Why wine storage is different
A Sub-Zero wine unit has a harder job than any refrigerator in the house. It is holding two zones within a degree of their set points, keeping humidity in the band that protects corks, and damping the vibration that slowly murders a resting bottle. When it drifts, the cost is not spoiled milk, it is a cellar. That is why wine storage calls come straight to our most experienced Sub-Zero hands.
Whether you call it a wine cooler, a wine fridge, or wine storage, the machinery underneath is the same family: a dedicated refrigeration circuit, independent zone controls, and an air system designed to hold conditions steady for years. Onyx technicians work on Sub-Zero exclusively, so a dual zone drifting apart in a Bel Air tasting room or an undercounter unit warming in a Santa Monica kitchen is diagnosed on its own terms, with genuine OEM parts on the van.
Most wine storage repairs are completed in a single visit, with the home protected throughout and the racks and bottles handled only as much as the repair requires, and always with your consent.
The usual suspects
What takes Sub-Zero wine storage off temperature.
Dual zone temperature drift
When the upper and lower zones wander from their set points, the cause sits in a thermistor, a damper, or the zone's own cooling circuit. We measure each zone independently and correct the one that has failed.
The evaporator and airflow
Wine units cool gently, by design, which makes them sensitive to any loss of airflow. An icing evaporator or a slowing fan shows up as a slow, stubborn warming. Traced and restored to specification.
Humidity and condensation faults
Moisture where it should not be, or air too dry to protect corks, points to the unit's climate management. We restore the conditions the storage was engineered to hold.
Door seal and UV protection
A worn gasket on a glass door unit lets warm, humid air work on your collection around the clock. We replace gaskets and confirm the door seats the way the factory intended.
Compressor and sealed system
A weakening compressor surfaces as set points the unit can no longer reach. Sealed system work on wine storage is exacting, and it is work we do with genuine Sub-Zero components.
The worst outcome for a wine unit is a slow failure nobody measures until the collection has spent a season out of band. If your temperatures are drifting, the time to call is now, while the repair is small. One quote, one price, guaranteed repair, with no supplemental estimates, and the 3 Year Onyx Warranty in writing.
The collection, protected
Bottles forgive a warm afternoon, not a warm month
Wine storage fails politely, a degree at a time, and a resting collection will tolerate a brief excursion. What it will not tolerate is weeks of drift. Keep the door closed, note what the display reads, and call us. We answer daily from 7am to 7pm.

Questions, answered
Before you call.
Do you repair both built in and undercounter wine units?
Yes. Full height wine storage columns, dual zone built ins, and undercounter wine drawers across the Sub-Zero line, with genuine OEM parts.
My two zones read different temperatures than I set. Is that a repair?
Usually, yes. Persistent drift in either zone points to a sensor, damper, or cooling circuit fault. It is exactly the failure pattern we are called for most on wine storage, and it is fixable.
Do I need to empty the unit before you arrive?
No. Leave the collection where it is. If the repair requires moving racks or bottles, your technician will handle it with you, and only as much as the work requires.
