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
A fill line that cannot go under the floor
Cutting the slab risks the heating loop, so the line takes a longer overhead route; more run and more joints means more places to restrict or freeze.
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
The Peninsula holds the densest concentration of Eichlers anywhere — more than 2,700 in Palo Alto, and roughly 650 in the San Mateo Highlands. Radiant heat is cast into the slab, there is no crawlspace and no attic, and the kitchen is usually a post-and-beam bay with glass to the floor. Where a unit sits against that glass, solar gain on a west elevation does work a catalogue figure never accounted for.
