Description
The York S1-03103498001 Control Board manages the defrost cycle by monitoring system conditions and initiating defrost operation when frost buildup is detected on the coil. It processes signals from sensors and control circuits to determine when defrost is required, activating system components to restore proper heat transfer. It ensures timely response based on operating conditions. Positioned within control compartments in HVAC systems such as heat pumps and split units it connects to system wiring for coordinated operation. This component supports efficient defrost control, maintains coil performance.
