Common Sub-Zero Wine Storage Problems

Sub-Zero wine storage systems are reliable, but like all appliances, they can develop issues:

Dual-Zone Temperature Issues

Sub-Zero dual-zone systems maintain different temperatures for red and white wines. When zones don't maintain separate temperatures, it's usually control board, sensor, or dual-compressor issues. We calibrate dual-zone systems to manufacturer specifications.

Sealed Compressor Failure

Sub-Zero uses sealed compressors that require specialized service. Compressor failure symptoms include: no cooling, loud noises, or unit runs constantly. We replace sealed compressors with OEM Sub-Zero compressors and proper refrigerant handling.

Humidity Control Problems

Sub-Zero wine storage maintains optimal humidity (50-70%) to prevent cork drying. Humidity system failures cause condensation issues or dry air. We repair humidity control systems and water reservoirs.

Electronic Control Board Issues

Sub-Zero's electronic controls manage temperature, humidity, and dual-zone operation. Control board failures cause erratic operation, display issues, or complete system failure. We replace control boards with OEM Sub-Zero parts.

Door Seal Problems

Worn door seals allow warm air entry, causing temperature fluctuations and energy waste. Sub-Zero door seals are precision-fit. We replace seals with OEM Sub-Zero gaskets for perfect seal.

Refrigerant Leaks

Sub-Zero systems use specific refrigerants. Leaks cause gradual cooling loss. We locate leaks with electronic detectors and repair with proper Sub-Zero refrigerant recharge.
