Refrigeration Repair · Bay Area

What we do

ADRIUM repairs built-in columns, French-door fridges, wine reserves, and undercounter refrigeration across 39 East Bay and Tri-Valley cities, with sealed-system work done in-house under EPA 608 certification and backed by a 2-year warranty. The diagnostic is $75, waived with repair. Refrigeration is our biggest call category, so the truck carries the parts we use every week: evaporator-fan motors for Sub-Zero 700 series, defrost-cycle drain heaters for Bosch 800, water valves and ice-maker assemblies for GE and Samsung, common door gaskets, and a calibrated digital manifold. We diagnose to the actual failure before we order. We do not parts-swap and hope.

Workflow is the same every call. Diagnose. Quote with parts and labor itemized. Order if needed. Install. Bench-test the repair (a temperature pull-down, an icemaker harvest cycle, a sealed-system leak check) before we close out. Most repairs are one visit. Sub-Zero column compressor swaps and Sub-Zero sealed-system leaks are usually two: one to diagnose and order, one to install and test.

We are EPA Section 608 Universal certified for refrigerant work. R134a, R600a, R290, R744. We recover, evacuate, and weigh-in charge with a scale. No guessing.

Inside a built-in sealed-system repair

A sealed-system leak on a built-in fridge is the repair most techs skip, because it takes EPA certification and the right tools to do it correctly. Here is the actual work: pressurize the line set with nitrogen, find the leaks with soap, then deal with the corroded copper that caused them.

Common issues. Typical repair.

Sub-Zero 600 and 700 series, evap fan failure. Compressor runs nonstop, food slowly warms. Usually the evap fan motor. We replace with the OEM motor (the aftermarket ones fail in 18 months) and verify the airflow split between fresh and freezer compartments. Two-hour job.

Bosch 800 Series, rattle plus warming. Defrost drain freezes shut, ice builds on the back panel, the evap fan rubs ice. We thaw the drain, replace the drain heater, replace the fan motor. Done in one visit when we have the model number ahead of time.

Samsung RF four-door, no ice production. Almost always the icemaker assembly itself, not the water valve. Samsung has revised the assembly twice; we install the current revision and tell you whether your serial qualifies for the replacement program. One visit.

Sub-Zero 736TCI dispenser dead. The vintage control board is discontinued from Sub-Zero direct but available rebuilt through authorized refurbishers. We test the harness and the dispenser switch first because both can mimic the board symptom.

LG and Samsung sealed-system failures. Linear-compressor era LG fridges fail at the compressor itself. We look up the serial for the recall settlement before opening the panel. If your unit qualifies, the part is covered. Labor often is not. We tell you up front.

Wine columns drifting. U-Line and Sub-Zero wine reserves: one zone holds setpoint, the other drifts five to eight degrees. Damper-motor failure on the 2218 and 3036 U-Line series. Condenser-fan motor on Sub-Zero 424 and 427. Verifiable over a 24-hour hold.
