Working notes
What we have learned opening wine coolers, written down. No news, no product launches, no company updates — just the faults, in the order they actually happen.
The notes
Wine cooler not cooling: the five real causes
Why a cooler holds 60 and cannot reach 55, in the order the causes actually occur — condenser, fans, sensor, start components, sealed system — and what each one looks like from the kitchen.
Three ways to build two zones
Damper, solenoid valve or twin circuits. Which architecture your cabinet uses decides how far apart the zones can be set and what a dead zone means.
Twenty degrees below the room
Why a thermoelectric wine cooler stops at 62°F in an 82°F kitchen, why that is not a fault, and what it means for whether repairing one is worth it.
Dew point, gaskets and the heater nobody knows about
Six causes of moisture in a wine cooler and the one-minute test that separates them, including the door frame heater that gets misdiagnosed as a seal fault.
Why 55°F, and why stability beats the average
What happens to wine below 45 and above 65, and why a cabinet swinging between 48 and 64 does more damage than one sitting steadily at 58.
Ten points of failure, photographed
Inside the machine: condenser, compressor bay, thermoelectric stack, damper, gasket, control panel and the grille that decides everything.
Why we do not publish a repair price range
A fan and a sealed-system repair are not the same job, and a range covering both tells you nothing. What the service call buys instead.
Why valley coolers drift every August
A condenser that has been marginal since 2023 is invisible in February. Ambient load, heat rejection and the seasonal pattern that gives it away.
Brand repair notes
One page per manufacturer: what they build, how their machines fail, and what parts availability really looks like.

Model, what the panel says, and what a thermometer on the shelf says. That is usually enough to know what we are walking into.
