Why us
Why Homeowners Choose Us
Wine storage relies on stable temperature, gentle airflow, controlled humidity and a door that protects the collection.
We See This Every Day
Temperature zones, fans, humidity, drainage and door sealing are checked together. We diagnose the cause, not just the symptom.
OEM Parts on the Truck
Fans, sensors, gaskets and control components are matched to the exact wine storage model before replacement.
Written Quote Before We Start
A firm price on site. It does not change once work starts.
Up to 1 Year Warranty
Parts and labor, in writing. Same fault inside that window and we return at no charge.
Built-In and Panel-Ready
Doors and drawers carrying custom millwork come off and go back without marking your cabinetry.

Control Board and Compressor Start Service on a Sub-Zero 427RG
Model: Sub-Zero 427RG
Symptom
The wine cooler says “service,” and the temperature will not come down even though it is switched on.
What we found
A thick layer of dust covered the condenser coil in the lower machinery compartment. This coil releases heat from the cooling system, so blocked fins make it difficult for the cabinet to cool effectively. We also found a problem in the control and compressor starting components. The start relay and capacitor help the compressor begin running, while the control board manages its operation; faults in this circuit can leave the cooler calling for cooling without completing a normal cycle.
Repair
We opened the lower service area and carefully removed dust from the condenser fins and surrounding air passages. The control board, start relay and capacitor were replaced, and their electrical connections were secured before power was restored. We checked compressor startup, fan operation and the temperature response in the wine cabinet. During the same visit, we also cleaned the condenser coil on the Thermador refrigerator to improve its ability to release heat.
Parts and service
Control board; compressor start relay and capacitor; Sub-Zero and Thermador condenser cleaning; cooling operation checks.
Result
The wine cooler started cooling again and the service warning was addressed. Both appliances were checked after the work, and the customer was advised to keep the lower vents clear so heat can escape properly.

Wine Storage Control Board Replacement
Model: 427RG
Symptom
The wine cooler was not holding its temperature reliably, and the controls sometimes failed to respond even after restarting it.
What we found
Power and wiring connections were normal, but the main control board was not switching the cooling circuit reliably. No loose terminals or damaged wiring were found, so the fault was traced to the board rather than the connections.
Repair
The failed control board was replaced, and all wiring plugs were transferred and secured. The cabinet controls were set up again, then the cooler was run through several cooling cycles to check its response.
Parts and service
Main control board; wiring and terminal checks; control setup; cooling-cycle checks.
Result
The wine cooler responded normally to its controls and held the selected temperature again. It completed the final checks without the unexpected shutdowns that had interrupted cooling.

Warm Wine Storage in a Sub-Zero 424G/S
Model: 424G/S
Symptom
The wine cooler was no longer keeping the bottles cold.
What we found
Both display readings were at 77 when the cooler was assessed. Service focused on the inside cooling coil and condenser cleaning. The displayed numbers alone do not establish a refrigerant leak or the final cabinet temperature. The evaporator works inside the refrigerated cabinet, while the condenser releases heat outside it. Attending to both addresses the cooling process at different points. The two displayed values provided a starting observation, not a reason to invent a particular leak location.
Repair
The wine-cooler work covered evaporator-coil service and condenser cleaning. This addressed the coil that cools the cabinet and the area that releases heat outside it. The visit also included refrigerator and freezer gasket replacement on a full-size refrigerator. The evaporator service and condenser cleaning were handled as the wine cooler's own cooling work. The appliance was reassembled for an operating check after those areas were attended to. Both appliances received attention during the same visit.
Parts and service
Wine-cooler evaporator service; condenser cleaning; diagnostic service.
Result
The wine cooler was keeping bottles cold again, and both storage zones were checked after service. The customer could return the wine to its usual storage conditions.

Sub-Zero 427RG Wine Storage Sealed System Service
Model: 427RG
Symptom
The customer called because the wine cooler needed repair.
What we found
The lower front service area was opened to reach the refrigeration system. The work focused on the compressor and filter drier, rather than on shelves or door hardware. Compressor service opens the refrigerant circuit, so the filter drier and preparation steps are part of the same repair. The lower access area provides the connections needed to handle that work while keeping it distinct from a door or cabinet adjustment.
Repair
The service covered compressor and filter-drier replacement, refrigerant removal, a vacuum to clear air and moisture and a refrigerant recharge. These steps form a cooling-system repair rather than routine cabinet cleaning. The replacement components were attended to through the lower service area, followed by preparation of the circuit for its refrigerant charge. Tube and electrical connections needed to be secure before startup, and the service panels were restored once operating checks were complete.
Parts and service
Compressor; filter drier; refrigerant removal, vacuum and recharge; 12-month replacement-service warranty.
Result
The wine cooler was running and cooling normally again. Its operation was checked after the compressor service, and it was ready to return to regular wine storage.
Common faults
What Goes Wrong with Wine Storage
Wine storage relies on stable temperature, gentle airflow, controlled humidity and a door that protects the collection.
Temperature Will Not Hold
Sensors, fans, condenser airflow and the refrigeration system are checked before any part is replaced.
Excess Condensation
Door seals, ambient humidity and drainage can all contribute to moisture inside the cabinet.
One Zone Is Too Warm
A multi-zone cabinet may have a fan, damper or sensor problem limited to one section.
Cabinet Is Noisy
Fan motors, compressor vibration and bottle contact can produce different sounds.
Door Seal Leaks
A damaged gasket or misaligned hinge can admit warm air and raise humidity.
Interior Light Fails
Switches, LED drivers and wiring can fail while cooling remains normal.
Display Shows an Error
The code should be read against the exact model before controls are replaced.
Water Collects Below
A drain blockage or condensation problem can leave moisture at the base.
