The electromagnetic potential relay design offers superior reliability over generic alternatives by maintaining precise pick-up and drop-out voltage tolerances

it prevents short-cycling while maintaining tight product temperatures

while the solid copper connections ensure professional-grade brazing

If the combustion gases aren't drafting properly due to a bird's nest in the flue or a failed vent damper

York S1-026-32266-001 Pressure Switch Els PW 17895 The electromagnetic potential relay designThe York S1 026 32266 001 Pressure Switch is an OEM replacement part engineered for precise monitoring of the furnace drain line. Calibrated to trigger at . 65 inch water column (WC), this blocked drain pressure switch is a critical safety component designed to detect restricted condensate flow in natural gas furnaces. By sensing backpressure caused by a clogged trap or blocked PVC drain line, it provides essential protection against heat exchanger
