Check for 24V at the bottom heater terminals (usually labeled H1/H2)

ensuring the correct millivolt output and terminal fit for HVAC gas valves

Durable SPST Construction: Reliable single-pole design ensures a clean break in the 24V or 120V control loop when thermal limits are exceeded

minimizing pressure drop across the loop

York S1-025-26312-700 Transformer Refrigerant drawing only 1The York S1 025 26312 700 is an industrial grade 500VA control power transformer designed for multi tap primary configurations. Engineered for resilience in commercial HVACR environments, this unit handles primary voltages of 380V, 400V, and 416V, stepping them down to 115V or 230V secondary outputs. As a genuine York replacement part, it ensures precise voltage regulation and electromagnetic compatibility for sophisticated control circuits. The Step
