LG Fridge Error Er IF: Ice Fan Frozen

The Logic Verdict

LG’s support rep ties IF/F1 errors directly to the ice maker fan. When frost packs the duct, the fan stalls and the fridge quits making ice. In the video she disconnects power, opens both doors, and lets the cabinet thaw for eight hours with towels catching the melt water. Once the ice is gone and the fan can spin freely again, the code clears without parts—provided you correct the air leaks that caused the frost in the first place.

What It Means

Er IF / IF E / F1 means the control didn’t detect airflow from the ice-room blower. The fan that pushes freezer air into the door-mounted ice bin is either frozen in place or electrically failed, so the refrigerator halts ice production to protect the motor.

Common Causes

• Frost-packed fan shroud. Warm, moist air from a cracked door gasket or a door left open freezes around the blades.
• Door alignment issues. If the French doors aren’t level, the mullion rail doesn’t seal and frost keeps returning.
• Blocked interior vents. Pizza boxes or bins pushed against the return louvers stop circulation and trap moisture in the ice room.
• Failed fan grille assembly. After repeated freeze-ups the AEB72913944 fan can burn out or the bearings seize.

Step-by-Step Fix

1. Try a soft reset. Unplug the refrigerator (or flip the breaker) for two minutes, then power back up. If Er IF flashes again, continue below.
2. Manually defrost the ice room. Unplug the fridge, remove food and the ice bin, prop every door open, and leave towels down for at least eight hours so the fan cavity can thaw completely.
3. Dry and restart. Wipe away leftover moisture, close the doors, plug the unit back in, and allow 24–48 hours for temps and ice-making to normalize.
4. Eliminate air leaks. Level the cabinet, inspect the mullion gasket for tears, and make sure nothing blocks the vents the video highlights.
5. Replace the ice fan assembly if needed. If the code comes back even with clear ducts and tight gaskets, pull the freezer drawer, remove the ice-room cover, and install a new fan grille/motor kit.
6. Schedule service if the fan never energizes. A damaged main PCB or wiring harness can also trigger IF errors and should be checked by a pro.

Parts & Tools

• LG AEB72913944 ice-room fan grille (replaces seized IF/IFe blower assemblies)
• LG MEGL61906001 French-door gasket (stops the warm-air leak that keeps frosting the fan)
