York S1-024-19082-019 Sequencer Relay

The York S1-024-19082-019 is a professional-grade 24V heat sequencer relay engineered for precise staging of heating elements in electric furnaces and air handler units. This single-pole single-throw (SPST) component is critical for preventing high-amperage surges by introducing a staggered start-up sequence for blower motors and heating coils. Designed for heavy-duty service, it features a switch-on delay of 30 to 90 seconds and a switch-off delay of 1 to 35 seconds, ensuring optimal thermal management and system efficiency. As a genuine OEM York replacement part, it guarantees fitment and performance in compatible HVAC systems. The rugged, vibration-resistant construction is built to withstand high-cycle commercial and residential applications. With integrated quick-connect terminals, this electric furnace sequencer simplifies field installation and minimizes downtime during service calls. Trust the S1-024-19082-019 sequencer to maintain stable HVAC relay control and protect your equipment from the mechanical stress of simultaneous component activation.
