Ice Maker Runs Constantly is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
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.
Shows up as slow or stopped production, and is a plumbing-side issue rather than the ice-making mechanism itself.
The mechanical components that form and eject cubes wear out gradually.
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.
Based on symptoms like this, these are the components our technicians check first. The exact part depends on your model and what we find during diagnosis.
