Sub-Zero Refrigerator repair and service in New York

This is the classic sign of a Dual Refrigeration system issue. Unlike standard fridges that share air, your Sub-Zero has a dedicated compressor and evaporator for the fresh food section. It likely indicates a slow Freon leak in the fridge loop or a failure of the fridge-side evaporator fan. Since the systems are independent, your frozen food is safe while we repair the fridge section.

This light is a vital warning. Sub-Zero units breathe through the top grille. If the condenser is clogged with dust or pet hair, the compressors overheat and shut down to protect themselves. We perform a professional deep clean of the condenser coils to restore proper airflow and clear the error codes, extending the life of your compressors.

Sub-Zero doors rely on a vacuum seal to keep food fresh. If the door drifts open or condensation forms, the magnetic gasket may be torn or the door hinges may have sagged due to the heavy weight of the custom panels. We can replace the gaskets and re-align the cam-lift hinges to restore that signature airtight closure.

This indicates that the antimicrobial air purification cartridge needs replacing. Sub-Zero uses NASA-inspired technology to scrub ethylene gas and odors, keeping food fresh longer. The cartridge lasts about one year. We carry authentic replacement cartridges and can install them for you during any maintenance visit.

This is a common issue caused by a blockage in the refrigerator’s drain trough. Because the fridge section maintains high humidity, condensation forms on the back wall. If the drain hole is clogged with debris, water overflows onto the floor of the compartment. We use high-pressure steam to clear the blockage and sanitize the drain line.
