LG Refrigerator Ice Buildup
Refrigerator Ice Buildup is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Hard water plus a hot garage
7.2 grains per gallon scales the fill side while ambient heat loads the sealed side; undercounter units in a garage see both at once.
A blocked or frozen water supply line
Shows up as slow or stopped production, and is a plumbing-side issue rather than the ice-making mechanism itself.
A worn ice maker motor or mold assembly
The mechanical components that form and eject cubes wear out gradually.
Local conditions that matter here
Concord averages 88.0°F in July. Oakland, twenty miles west through the Caldecott, averages 71.6°F, and the annual swing out here is 30.4°F against 13.9°F there. A condenser in a garage on this side of the tunnel works in air the bay side never sees, runs long, runs hot and fails early — and the wine room behind that garage wall is doing the same work.
