Sub-Zero Ice Maker Not Making Ice
Ice Maker Not Making 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 sealed system with no thermal headroom
Production falls off here because the system is already working at the top of its range, not because the module has failed.
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.
