What goes wrong with it
Symptoms we are called out to on Sub-Zero undercounter & drawers
Each one covers the likely causes in the order they are worth checking, and what to do in five minutes before booking anything.
-
Frost, or not cold enough Freezer not freezing
A freezer running warm, frosting heavily, or holding a temperature that looks right on the display and is not right in the drawer.
- Ice cream soft, everything else fine
- Heavy frost on one shelf
- Display reads correctly, contents say otherwise
-
Inside, or on the floor Water leaking from the unit
Water inside the cabinet, under a drawer, or on the floor in front. Where it comes from decides how urgent it is — and built-in units hide it longer than freestanding ones.
- Water pooling in the bottom of the cabinet
- A wet floor in front of the unit
- Ice in the drain or under a drawer
What we do on it
Repairs we carry out on Sub-Zero undercounter & drawers
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 $1,200 Sealed system repair
Refrigerant circuit work, where the diagnosis matters more than the part. A cabinet that cools unevenly, frosts in one zone or runs warm on one side often points here rather than at the control board.
- Leak detection and refrigerant recovery
- Filter drier and line repairs
- Verified back to set point before we leave
-
from $1,400 Compressor replacement
Major work, and worth a straight conversation first. On a well-kept built-in unit it is usually the right call; when it is not, we will tell you that instead of selling you the job.
- OEM compressor available on order
- Dual-refrigeration units, one side at a time
- Honest replace-or-repair advice
-
from $650 Evaporator replacement
Usually follows a sealed system diagnosis. Heavy frost on one shelf, a zone that will not hold, or a defrost cycle that never quite finishes are the symptoms that lead here.
- Frost build-up on a single zone
- Defrost heater and thermistor checked with it
- Access planned before we arrive
-
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
-
from $280 Condenser fan and coil service
The most common job we see in South Florida. Year-round heat and coastal salt air clog and corrode condensers years ahead of schedule, and a struggling condenser shortens the life of everything behind it.
- Condenser cleaning and coil work
- Fan motors running out of range
- Salt-air corrosion near the water
-
from $220 Door gasket replacement
The least expensive fix for a cabinet that will not hold its temperature. Worth checking before anyone opens the sealed system, because a tired gasket imitates far more expensive problems.
- Doors that no longer seal
- Condensation around the frame
- OEM gaskets on order
-
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 undercounter & drawers
Small units, tight access
Refrigerator drawers and beverage centers are built into islands, bars and cabinetry runs where there is no space behind and often none above. The repair is usually straightforward; reaching it is not. How much of the surrounding cabinetry has to come apart is the biggest single factor in how long the appointment takes.
What tends to go wrong
- A drawer unit running warm, most often a condenser starved of airflow in a tight enclosure
- Control and display problems, sometimes the panel rather than the board
- Drawer seals and runners, which affect temperature as much as they affect the feel
- Units under a bar sink, where a slow leak reaches the compartment before anybody sees it
Clearance is not optional
These units need the ventilation gap the manufacturer specifies at the grille. When a kitchen is refitted around one, that gap is often the first thing lost — and a unit that has run hot for a year usually asks for a condenser service before it asks for anything else.

Before you book
Questions about Sub-Zero undercounter & drawers
Why is a small unit not a small job?
Because reaching it is the work. These are built into islands, bars and cabinetry runs with no space behind and often none above, and how much has to come apart drives the appointment length.
It runs warm in summer and fine in winter.
That usually points at airflow: a condenser starved in a tight enclosure, or a ventilation gap lost when the kitchen was refitted around the unit.
There is water under the drawer.
Worth looking at soon. On a unit under a bar sink, a slow leak reaches the compartment before anybody sees it on the floor.
