Common fault
Why is my Sub-Zero refrigerator not cooling?
Short answer
If the freezer is still hard and the fresh food side has gone warm, the compressor is not your problem. That is a two-minute call to Del Mar Sub-Zero Appliance Care on (858) 290-7997.
What is actually going on
Each compartment on this equipment has its own compressor and its own evaporator, so a working freezer proves half the machine is healthy. The fault sits on the refrigerator circuit, and there are three usual candidates: the evaporator fan has stopped, the defrost has failed and iced its coil over, or the damper metering air off that compartment's own evaporator is stuck shut. In Del Mar we check the condenser at the same time, because a coil furred with salt and dust produces the same warm-by-afternoon pattern.
What we check, and in what order
The pattern is worth noticing before you call. A unit that runs warm through the afternoon and is back to normal by morning is telling you it cannot reject heat quickly enough during the day. Near the water that is almost always the condenser. Salt in the marine layer settles on the fins, holds moisture, and binds dust and pet hair into a mat that a household vacuum will not lift. A unit that is warm around the clock and never recovering is a different conversation, and that is where the evaporator fan, the defrost circuit and the damper come in.
What happens on arrival, in order. Grille off, condenser inspected, condenser fan turned by hand to feel the bearing. Then a temperature reading taken at the evaporator rather than off the display, because the display reports what the sensor believes and the sensor is one of the things under suspicion. Then the fresh food evaporator itself: is it iced, is its fan turning, does the defrost heater read continuity, is the thermistor within range. Then the damper. By that point the fault has a name, and you get a price before anything comes off the van.
If that matches what yours is doing, say so when you call — it decides which parts come on the van.
