Sub-Zero Ice Maker Slow To Produce Ice
Ice Maker Slow To Produce Ice 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
In an Eichler a new water line cannot go under the floor, because there is no floor to go under — the slab carries the radiant heating loop, and cutting it turns a kitchen job into a heating job. Lines here run overhead or around the perimeter, which is why the same repair takes longer on one street than on the next.
