How LG door ice makers fail
On LG French-door and InstaView refrigerators the ice maker sits in an insulated compartment in the left door, fed by freezer air through a duct in the cabinet wall. A small fan pulls that air through. When warm, moist air leaks into the compartment or duct, it freezes — the fan stalls, the board shows Er IF, and ice production stops. That is why "my LG ice maker keeps freezing up" is the number-one LG refrigerator complaint.
Most likely causes
- Frost in the ice compartment — snow-like frost on the walls, ice chunks in the bucket, Er IF.
- No water — water dispenser also slow or dead, or a frozen fill tube at the back of the ice maker.
- Ice maker off — many LG models have an Ice On/Off button or a switch on the ice maker; the display may show an ice-off icon.
- Jammed bucket — clumped ice stops the auger.
- Ice maker failure — the tray never twists or the motor hums; Er It, Er IS, Er IE codes.
- Water valve — clicks but does not fill, or fills with a trickle.
Safe checks
- Make sure ice making is turned on.
- Replace the water filter if it is over 6 months old (sooner with Las Vegas hard water).
- Remove the bucket, break up clumps, and let it thaw on the counter.
- Run a test cycle: on many LG door ice makers, a small button on the ice maker (visible with the bucket out) starts a harvest-and-fill cycle when held for about 3 seconds.
- If the compartment is full of frost: unplug the refrigerator, open the ice-room door, put towels down and let it thaw 6–8 hours. A hair dryer on low, kept moving and away from plastic, speeds it up.
When to call
- Frost returns within a few weeks after a thaw — something is letting moisture in.
- Er IF or another ice code returns after a reset.
- The ice maker does not move during the test.
- No water from the dispenser either, with a new filter.

LG ice maker questions
Why does my LG ice maker keep freezing up?
Humid air is reaching the ice compartment or its duct and freezing. A worn ice compartment gasket, a failed ice-room fan or a drain or duct problem are typical causes. Melting the ice only helps temporarily.
How long does it take an LG ice maker to make ice after a reset?
About 24 hours for a full bucket. The first harvest usually comes within 2–3 hours after the compartment gets cold.
Why is my LG ice maker making small or hollow cubes?
Low water flow — usually a clogged filter or low household pressure — or a failing water valve.
