Description
The York S1-02551481000 Furnace Wiring Harness is an electrical assembly used to link the control board with key operational components such as the blower motor, ignition system, and sensors. It is installed inside gas furnace units where it routes low-voltage and power wiring to ensure correct signal transmission and the system coordination in commercial heating HVAC systems. This harness supports reliable communication between the internal furnace modules during heating cycles. It plays a vital role in maintaining proper operation of the furnace within systems by preserving consistent electrical connectivity between the control board and connected furnace subsystems.
