What IF
actually means.
LG uses IF, or F1 on some displays, for a problem with the ice maker fan. The usual trigger is frost or ice around that fan, which stops it from turning and leaves the ice compartment too warm to make ice.

What to do when IF shows on the ice makerKind of codeFans and airflow
The fan that moves cold air to the ice maker stopped, slowed or froze in place. A door ice maker depends on that air, carried to the door through a duct, so when the fan quits the ice compartment warms and cubes melt and refreeze into clumps. Ice blocking the blades or the duct is ruled out before a motor is ordered.
Usually leads toDiagnostic visit
A visit that traces the water from the supply valve to the bin and back out through the drain, and names the one part that stopped the ice before anything is ordered.
Shows up asNo Ice Coming From the Ice Maker
The mold sits empty or holds one frozen batch that never drops, the bin stays bare for days, and the dispenser gives water as usual: an ice maker not making ice while the rest of the appliance carries on normally.

Before you book,
in this order.
Each step comes from LG's own guidance for IF on its ice makers. Follow it to the end: the last card says whether this is a visit.
Unplug the unit, empty the ice bin and leave the doors open for at least 8 hours with towels in place, as LG describes.
Dry the inside, plug it back in and allow 24 to 48 hours to return to normal.
Check that the doors close fully and the cabinet is level; book a visit if IF comes back.
What not to do
IF does not concern the main freezer fan, which LG reports as FF. It is also not a water supply code, so a filter change will not clear it.

Fans and airflow on other makes
Door ice maker
The ice maker that feeds the dispenser on the outside of a door: tucked into an insulated box in the left door of a French door model, or at the top of the freezer side of a side-by-side, with a chute and an auger carrying cubes to your glass.
Freezer ice maker
The ice maker that sits inside the freezer compartment itself, a tray that twists or a mold with a heater and an ejector, dropping cubes into a bin or drawer you open by hand, with no dispenser on the door.
