this regulator reduces frictional resistance by allowing gas to pass through the conical valve without turbulence

Field Service Efficiency: Features physical dimensions optimized for standard mounting brackets in most condensing units

Built to meet OEM Carrier specifications

it is recommended to mount the switch with the diaphragm in a vertical position to maintain the calibrated set point accuracy across the full 5-30" W

Common indicators include reduced discharge pressure

York S1-031-09157-000 Control Board 30067439-890 this regulator reduces frictional resistanceThe York S1 031 09157 000 Control Board is a critical OEM replacement component engineered for high efficiency management of fan and electric heat sequences. Designed for specific York air handler models like the AVY24B3XH21A, this board acts as the central logic unit, orchestrating the timing for electric heating elements and regulating the circulator blower motor. As a variable speed control board, it ensures precise airflow adjustments and
