Sub-Zero Ice Maker Not Working
Ice Maker Not Working 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
The single most supply-dependent part in the house
At 11 to 26 grains per gallon an ice maker furs up in a season; at 4.5 to 9 the same unit runs clean for years, and which one you have is decided by the well field.
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
This is the local fact that matters most for anything plumbed. Groundwater at 11 to 26 grains per gallon is harder than Las Vegas; the imported blend at 4.5 to 9 is not. Two houses a few streets apart get genuinely different water, so a descaling interval that works at one address is wrong at the other, and a softener sized for a previous house is usually wrong at this one.
