LG Refrigerator Repair in Toronto — Ice maker not working

• Er IF (LG also prints it as Er 1F — the '1' vs 'I' is just a 7-segment-display rendering of the same code) is the most common 'dead ice maker' code we see on LG French-door and side-by-side units, and it is the ice-maker-compartment fan motor, not the ice maker module. The DC fan reports RPM/speed feedback to the main board, and when frost jams the blade or the motor opens the board loses that feedback and stops freezing — so the bin goes empty even though the rest of the box is cold. We thaw the iced fan duct first, then if the motor is dead the part is the EAU64824401 fan motor (this is LG's evaporator/compartment DC fan motor, and it supersedes the older EAU61505013, so a parts-counter cross-reference is normal here).
• When the ice maker cycles but never fills, the fault is upstream of the module — the dual-solenoid water inlet valve AJU72992603 (it feeds both the ice maker and the door dispenser off two coils). A coil that reads open on the ohmmeter, or low household pressure below ~20 psi at the valve, starves the fill. The tell is 'no ice AND weak/no dispenser water'; if only the ice side is dead with dispenser water fine, we look at the ice-maker fill circuit instead of condemning the whole valve.
• A genuinely dead ice maker — module cycles on the test button but produces nothing, or won't cycle at all — is the AEQ73110205 ice-maker assembly (the 6-wire LG/Kenmore unit that carries its own mold, ejector motor, heater and thermostat). We confirm by holding the module test button ~3 seconds to force a fill-freeze-harvest cycle before replacing; a unit that won't complete harvest with good water and good airflow is the assembly itself. (Check for the small white 6-wire connector before ordering — LG used several non-interchangeable ice-maker generations.)
• Fill-tube freeze masquerades as a dead ice maker: LG routes the fill tube into the top-rear of the ice compartment, and a freezer set too cold (or a worn door gasket leaking humid air) freezes a plug in that tube. The module keeps cycling but hits ice instead of water, so the bin stays empty. The fix is thawing the fill tube and correcting the cause (gasket / freezer setpoint) — no part needed — and we verify by checking the freezer holds below ~15°F so the module will even attempt a cycle, but the tube is clear.
• On LG Craft Ice models (the LRMVS / LRFVC / SRFVC craft-ice platform) the round-ice side can be dead while standard cube ice still works, or the whole maker can stop: the higher-torque mechanism that twists the frozen sphere free burns out or binds, often with a grind or click on test. LG services this as the Craft Ice maker assembly — on the LRMVS3006S-class units that part is AEQ73449909 (LG's OEM 'Automatic Ice Maker Kit' for the craft-ice platform). Because these craft-ice assemblies are model-specific, we confirm the exact assembly by model number before quoting, and we test-cycle and listen for the strain first.
• A frosted-over ice compartment that keeps re-triggering Er IF after a thaw is an air-seal / defrost problem, not a fan you can keep replacing: a torn door gasket or a defrost-circuit issue lets humid air load the compartment with frost that re-jams the EAU64824401 fan within weeks. We address the moisture source (gasket, defrost heater/sensor) alongside the fan so the same code doesn't come back — replacing the fan alone on a frost-loaded box is a repeat call.
• Don't confuse a dead ice maker with the not-cooling codes on the same platform: Er IF is ice-compartment airflow, but Er FF (freezer fan — on many LG platforms the same EAU64824401 evaporator/compartment DC fan motor is what's behind it) and Er dH (defrost-did-not-complete, MEE62805106 defrost-heater assembly) also choke cold air and can starve the ice maker as a side effect while the real complaint is warming food. If the fresh-food side is also drifting warm we chase the FF/dH path first — fixing those often restores ice without touching the AEQ73110205.

LG ice maker not working in Toronto — the local specifics

• The recurring LG-in-Toronto pattern for a dead ice maker is Er IF / Er 1F traced back to a frosted-over ice-compartment fan rather than a failed ice-maker module — and it keeps coming back when the underlying moisture source (a worn door gasket or an over-cold freezer) isn't corrected with the fan. The second recurring pattern is the fill-side starve: an LG that 'stopped making ice' over winter where the real fault is a frozen fill tube or a low-pressure supply line at the AJU72992603 valve, not the maker itself.
• We carry the common LG ice-maker parts to these Toronto calls: the 6-wire AEQ73110205 ice-maker assembly, the EAU64824401 evaporator/compartment DC fan motor (supersedes EAU61505013), and the dual-solenoid AJU72992603 water inlet valve — plus we arrive ready to thaw a frozen fill tube or frosted fan and check the freezer setpoint and supply-line pressure before fitting any part, so a starve doesn't get misdiagnosed as a dead module. Craft-ice models (e.g. the LRMVS-platform AEQ73449909 assembly) we confirm by model number and order in if needed.
