Sub-Zero Wine Cooler Repair in Del Mar, CA

Two degrees of drift is a fault on wine storage rather than a tolerance, and in most Del Mar houses the bottles are worth considerably more than the cabinet holding them. Take the reading at bottle level before you believe the display, because the sensor reports from where the air moves and the racks can sit several degrees away from it. A dual-zone cabinet with one steady zone and one climbing has already proven its compressor; what has failed is the fan, the damper or the evaporator serving the zone that drifted. Fog on the inside of the glass is a different fault altogether, and it belongs to the door rather than to the refrigeration: the seal, or the anti-condensation heating a glass door carries where it has it.

What this covers in Del Mar

Dual-zone columns, undercounter wine cabinets and the built-in wine storage that sits in a Del Mar bar run or butler's pantry. Temperature drift, humidity, condensation on the glass, control panel faults, noisy fans, and the door seals that turn out to be behind most of it.

• Zone-by-zone temperature taken at the racks, not off the panel
• Evaporator fan, damper and thermistor tested per zone
• Glass door seals, and the anti-condensation heating where a door carries it, the usual cause of interior fogging
• Condenser cleaning, which on a coastal cabinet is not optional
• Control board and display diagnosis
• Shelf rail and hinge adjustment on heavy glass doors

A glass-front cabinet on this coast fights a problem that inland ones do not. It is holding a cool, humid interior while humid outside air presses against the same pane, so the moment the door stops holding that pane above dew point, whether the heating it carries has weakened or the seal has stopped pulling, you get fog on the inside of the door and eventually water running down to the bottom rail and into the frame. Owners almost always read that as a cooling failure. It is not. The refrigeration is working exactly as intended, and the glass has simply dropped below dew point because the part whose job was to keep it above dew point has stopped doing it.
