Common fault
Why is my Sub-Zero refrigerator not cooling?
Short answer
Start with the freezer. If it is still hard while the fresh food side has climbed, the costly answer is off the table: the compartments run on separate circuits, and a cold freezer proves one healthy. Say so when you call Poway Sub-Zero Repair Experts on (858) 630-4145.
Why we start there
What is left is the fresh food evaporator, its fan, its defrost, or a fouled condenser.
What happens next
The time of day pattern gets left out of most phone calls, because saying it out loud makes the appliance sound healthy. It is not. If the unit holds overnight and through the morning and only drifts warm from early afternoon, that is usually not a failed component at all, it is a cooling system with nothing in reserve once the room warms up. A condenser carrying a season of decomposed granite dust and brush pollen still has enough capacity at eight in the morning and has spent all of it by four. Same appliance, same fault, two completely different sets of readings depending on what time somebody happens to be standing in front of it. Tell us the pattern on the phone and it changes the first thing we open.
If the unit in question is in the garage, say so when you call, because both of the likely faults are ones the kitchen never sees. In summer the ambient out there is far above what the cabinet was rated for and the condenser never gets a recovery period, so it runs continuously and still loses ground. In winter the opposite: on a combination refrigerator-freezer the thermostat senses the fresh food compartment, and if the garage itself is cold enough that compartment stays in range without the compressor ever running. The refrigerator reads perfect, the freezer thaws overnight, and nothing at all is broken. That fault is not fixed with parts, and we would rather tell you that on the phone than after somebody has replaced a control board.
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
How soon can somebody come out, and do you really answer at night?
The line is answered at any hour, seven days a week, and there are same-day slots most days. What decides one visit or two is usually not the diary but whether the right part is already on the van — which is why we ask what the freezer is doing before anything else. Call Poway Sub-Zero Repair Experts on (858) 630-4145 and ask.
Does a built-in have to come out of the cabinetry to be worked on?
Almost never. It is built to be serviced in place: the condenser is reached through its grille — behind the lower kickplate on columns and undercounter units, above the doors on older combination built-ins — and the sealed systems open from the front. Pulling one out risks cabinetry and a custom panel. Say so when you call Poway Sub-Zero Repair Experts on (858) 630-4145.
