Sub-Zero undercounter & drawer refrigerator repair in Sunnyvale

Yes. We service the full compact line — undercounter refrigerators and freezers, refrigerator and freezer drawers, and beverage centers — across Sunnyvale. These units fit a complete cooling system into a low 24-inch cabinet, so they fail in their own pattern: warming, recurring ice, drawer seals and drainage. We diagnose the specific fault with genuine OEM Sub-Zero parts before quoting, and back the labor for 365 days.

On a compact unit, warming usually traces to airflow rather than the compressor. The condenser vents through a slim front grille that loads with dust and pet hair, the evaporator fan can wear, or a thermistor can drift. We clean and test those first, since a choked grille alone can warm a beverage drawer on a hot Sunnyvale afternoon. Sealed-system faults are confirmed with evidence, never assumed on a small unit.

Yes. A drawer that will not close flush is usually a compressed or torn drawer gasket, or runners that have fallen out of alignment so the drawer sits proud. We replace the gasket with a genuine part and true the runners so the drawer seals and glides correctly. Left unaddressed, a poor seal lets in warm, humid air, which then shows up as sweating, frost or a unit that runs constantly.

Because the coil and drain in a compact unit are small, they ice and clog faster than a full column would. Recurring frost points to a blocked drain or a defrost component on that small evaporator, while a poor drawer seal adds humidity that accelerates it. We clear the drain, check the defrost parts, and confirm the seal so the ice does not simply return after the next cycle.

A full column is pulled forward on runners; an undercounter unit is captured beneath a fixed countertop and slides out the front instead. The counter overhang, toe-kick and tight island or bar clearances all decide how it comes out, so we plan the pull in advance and use cabinet-safe protection on the countertop edge and flooring. That care matters most in the island and condo installs common around Sunnyvale.
