York S1-02551470002

Fit and Function

This part functions as a pressure transducer within the York ULTRA-NOX furnace systems. It monitors and regulates vent pressure, providing critical feedback to the control system to ensure proper combustion and efficient operation. The transducer outputs a voltage signal that corresponds to the vent pressure, allowing the furnace to adjust the inducer motor and combustion blower motor accordingly. This ensures consistent results during various operational phases, including pre-purge, flame stabilization, and normal running conditions.
