York S1-024-24103-000 Relay

The York S1-024-24103-000 is an OEM 24V SPST Relay designed for precision switching in residential and light commercial HVAC equipment. As a standard single pole single throw relay, this component is frequently used for managing high-current loads like blower motors and condenser fans through low-voltage thermostat circuits. Engineerd by Johnson Controls for York, Luxaire, and Coleman systems, this 24V HVAC relay features a heavy-duty coil rated for 24VAC, ensuring reliable contact closure even during minor voltage fluctuations. When replacing a furnace blower relay, technicians favor this part for its direct-fit compatibility and robust terminal construction, which minimizes resistance and heat buildup. This HVAC control relay is essential for maintaining the sequence of operation in air handlers and furnaces, providing a clear path for line voltage while isolating the sensitive control board from inductive flyback.

• Direct OEM Replacement: Matches exact mounting footprints and terminal layouts for York S1-024-24103-000 specifications.
• Industrial Build Quality: High-grade contact materials prevent pitting and carbon tracking over high-cycle operations.
• Versatile Application: Ideal for furnace fans, AC condenser kits, and general-purpose 24V switching requirements.
• Simplified Diagnotics: Predictable coil resistance and clear terminal labeling streamline troubleshooting in the field.

Is the S1-024-24103-000 a normally open or normally closed relay?
This is an SPST (Single Pole Single Throw) Normally Open (NO) relay, meaning the circuit completes only when the 24V coil is energized.

Can this relay replace a 3-terminal or 4-terminal fan relay?
It depends on the wiring logic. This relay utilizes a two-terminal coil and two terminals for the load. Always verify your schematic to ensure you do not require a double-throw (SPDT) configuration.

What is the coil voltage rating?
This relay is specifically engineered for 24VAC control systems commonly found in North American HVAC equipment.
