Why premium appliances need a different approach
A Sub-Zero refrigerator's dual-compressor sealed system, a Wolf range's restaurant-style burner valves, a Viking's professional-grade cooking architecture — these aren't scaled-up versions of a mainstream appliance, they're built to a different spec with different failure points. Diagnosing them the same way you'd diagnose a standard-brand unit is how a repair visit turns into a return visit. We test the actual component that's specific to the brand and model before recommending a part.
