York S1-3024-3111 Relay

The York S1-3024-3111 Relay is a specialized isolation relay designed for precise load management in HVACR systems. This OEM York replacement part features a 24V coil and is engineered to isolate high-voltage circuits from low-voltage controls, preventing feedback that can damage sensitive control boards. Operating with high-reliability contacts, it is a direct replacement for various Source 1 maintenance applications across York, Luxaire, and Coleman equipment. It excels in switching auxiliary components like blowers, pumps, or humidifiers within a furnace or air handler setup. For contractors performing a furnace relay replacement, the S1-3024-3111 ensures electrical compatibility and maintains the integrity of the original factory wiring schematic. Its compact footprint allows for easy installation in crowded control boxes, providing a robust solution for troubleshooting HVAC electrical intermittent failures and ensuring consistent system sequencing during peak demand cycles.

• Direct OEM Fit: Ensures seamless integration with existing wiring harnesses and mounting configurations.
• Circuit Isolation: Protects low-voltage thermostats and control boards from high-voltage spikes.
• Durable Contact Points: Rated for high-cycle reliability in industrial and residential environments.
• Universal HVAC Application: Compatible with a wide range of York and Source 1 equipment lineages.

Is the S1-3024-3111 compatible with 240V loads?
Yes, while the coil is triggered by 24V, the contacts are designed to handle standard line voltage loads typical of blower motors and auxiliary heaters.

Can this relay replace a standard SPDT general-purpose relay?
If the specifications for coil voltage and contact amperage match, the S1-3024-3111 can often replace standard relays, but it is optimized for York-specific control circuits.

What are the symptoms of a failing isolation relay?
Common signs include a clicking sound without equipment activation, intermittent component operation, or a complete failure of the secondary load to energize when the thermostat calls for service.
