Common fault
Why is my wine cooler not holding temperature?
Short answer
The number on the front panel is not the number the bottles are living at, so take your own reading down at the racks first. Say so when you call Del Mar Sub-Zero Appliance Care on (858) 290-7997.
What is actually going on
The sensor reports from where the air actually moves, and the racks can sit several degrees away from it, which is how a cabinet shows a steady display while the wine sits warm for a month. On a dual-zone unit, one zone holding while the other climbs is good news: the compressor is proven, and the fault belongs to that zone's own evaporator, fan or damper. If the glass fogs on the inside, that is a separate problem entirely, and it belongs to the door — the seal, or the anti-condensation heating the glass carries — rather than to the refrigeration.
What we check, and in what order
Coastal air makes the condensation version of this fault far more common than it is a few miles inland. The cabinet is holding a cool interior while humid outside air presses on the same sheet of glass, so a door that no longer keeps the pane above dew point, through heating that has weakened or a seal that has stopped pulling square, lets the glass fall below it. First it fogs, then it beads, then water runs down to the bottom rail and sits in the frame. The refrigeration in that scenario is working correctly the whole time, which is why replacing a control board changes nothing.
What we check, in order. A temperature reading at rack height in each zone, top and bottom, with the door shut long enough for the cabinet to settle. Then the fan in the drifting zone, then its damper, then its thermistor against known resistance. Then the condenser, which on a wine cabinet is usually harder to reach and correspondingly more neglected than the one in a refrigerator. Only after all of that does the sealed system come into the conversation, and by then the working zone has usually ruled it out anyway.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
