Ice sheeting on the back wall of the cabinet and the temperature slowly rising. Defrost heater had failed open. He cleared the ice, replaced the heater and the thermal cutout together because they fail as a pair, and cleaned the drain while he was in there.

Wine cooler repair
across the Bay Area
A wine cooler is a machine built to hold one number. When it stops holding it, the wine is what pays. We repair wine coolers and wine refrigerators — free-standing, under-counter, built-in columns, dual-zone, thermoelectric and compressor — and nothing else. Sub-Zero and Viking wine storage, EuroCave, Thermador, Liebherr, Perlick, Marvel, U-Line and seventeen more.

The whole job, in one line
Wine storage runs between 45 and 65 degrees Fahrenheit. 55°F is the long-term storage set point. Below about 45°F corks dry and shrink; above about 65°F the wine ages faster than it should.
01 What comes in
What goes wrong with wine coolers
Six calls out of seven are one of these. Each one has a page that says what the fault actually is, what we check first, and what it usually turns out to be.
01 It is not cooling
The number climbs and stays climbed. Condenser, fan, sensor, seal or charge — in that order, because that is the order they actually fail in.

Read → 03 Fog on the glass, water in the baseA gasket that has taken a set, a sagging hinge, or a door heater circuit that has gone open. All three look identical from the kitchen.

Read → 02 How the machine works
How a cooler holds 55°F — and where it loses it
A compressor wine cooler moves heat out of the cabinet and dumps it into your kitchen through the condenser. That is the whole machine. Everything that goes wrong is a failure somewhere along that path, and the path has an order.
The condenser goes first, because it sits at floor level behind a grille and spends years inhaling dust, pet hair and whatever is on the floor of a kitchen. A matted condenser cannot reject heat, so head pressure rises and the unit loses the bottom of its temperature range — it will hold 60 and never see 55. Then the fans: a condenser fan that has lost its bearings, or an evaporator fan that has stalled, gives you cold metal and warm bottles. Then the sensor, which drifts with age and lets the display report a number nobody can argue with while the wine sits six degrees warmer. Only after all of that does the sealed system come into it.
That order matters because it is also the order of cost. Most wine cooler faults are cheap. The expensive diagnosis is the one that gets reached for first.

04 What happens
What a visit actually looks like
- First — measure
- A calibrated probe goes on the middle shelf and stays there. We read the panel, we read the shelf, we read the discharge air at the grille. Those three numbers rule out most of the possibilities before a panel comes off.
- Then — find it
- Condenser, fans, sensor resistance against its published curve, door seal and hinge, drain. Gauges go on the sealed system only when everything upstream of it has been cleared.
- Then — the number
- You get told what failed, what the part is, what it costs and whether the repair is worth doing on that machine. If it is not, we say so. The $89 service call is waived when you book the repair.
- Parts
- Genuine OEM parts where the manufacturer supports the model, and a specification-matched equivalent where they do not — which we tell you about before we fit it, not after.

06 Straight answers
Questions we get asked
What temperature should a wine cooler hold?
55°F is the long-term storage number and it is where single-zone cabinets should sit. Dual-zone units are usually set around 45–50°F for whites and sparkling in the top or bottom zone and 55–62°F for reds in the other. Below about 45°F corks dry and shrink; above about 65°F wine ages faster than it should.
My cooler says 55 but a thermometer on the shelf says 62. Which is right?
Usually both. The display reports an air sensor in the cold path, not the temperature of your bottles. That gap means either the sensor has drifted or the air is not circulating. Comparing the panel against a calibrated probe on the middle shelf tells us which, and it takes minutes.
Do you repair wine coolers of every brand?
We work on free-standing, under-counter, built-in column, dual-zone, thermoelectric and compressor wine coolers from EuroCave, Vinotemp, U-Line, Marvel, Perlick, Liebherr, Thermador, Zephyr, Danby, NewAir, Allavino, Summit, Avanti, Kalamera, Wine Enthusiast, Haier, Cavavin, Dometic, Silhouette, Sub-Zero and others.
What does the visit cost?
$89 for the service call, and it is waived when you book the repair. You get the diagnosis and the price for the fix before any work starts.
Do you build wine cellars or wine rooms?
No. We repair and service wine coolers and wine refrigerators. Cellar construction, cabinetry and wine-room cooling installs are not what this business does any more.
How far do you travel?
The whole Bay Area — San Francisco, the Peninsula, the South Bay, the East Bay, Marin and up into Napa and Sonoma.

07 Customer notes
What people say
The cooler in our bar area was running hot because it had been built into a cabinet with no ventilation gap at the back. He documented it, cut a rear vent with the cabinetmaker, and the compressor now cycles instead of running continuously. That was the actual fix.
Two coolers at our place in Napa, both running warm. He found one had a genuine fault and the other was simply overloaded with bottles packed against the evaporator plate. He fixed the first and rearranged the second, and only charged for the one that needed work.
