Sub-Zero Wine Cooler Repair
Zone drift, condensation and failed lighting on Sub-Zero wine storage and undercounter wine units.
What owners describe when they call
- Upper zone reads 55°F and the lower zone will not come below 60°F
- Condensation running down the inside of the glass door
- Interior LEDs dead on one side or flickering when the door opens
- Unit humming loudly at night in a room next to a bedroom
What the diagnosis includes
Temperatures logged in the cabinet and at the evaporator, the defrost circuit taken through a cycle, both fans and the door seals checked, and gauges on the sealed system when the signs lead there. You come away with the cause and one parts-and-labour figure; the bands below show where that figure is likely to fall.
What it costs
The price list, band by band
The $89 service call pays for the trip out and a complete diagnosis of the unit, and all of it is credited toward the repair once you give the go-ahead.
Each band is what that kind of repair has come to in Sammamish kitchens. Your own unit gets one firm parts-and-labour number once it has been diagnosed, written down before a panel comes off, and that number is the one on the invoice.
- Door gasket or seal replacementA door that no longer seals lets room air in; frost and a long-running compressor follow.
- $300–$630
- Evaporator or condenser fan motorOne fan moves cabinet air over the evaporator, the other moves room air over the condenser.
- $330–$720
- Defrost heater, thermostat or sensorThe parts that clear frost from the evaporator and tell the control how cold it is.
- $300–$690
- Ice maker, water valve or supply lineEverything between the water connection at the back of the unit and the ice maker module.
- $260–$740
- Electronic control boardThe board that runs the compressor, the fans and the defrost cycle from its sensor readings.
- $400–$940
- Compressor or sealed-system repairCompressor, condenser, evaporator, filter-drier and the tubing between them: the refrigerant loop.
- $1,460–$3,380
- For comparison: a new unitA new one on the plateau is a market rate, not a price from this shop: a comparable built-in replacement, before installation and cabinetry work.
- $11,550–$20,400
Three things place a job inside its band: which part your model takes, whether the unit must be rolled out of its opening to reach the fault, and whether a part has to be ordered to your serial number. When a big repair and a new unit start to look alike, the repair-or-replace pages set the two side by side.

Half the interior lighting was dead and the rest flickered every time the door opened. He replaced the LED board and the harness behind the upper trim. The first board was the wrong revision, hence four.
Paloma E.SahaleeMar 2026 Lower zone would not come below sixty whatever I set it to, which the reds survived and the whites did not. The zone damper motor had failed. He replaced it and logged both zones for an hour.
Loretta S.KlahanieOct 2025 The unit shares a wall with our bedroom and had begun humming loudly enough to wake us. Compressor mounts had perished and the fan blade was clipping its shroud. Now you lean in to hear it.
