A temperature differential between the inlet and outlet often indicates a restricted core that requires replacement

Using a manual reset switch in its place could interfere with the control board's logic and lead to operational errors or safety risks

York S1-025-52313-000 Transformer 320788-703 A temperature differential between theThe York S1 025 52313 000 is an OEM HVAC control transformer engineered for high demand commercial and residential applications requiring a stable 24V secondary output. This 150VA transformer is designed to handle the increased VA draw of multi stage systems, heavy duty contactors, and advanced control boards that standard 40VA or 75VA units cannot support. Featuring a 208 230V to 24V step down configuration, this component ensures precise voltage
