# Sub-Zero ice makers

### Slow ice comes before no ice

An ice maker rarely stops outright. Production drops off over weeks — a full bin becomes a half bin, then a third — and by the time it is empty the cause has usually been there a while. Clear-ice machines add their own tell: ice that turns cloudy is a water or freeze-cycle problem, not a cosmetic one.

### Common causes

- Water supply: a filter past its life, a restricted line, or a valve that no longer opens fully
- Drain and pump problems on units sitting below the drain line
- A condenser that cannot shed heat, so the freeze cycle never completes
- Leaks that show up as a damp cabinet floor rather than as a puddle

### Outdoor units take it worst

An ice maker built into an outdoor kitchen works against ambient heat all summer and salt air all year. Those are the units we are called out to most after a storm season, and the ones where seasonal condenser cleaning genuinely prevents the expensive repair.
