York S1-3110-3301 Fan Relay

The York S1-3110-3301 is a heavy-duty 24V DPST 6 terminal fan relay engineered for precise blower motor sequencing in residential furnace and air handler applications. As a direct OEM replacement part for Johnson Controls brands—specifically York, Coleman, and Luxaire—this furnace fan relay provides the switching logic necessary for high-efficiency operation. The double pole single throw configuration allows for simultaneous control of multiple electrical circuits, ensuring the blower motor and auxiliary components engage correctly during calls for heat or cooling. Utilizing high-quality internal windings, the 24V coil minimizes power draw while providing the rapid contact closing required for modern HVAC blower control systems. For technicians, the standardized 6-terminal footprint ensures a seamless drop-in installation into existing mounting brackets. This relay is designed to manage the high inductive loads common in single-phase blower motors, offering a durable solution for field repairs over generic alternatives. Its robust dielectric housing protects against moisture and thermal cycling within the cabinet.

• Direct OEM compatibility with York, Coleman, and Luxaire HVAC systems.
• Efficient 24V low-voltage coil designed for consistent switching under load.
• Robust DPST contact arrangement for improved dual-circuit management.
• Standardized 6-terminal layout simplifies field wiring and circuit identification.
• High-grade internal components engineered for continuous duty in high-cycle environments.

What is the coil voltage for the S1-3110-3301?
This relay operates on a 24VAC control circuit, which is standard for the secondary side of furnace and air handler transformers.

Can this relay replace a SPDT relay?
No, this is a DPST (Double Pole Single Throw) relay. You must verify your specific system wiring diagram to ensure the pole and throw configuration matches the original component requirements.

Why are there 6 terminals on this relay?
The 6 terminals provide connections for the low-voltage coil and the two independent poles, allowing the relay to handle complex switching tasks or secondary auxiliary signals within the air stream.
