Quick answer: An LG fridge warming while the freezer stays cold, or buzzing behind the freezer panel, is almost always the evaporator (freezer) fan motor. A hot back and a compressor that never rests points to the condenser fan motor; frost spreading over the freezer back wall points to the defrost thermostat. Oz Appliance Spares stocks these LG fan motors and defrost parts in Australia and dispatches from Sydney the day you order (12pm Sydney cut-off). Match the full model number on the sticker inside the fridge, letters included.

The LG fault that starts as a noise
It usually goes like this. The French-door LG starts a low buzz from the freezer at night. A week later it is a rattle. Then it goes quiet, the milk is warm, and the freezer is still rock solid. That is the evaporator fan motor dying behind the freezer’s back panel.
LG fridges are the fridge line Australians most often repair rather than replace, because what fails is a small DC motor or a clip-on thermostat, not the compressor. The LG fridge loud noise guide covers the sound itself. This page is the parts front door to our refrigerator and freezer parts range.

GF, GB, GN, GS: what the LG model prefix tells you
The first two letters of an LG model number describe the cabinet, and that alone narrows the part list:
- GF is French door (two fridge doors over a freezer drawer): GF-B530BL, GF-V570MBLC.
- GB is bottom mount (one fridge door over a freezer door): GB-335PL.
- GN is top mount (freezer on top): GN-422FW.
- GS is side by side: GS-L635PL.
- GT and GR are top-mount and older numbers, still worth fixing.
The letters after the numbers (BL, PL, WL, MBL) are mostly finish, but one finish can carry a different fan or shroud, so quote the whole string. Every LG model we list sits under LG models, and the LG parts range holds the lot by part type.
Evaporator (freezer) fan motors: the part that fails most
The evaporator fan sits behind the removable back panel inside the freezer and pushes air over the coil, then up a duct into the fridge. When it slows, the freezer stays cold because it is sitting on the coil, but the fridge starves. Ice on the blades is the scrape; a worn bearing is the buzz. The fan does not fix itself, though it will sometimes go quiet for a day just to give you hope.
Beyond the table, by series:
- GF French door on the L570 family in the MBNL or PNL finish: LG Fridge Evaporator Fan Motor DC12V GF-L570MBNL GF-L570PNL.
- Older GT top mounts: LG Fridge Evaporator Fan Motor GT-1S GT-2S GT-2W GT-3S GT-4S GT-4W GT-5B GT-5S.
- Earlier LG fridges with a two-speed freezer fan: LG FRIDGE EVAPORATOR (Freezer) FAN MOTOR 2 Speed. Send the model number and we will confirm.
Before ordering, unplug the fridge, empty the freezer and take the back panel off. Heavy ice around the fan and coil means the defrost side is the problem and a new fan will ice up again in a fortnight; a clean coil with a seized or noisy fan means the motor. The LG fridge not cooling guide covers the full sequence, and the broader fridge not cooling but freezer works guide applies to LG too.
Condenser fan, defrost parts and DC motor assemblies
Condenser fan motor. Bottom rear beside the compressor, behind the cover. When it stops, the compressor runs hot and long, both compartments drift warm and newer models throw Er CF. Unplug, remove the cover and spin the blade by hand: stiff or wobbly means the motor.
Defrost termination thermostat. A clip-on disc on the evaporator that tells the board the coil is clear. When it fails open the heater never runs, ice grows week by week, airflow chokes and you get the warm fridge with an iced-up freezer wall. A $10–20 part and the cheapest fix on this page; Er dH points the same way.
Temperature sensors. Er rS, Er FS and Er dS are the fridge, freezer and defrost sensors. We do not hold every LG sensor, so send the model number and the code for an honest yes or no. The LG fridge error codes guide and the LG Er IF guide cover the rest.
DC motor assemblies. LG lists some fan and damper drives as a plain DC motor assembly. If your model number is in the listing, that is the one: LG FRIDGE DC MOTOR ASSEMBLY GF-B530BL GF-B590BLE GF-LN500PL GF-V570MBLC, or the rated-speed version, LG Fridge DC Motor Assy 1920RPM 2.28W. Match the model, not the look of the old motor.
Inverter and main boards. Fit after diagnosis, not on a guess: only when the fan tests good and the board is not sending it power.
Two straight answers: door seals and the sealed system
We do not stock LG fridge door seals; a split gasket goes through LG or a repairer. The sealed system (compressor, gas, leaks, capillary) is licensed refrigeration work in Australia, and no part here touches it. The fridge spare parts in Australia guide covers what is worth fixing on any brand.
Where the LG model sticker is and how to match it
Open the fridge door and look at the inside left wall, around the top crisper. The sticker carries the word Model followed by a string starting GF-, GB-, GN-, GS-, GT- or GR-. Copy the whole thing, letters at the end included, and photograph it. The LG model number guide shows where it hides on each cabinet type.
Search that model number on the site and buy the listing that names it. Not there, or between two listings? Send it through the contact page with the symptom; we check the match before you order, not after.
DIY or repairer?
Fan motors and the defrost thermostat are jobs most Australians can do at home: unplug at the wall, thaw the freezer, remove the back panel, unclip the fan, swap the connector. A fan motor is $45–90; a defrost thermostat $10–20. A repairer’s call-out and diagnosis typically runs $100–165 before any part, so a first-time DIY on a fan leaves you well ahead.
Call a repairer when the compressor is silent or clicks and stops (inverter drive or sealed system); when the fan tests fine and the fault is upstream on the board; or when a GS side by side’s water and ice module is in the way. Never run the fridge with the panel off and the blade exposed, and never bypass a door switch to watch the fan.
Frequently asked questions
Q: Why is my LG fridge warm but the freezer still cold?
A: The freezer holds the evaporator coil and stays cold on its own; the fridge only cools when the evaporator fan pushes air up the duct. A slow, iced or dead fan motor, or a defrost thermostat that has let ice choke the coil, gives that split. Check for ice first, then the fan.
Q: What do GF, GB, GN and GS mean on an LG fridge?
A: Cabinet type: GF French door, GB bottom mount, GN top mount, GS side by side; GT and GR are top-mount and older numbers. The full model number on the sticker is what you match.
Q: Do you stock LG fridge door seals?
A: No. Send the model number through the contact page if you want current options checked, but do not expect a yes.
Q: Can I replace an LG fridge fan motor myself?
A: Usually. Unplug, thaw the freezer, remove the back panel, unclip the old fan and plug the new one in. Match the model number to the listing first; LG changes fans between series and finishes.
Q: My LG fridge shows Er FF or Er CF. Which part is it?
A: Er FF is the freezer (evaporator) fan circuit and Er CF is the condenser fan. It is nearly always the motor itself. Test the fan before you consider a board.
The model number on the sticker inside the fridge is the whole game.
