Sub-Zero PRO 48 repair in Sunnyvale

The PRO 48 is a 48-inch pro-style built-in refrigerator-freezer with dual refrigeration, meaning the fridge and freezer run on separate sealed systems. It pairs a high-capacity condenser with an integrated ice and water system. We service its cooling, ice, water, fans, sensors and controls across Sunnyvale using genuine OEM Sub-Zero parts, backed by a 365-day labor warranty.

Usually it is a dust-choked condenser or an airflow or fan fault long before the sealed system is to blame. The large condenser collects lint, so we clean it and test the fans and airflow first, then check sensors and the damper. We only quote the sealed system after factory-spec diagnostics confirm it, so you do not pay for guesswork. See not cooling.

Yes. Most PRO 48 ice and water faults are water-side and very fixable: fill valves, supply lines, fill tubes that freeze, and the ice module itself. We trace the full water path, test the valve, and replace failed parts with genuine OEM Sub-Zero components. For the full breakdown, see ice maker and water line repair.

It depends on the fault. A condenser clean or fan replacement often runs from under $200, while control-board or sealed-system work costs more because of parts and labor time. Every job starts with an $89 service call that is waived when you book the repair, and you get a firm quote before any parts go in. See repair pricing.

Yes. The PRO 48 is a large, heavy flush-set built-in, so careful handling matters. We use a cabinet-safe approach that protects surrounding panels, side fillers and flooring while we pull or service the unit. Most repairs are done in place to limit movement, and we leave your kitchen the way we found it, just with a working refrigerator.
