What goes wrong with a Sub-Zero wine cooler most often?
Each zone against its own thermistor, not the display is where we start, and it is the answer more often than anything else. The full list of what we are called out for is on this page.
Can you fix a wine cooler in one visit?
Usually. We carry the common wine cooler failures on the van; the damper between zones on a dual-zone cabinet is the one that occasionally needs a part ordered, and we tell you the wait before you commit.
Is the repair guaranteed?
Yes. Repairs are backed by up to a year on parts and labor, and we confirm the exact coverage for your repair before we start.
What parts do you use?
Professional-grade replacement parts selected for your specific appliance and model. The common failures are carried on the van, which is why most calls close in a single visit.
What do you check before quoting anything?
The sequence on this page, in order. On a wine cooler that means humidity, and whether corks are drying at the top before any part is named, because guessing at the expensive component is how one visit becomes two.
Can you repair an out-of-warranty Sub-Zero wine cooler?
Yes — most of what we do is on units past the manufacturer's warranty. If yours is still covered we will say so, because they should carry that cost rather than you.
