Luxury built-in appliances like Sub-Zero, Wolf, Thermador, Viking, and Miele use brand-specific parts, often sit inside custom cabinetry, and have longer, more detailed warranties. That affects who should repair them, how long parts take, and what the repair costs.
The upside is that these appliances are built to be repaired. A well-maintained built-in refrigerator or range can last many years longer than a standard model.
Check your warranty first. If it still covers your appliance, book service through the manufacturer so the repair is covered. Out of warranty, you can use any qualified independent technician.
Sub-Zero and Wolf owners can check warranty details, register products, and find service on the Sub-Zero, Wolf and Cove owner resources page. Thermador owners can book warranty service and find troubleshooting help on Thermador's service page.
If your appliance is past its warranty, we can help. Our technicians repair luxury and everyday brands across Mountain View.
| Appliance | Common problems |
|---|---|
| Sub-Zero refrigerator | Warm fresh food section, dirty condenser, fan motors, ice maker faults, door gaskets |
| Wolf range or cooktop | Igniters, spark modules, burner valves, oven temperature sensors |
| Thermador cooktop or oven | Igniters and spark modules, control boards, convection fans |
| Miele dishwasher | Drain pumps, error codes, door latches |
| Viking range | Igniters, oven elements, temperature sensors |
Many of these start with simple maintenance issues. For example, a built-in refrigerator's condenser sits at the top or bottom of the unit and collects dust quickly. Cleaning it once or twice a year helps prevent cooling problems.

Repair is usually the better choice for a built-in luxury appliance. A new built-in refrigerator or range can cost many thousands of dollars and may not fit your existing cabinets, while most repairs cost a small fraction of that.
Our guide on whether to repair or replace an appliance explains the 50% rule and why built-ins are an exception. To see every brand we work on, visit our brands section, or learn more about our refrigerator repair service for Sub-Zero and other built-in models.
If your appliance is still under the manufacturer's warranty, contact the brand first so the repair is covered. Once it is out of warranty, you can choose any qualified technician who works on luxury brands.
Usually, yes. Built-in units are expensive to replace and often fit custom cabinetry. Most repairs, even some sealed system work, cost far less than a new built-in refrigerator.
