Common fault
Why is my Sub-Zero refrigerator not cooling?
Short answer
Check the freezer before anything else. That is a two-minute call to Rancho Santa Fe Sub-Zero Appliance Repair Experts on (858) 923-5340.
Why that is usually the answer
If it is still hard frozen, the compressor has an alibi: this equipment cools the two compartments on separate systems, so a healthy freezer proves the refrigeration itself is working and moves the fault onto the refrigerator circuit. That leaves the fan that moves air across the refrigerator evaporator, a defrost fault that has iced that coil into a block, or the damper that meters cold air into the compartment. In a Rancho Santa Fe kitchen there is a fourth candidate that costs nothing to rule out: a condenser packed solid with dust, which shows up as warmth through a hot afternoon and full recovery overnight.
Where it usually turns out to be
Tell us which pattern you have, because it decides what goes on the van. Warm all day and all night, freezer fine, points at the fan, the defrost circuit or the damper on the refrigerator side. Warm from mid afternoon and normal again by breakfast points at heat rejection, meaning the condenser, the condenser fan or the clearance around the unit. Warm on both sides at once is the one case where the sealed system is genuinely in question, and it is the least common of the three. Any code showing on the display is worth reading out exactly as it appears, along with roughly when the kitchen was fitted, since the year narrows the control architecture and the sensor type we need to carry.
Before you call, there is one check worth doing and it takes a minute. Close the door on a sheet of paper and pull it out. If it slides free without any drag, especially at a top corner, the gasket has stopped sealing there and warm air has been leaking into the compartment continuously. On the integrated columns common in these houses that fault has a specific cause: the custom wood panel is heavy, the door carries that weight on its hinges for years, and the door slowly stops sitting square. The fix is alignment and often a gasket, not refrigeration work, and it is regularly misdiagnosed as a failing unit by someone who never touched the seal.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.

Questions
Answers before you call
Can I call at night, or should it wait until morning?
Call. The scheduling line is answered around the clock and urgent Rancho Santa Fe jobs are dispatched ahead of routine ones. Describe the fault well: that decides whether the right thermistor, fan motor or defrost heater is on the van. A wine cabinet climbing on a Friday night is worth the call. A rattle behind the grille can wait for daylight. Call Rancho Santa Fe Sub-Zero Appliance Repair Experts on (858) 923-5340 and ask.
There are six refrigeration units in this house. Do I have to book six visits?
No. Book the one that failed and list the others when you call: kitchen columns, island drawers, the bar undercounter, the wine cabinet, the back hall freezer, the pool or guest house unit. With the tools already out, each extra unit costs minutes, not a visit, and each gets its condenser cleared, its seals and door alignment checked, its drain proved and its temperature probed.
