LG Refrigerator Er gF: The Ice Room Fan Has Failed
Er gF means the fan motor dedicated to the ice making compartment is not running. On LG refrigerators with a dedicated ice room (separate from the main freezer — common on InstaView and French door models), this small fan maintains the precise sub-zero airflow needed for consistent ice production. When it fails, ice production slows dramatically or stops while the rest of the freezer may continue functioning normally.
Which Models Have a Separate Ice Room Fan
Not all LG refrigerators have Er gF capability. This code appears only on models with a separate ice maker compartment that has its own dedicated fan — distinct from the main freezer evaporator fan (Er FF). These are primarily:
- French door models with in-door ice makers
- InstaView models with Craft Ice capability
- Models with the ice maker mounted in the door panel rather than inside the freezer
Standard top-freezer and side-by-side models that use the main freezer fan for ice maker airflow will show Er FF (not Er gF) for fan issues affecting ice production.

What Er gF Affects
The ice room fan serves a narrow purpose: maintaining consistent cold airflow across the ice maker mechanism. When it fails:
- Ice cube production rate drops significantly (50-80% reduction)
- Craft Ice sphere production may stop entirely (requires precise temperature)
- Ice cubes may be undersized, cloudy, or partially formed
- The ice compartment temperature rises while the main freezer remains cold
The rest of the refrigerator (freezer, fridge) continues operating normally because they have their own fan (Er FF covers that).
Diagnosing Er gF
Ice Buildup Around the Fan (40%)
Water from the ice maker mechanism can drip onto the fan blade area and freeze, jamming the blade. This is common after a water line pressure surge or if the ice maker overfills.
Check: Open the ice compartment. Look for visible ice around the fan opening. If present, unplug the fridge, defrost the area with a hair dryer on low, and verify the fan spins freely once ice is cleared.
Fan Motor Failure (35%)
The small fan motor in the ice room is exposed to moisture from the ice-making process. Moisture infiltration into the motor bearings accelerates wear.
Test: Unplug the fridge. Access the ice room fan (usually behind a panel inside the ice compartment). Spin the blade by hand — should rotate freely. If stiff or locked, bearings are seized. Disconnect motor connector and measure winding resistance: expect 20-80 ohms. Infinite = open winding.
Wiring Through Door Hinge (20%)
On models with in-door ice makers, the fan wiring runs through the door hinge area. Like Er CO, these wires flex with every door open/close. After years of use, a wire can break at the flex point.
Board Output (5%)
The board does not send power to the ice room fan. Rare, and usually a secondary symptom of a broader board issue.
Safety First — Know the Risks
Refrigerant (R-134a/R-600a) requires EPA certification to handle. Improper discharge is a federal violation and health hazard. Our techs are licensed and insured — let them handle the risk.

Repair
- Unplug the refrigerator
- Remove the ice bin and any ice compartment panels
- Access the fan motor (behind the compartment rear panel or at the duct opening)
- Disconnect motor connector. Remove mounting screws (typically 2)
- Install new motor (model-specific, $20-40). Reconnect. Verify blade clearance
- Reassemble. Test by running an ice production cycle

Er gF vs. Er FF vs. Er IF
LG uses different codes for different fans:
- Er FF: Main freezer evaporator fan (distributes cold air through freezer and fridge)
- Er gF: Ice room compartment fan (dedicated to ice maker airflow)
- Er IF: Ice maker fan motor (on models with yet another fan in the ice system)
Each is a separate motor with a separate circuit. Er gF specifically means the ice room's circulation fan, not the main cooling fan.
Craft Ice and Er gF
Craft Ice spheres form slowly over 1-2 hours per sphere. The process requires extremely stable sub-zero temperature in the ice compartment. Er gF disrupts this stability immediately — even a few degrees of temperature rise causes the sphere mold to produce misshapen or hollow ice balls. Regular cubes may still form (they are less temperature-sensitive) but Craft Ice stops.
After fixing Er gF, Craft Ice production resumes within 24 hours once the compartment temperature stabilizes.
