The specialist difference
A Sub-Zero refrigerator is not an appliance you replace, it is one you maintain, the way a serious car is maintained. The cabinet is built into the home, the compressors are engineered for decades of service, and nearly every fault it can develop has a proper, factory specified repair. Onyx exists for exactly that work: we repair Sub-Zero and Wolf, and nothing else, across Los Angeles every day.
That focus matters because Sub-Zero engineering is genuinely different. Most units run dual refrigeration, separate sealed systems for the refrigerator and freezer compartments, electronically controlled defrost, and a control board that quietly records every fault the machine has seen. A technician who lives in these machines reads that history, tests the right circuit, and arrives with genuine OEM parts on the van, which is why most of our refrigerator repairs are completed in a single visit.
Whether you call it the fridge, the refrigerator, or the columns, and whether it is a 48 inch built in behind cabinet panels in Brentwood or an undercounter drawer unit in a Malibu beach house, the standard is the same: white glove protection for the home, a diagnosis at the source rather than a guess, and a written quote that does not move.
What we repair
The Sub-Zero refrigerator faults we see most.
Not cooling or warming slowly
The classic call. A compartment drifting warm points to the sealed system, a blocked condenser, an iced evaporator, or a failed defrost component. We isolate which, then repair it to factory specification.
Door gaskets and hinges
A tired magnetic gasket lets cold bleed out, frost build up, and the compressor run hard. We replace worn gaskets and correct door alignment so the cabinet seals the way it left the factory.
Ice maker and water faults
No ice, slow ice, or water where it should not be. Inlet valves, fill tubes, and the ice maker assembly itself, diagnosed and repaired with genuine components.
Error codes and service messages
EC 40, EC 50, EC 60, a blinking display, or the Service light. The control board tells a factory trained technician exactly where to look. We read it properly instead of resetting it and hoping.
Compressor and sealed system work
The deepest repair a refrigerator can need, and the one where specialist hands matter most. Compressors, evaporators, and refrigerant circuits restored on the 500, 600, and 700 series and the current builds.
Noise, lights, and controls
Buzzing from a unit built to run silent, a dark interior, an unresponsive panel. Fan motors, LED modules, and control electronics, corrected at the component level.
Every repair follows the same discipline: a factory trained diagnosis at the source, genuine Sub-Zero OEM parts, and one written quote before the work begins. One quote, one price, guaranteed repair, with no supplemental estimates. If the job turns out harder once the panels come off, that cost is ours, not yours.
Same day priority
A warming Sub-Zero is today's problem, not this week's
A fully loaded Sub-Zero holds safe temperatures for hours with the doors closed, and it buys you enough time to do this properly. Call us, keep the doors shut, and a factory trained technician takes it from there. We answer daily from 7am to 7pm, and cooling failures move to the front of the day's schedule.

Questions, answered
Before you call.
Do you repair my Sub-Zero fridge model?
Almost certainly. We service the built in 500, 600, and 700 series, the current classic and designer lines, PRO 48 units, undercounter drawers, and integrated columns across Los Angeles. If you are unsure, call with the model number and we will confirm on the spot.
Is it worth repairing rather than replacing?
In almost every case, yes. A Sub-Zero is engineered to be serviced for decades, replacement means cabinetry work on a built in unit, and a proper repair with genuine parts restores factory performance. We will tell you honestly if a repair does not serve you.
How fast can a technician come out?
