks damaged, do not attempt to repair it yourself — call a professional. Required tools: Phillips screwdriver, torch.
Step 8 – Replace the evaporator fan motor (DIY-possible but assess your confidence): If you’ve confirmed the fan motor is faulty and the wiring is intact, the motor itself can be replaced by a confident DIYer. LG evaporator fan motors for UK models typically cost £20–£55 from UK spares suppliers. Always order using your exact model number. The motor is usually secured with 2–3 screws and a plug-in wiring harness. Replacement involves removing the back panel, unscrewing the old motor, transferring the fan blade to the new unit, and reconnecting the harness. Video tutorials specific to your LG model are widely available on YouTube. If you are not comfortable working inside the appliance, skip this step and call a professional instead.
Step 9 – If the error returns after fan replacement, stop and call a professional: A recurring F2 after a new fan motor has been fitted points to either a faulty control board or a deeper wiring fault — neither of which is safe or cost-effective to diagnose without specialist tools. At this point, further DIY is unlikely to resolve the issue and could cause additional damage.
📞 When to call a professional
You should call a qualified appliance engineer if: the F2 error returns immediately after a hard reset and manual defrost; you can hear the fan making abnormal noises but are not comfortable removing the internal back panel; your inspection reveals burnt, corroded, or broken wiring; or the error persists after you’ve already replaced the fan motor. When you call, tell the engineer the exact error code (F2), your LG model number (found on the label inside the freezer door frame — it starts with letters like GBB, GSJ, or GML followed by numbers), and what steps you’ve already tried. This will save diagnostic time and potentially reduce your call-out cost. Look for engineers registered with Which? Trusted Traders or with manufacturer-authorised LG service experience. You can find LG-authorised UK service partners via LG’s own website (lg.com/uk/support). Expect a call-out fee of £60–£100 before any parts.
⚖️ Repair or replace?
For most UK homeowners, repair is the right call if your LG freezer is under 8 years old. LG has strong parts availability in the UK, and evaporator fan motors — the most common F2 culprit — are inexpensive and widely stocked. A professional repair (call-out plus fan motor replacement) typically costs £100–£170 all-in, which is excellent value compared to a new under-counter freezer (£200–£350) or a new American-style fridge-freezer (£700–£2,000+). If your appliance is over 10 years old and has had previous faults, the equation changes: repair costs can creep up if the control board is also failing, and older LG models may have slower parts availability. In that scenario, if a professional quotes more than 50% of the cost of a comparable new appliance, replacing is the smarter long-term investment. LG’s build quality is generally solid, and a well-maintained machine in the 3–8 year range is very much worth repairing.
