From our technicians’ notes · October 2024 to October 2026
Warm, wet, iced up, or after a fire.
Wine coolers come to us with one of a handful of complaints. Here are six, grouped by what the owner noticed first. For each, you get the town, the technician’s findings and what it cost. Four of the six ended without a repair, and we’ve kept those in.
Not coolingTwo units, both in Lake Sherwood
THERMADOR T24IW905SP · R600a 1.45 oz (41 g)
A new compressor, and then a leaking evaporator
December 2025 to January 2026 · Lake Sherwood, by Westlake Village · built-in wine column
On December 1 the technician found the column was not cooling at all, because the compressor had failed. The fix was a sealed-system job: a new compressor assembly and filter drier, a nitrogen purge, welded connections tested for leaks under pressure, then evacuation and a recharge. That visit closed on December 4 at about $1,885.
The compressor label photographed on December 1: Embraco FMXY9C, with a flammable-refrigerant warning.December 26, gauges set to R600: the suction side pulled into a vacuum at −13.9 inHg while the discharge side read 73.8 psig. A reading taken at 10:32 had the suction side at 0.0 psig.January 14: foam insulation cut back inside the cabinet to get at the evaporator tubing.
It didn’t stay fixed. The column cooled for a while and then stopped again, and the follow-up note blames a refrigerant leak in the evaporator. The gauge readings in late December show the suction side pulled into a vacuum. The evaporator was replaced in January, and that visit closed on January 14, 2026 at about $1,110.
Two visits, just under $3,000 together
SUB-ZERO WINE STORAGE · DISPLAY: Error! 40209
The sensors were replaced, and the error came back
July to August 2025 · Lake Sherwood, by Westlake Village · Sub-Zero wine unit
This one was booked in July 2025 as a recall: the Sub-Zero was showing the same error again. The technician’s note ties the error to the temperature sensors. Those sensors had been replaced and the problem hadn’t gone away. The unit also couldn’t hold its temperature, and that moved the diagnosis to the sealed system.
August 6, 2025: the display reads Error! 40209, with bottles in the racks below.
The estimate covered both evaporators, the compressor, the filter drier and the 3-way valve, plus a nitrogen purge, evacuation and recharge. The compressor and the wine evaporator were priced by Sub-Zero part number (7009447 and 7031656). The job was closed without that work being done.
Ended without the sealed-system repair
Water in the cabinetSame complaint, two different causes
SUB-ZERO 430G/S 2 · NOV 2005 · R134a 4.5 oz
A 2005 Sub-Zero with a blocked drain, not a refrigerant leak
July 2026 · Hollywood Hills, 90069 · built-in wine storage
Booked on the evening of July 16 as a leaking wine cooler that had to be done by noon the next day. The technician found the evaporator drain line blocked and the drain tube damaged, so water was backing up and leaking out. The line was opened with steam pressure and the damaged tube replaced. The job was closed at 11:38 a.m. on July 17. It was invoiced at about $545 for the service call, the drain clearing and the tube.
Booked online as leaking fluid from the bottom. At the July 14 visit the technician found a refrigerant leak. The compressor and evaporator assemblies it needed couldn’t be sourced.
The Vinotemp, a tall glass-door unit, among boxes in a garage.Emptied for the diagnosis: frost patches on the evaporator plate, water on the cabinet floor.
What we offered instead was a stopgap. We would replace the filter drier, recover the refrigerant that was left, purge and evacuate the system, then recharge it by weight on a calibrated scale to the amount on the label. The note says plainly that the leak couldn’t be fully corrected without the missing parts, so that repair would carry no warranty and no promise of how long it would last. It wasn’t done.

Ice building upA two-zone freestanding cooler
WINE ENTHUSIAST ITEM 288 03 32 03 · R600a 21 g
Ice, and a lower zone that wasn’t getting cold
October 1, 2026 · Van Nuys · dual-zone wine cooler
Booked as ice building up. The technician found that the lower evaporator wasn’t getting cold and checked the solenoid valve. It wasn’t opening to let refrigerant through to the lower evaporator, which left a restriction in the system. In this cooler each zone has its own evaporator plate on the back wall, so one stuck valve can leave one zone warm while the other works.

Ended at the $85 diagnostic, no repair recorded
Several units at onceAn inspection with written findings
The technician inspected five units: four Avanti WCR683DZD-1 and one Allavino. Two of the Avantis had defrost-system faults, and one of those two was also leaking refrigerant. Another Avanti was running normally at the time. The Allavino wasn’t running at all, because its compressor relay had failed.

The probable cause in the note is a recent fire, with soot getting into components such as the evaporator and the compressor. The note also warns that the unstable temperatures may have affected the wine, and could encourage mold inside the cabinets.

Sound like yours?
Tell us the brand, whether it’s built in, and what you’re seeing.
Look for a sticker inside the door or on the back: it lists the model and the refrigerant. Of the four below, the two older units run on R134a. The newer Thermador column and the Wine Enthusiast run on R600a, which is isobutane, and the charge is small: 41 grams in the column, 21 in the Wine Enthusiast. The 2005 Sub-Zero holds 4.5 oz of R134a, about 128 grams.
That is why the Embraco compressor in the Thermador carries a flammable-refrigerant warning. It is also why the Vinotemp stopgap was written as a recharge by weight, to the label amount. The Sub-Zero estimate above was built on part numbers.

Compared with the rest of our work
Where wine cooler calls part ways.
They come from a different part of the map.
About half of our wine cooler calls come from seven areas: Pacific Palisades, Brentwood, West Hollywood, Malibu, Encino, Calabasas and Westlake Village. Across all our calls, those seven account for roughly one in ten.
Our wine cooler visits stop at the $85 diagnostic noticeably more often than our visits overall. Sometimes the part can’t be found, sometimes the repair isn’t worth it on that unit, and sometimes the problem isn’t in the cooler at all.
Four of the six visits above ended without a repair.
Mostly the sealed system. Not always.
In five of the six stories above, the notes record a sealed-system fault: a compressor, an evaporator, a refrigerant leak or a valve. The Hollywood Hills drain was the odd one out.
Another exception was a built-in wine refrigerator in Chatsworth that stopped cooling in October 2024. Its control board and control panel were both dead. The manufacturer had both on back order until mid-November; we closed that ticket on November 25, 2024, at about $535.
