Sub-Zero refrigerators are precision-engineered appliances that require specialized knowledge to repair. When your Sub-Zero stops cooling, common causes include dirty condenser coils (Sub-Zero recommends cleaning every 6–12 months), a failed evaporator fan, or a control board issue. Our technicians are experienced with Sub-Zero's dual-refrigeration system and offer same-day service for cooling problems.
Sub-Zero recommends cleaning condenser coils every 6–12 months. Buildup reduces cooling efficiency and can trigger error codes.
Sub-Zero uses separate evaporators for the fridge and freezer. A failed fan in either section causes that compartment to warm up.
Sub-Zero's electronic controls manage the dual-refrigeration system. Board failure causes error codes and temperature irregularities.
Sub-Zero's built-in models rely on tight gasket seals. Worn seals allow warm air infiltration and overwork the system.
Try these before calling for service — they may resolve a simple issue.
Clean the condenser coils — locate behind the kick plate at the bottom front of the unit
Check for error codes on the display (EC 02, EC 25, EC 40, EC 50 are common)
Ensure the unit has adequate ventilation space above and around it
Verify the door seals are clean and making full contact
