High-Temperature Durability: Constructed with industrial-grade ceramic and heat-resistant alloys to prevent electrical leakage and electrode degradation

intended for indoor applications where protection against falling dirt is sufficient but moisture exposure is not expected

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

Engineered for precise fitment in Protech water heater systems

it ensures stable and accurate fluid regulation

York S1-031-09157-000 Control Board 30067439-890 High-Temperature Durability: Constructed with industrial-gradeThe 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
