Description
The York S1-02546776000 Wire Harness is an electrical connection assembly used to link the S22 universal control board with APS and DFS safety components in HVAC systems. It routes low-voltage signals between pressure switches airflow sensors, and control logic ensuring coordinated system response during heating or cooling operation. The harness is commonly used in furnaces, and air-handling equipment where accurate communication between safety circuits and control modules is required. Within the unit, it maintains structured electrical pathways that support operational sequencing, fault detection and shutdown control during abnormal conditions or restricted airflow events.
