York S1-031-03498-001 Demand Defrost Control Board

Description

The York S1-031-03498-001 Demand Defrost Control Board is a genuine OEM replacement component engineered to optimize defrost performance in compatible York heat pump systems. Unlike time-initiated defrost controls, this demand-based board monitors real operating conditions and initiates defrost cycles only when needed — reducing unnecessary energy consumption, minimizing compressor stress, and extending overall system life.

Key Features

• Genuine York OEM demand defrost control board
• Demand-initiated defrost logic for energy-efficient operation
• Reduces unnecessary defrost cycles compared to time-based controls
• Helps protect compressor and refrigerant circuit from frost-related strain
• Direct OEM replacement ensures proper fit and reliable performance
• Designed for use in compatible York heat pump systems

Why Demand Defrost?

Demand defrost technology initiates a defrost cycle based on actual system conditions rather than a fixed time interval. This means the heat pump defrosts only when frost accumulation is detected, preserving heating efficiency, reducing run time in defrost mode, and lowering operating costs over the life of the system.

Application

• Compatible with select York heat pump models requiring demand defrost control
• Intended for qualified HVAC technicians and service professionals
• Always verify compatibility with your specific York unit model before installation
