What goes wrong with it
Symptoms we are called out to on Sub-Zero ice makers
Each one covers the likely causes in the order they are worth checking, and what to do in five minutes before booking anything.
-
No ice, slow ice, cloudy ice Ice maker not working
Production that stopped, or halved over a season. Water supply, the freeze cycle and the condenser are the three places this ends up, and they are easy to tell apart.
- Stopped after a filter change
- Half the ice it used to make
- Cloudy cubes instead of clear
-
Filter, line or drain Ice or water tastes off
Ice that smells of the freezer, water that tastes flat or metallic, or both arriving together after a filter change.
- Started after a filter change
- Ice smells of whatever is in the freezer
- Water tastes flat rather than wrong
What we do on it
Repairs we carry out on Sub-Zero ice makers
Starting figures for this equipment in South Florida. The exact cost is confirmed after an on-site diagnostic — and this is not the whole list of what can go wrong, so call if your problem is not here.
-
from $95 Diagnostic visit
We read the active and stored codes on site, then test the sealed system and the airflow before saying anything about the repair. The fee is credited toward the work when you go ahead.
- Active and stored codes read on site
- Sealed system and airflow tested
- Credited toward the repair
-
from $450 Control board repair
Boards vary sharply by series, and parts for legacy units can take a few days to source. We confirm the board is the problem before ordering one — a code on the display is not proof by itself.
- Board confirmed before it is ordered
- Legacy 600 and 700 Series supported
- Display and touch panel problems
-
Priced after diagnosis Maintenance visit
In this climate condenser cleaning is seasonal rather than annual. A maintenance visit is the cheapest hour you will spend on a built-in unit, and it is how most sealed system failures get avoided.
- Condenser cleaned and airflow checked
- Door seals and drainage inspected
- Stored codes read and cleared

About 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.

Questions about Sub-Zero ice makers
It stopped right after I changed the filter.
That is a phrase we hear weekly. A restricted line or the wrong filter for the model is the first thing to check, and drawing off several liters often clears air in the line.
Why is the ice cloudy instead of clear?
On a clear-ice machine that means the freeze cycle is running differently from how it was designed to — water quality, cycle length or airflow. It usually arrives before production drops.
Production halved rather than stopped. Is that the same problem?
Often, yes, and it is the earlier and cheaper moment to look. A condenser struggling to shed heat makes less ice long before it makes none.
