York S1-024-35664-000 Relay

The York S1-024-35664-000 Relay is a heavy-duty 30A HVAC switching relay engineered for reliable performance in residential and commercial climate systems. Formally designated as a 24VDC power relay, this factory-approved OEM York replacement part is critical for managing high-current induction loads, such as blower motors and compressors, in response to low-voltage signals from the control board. Also identified by industry cross-references AZ2280-1A-24D and AZ2280-1A-24DF, this component features SPST-NO (1 Form A) contact configuration and quick-connect terminals for streamlined field installation. Its UL Class F insulation rating ensures thermal stability up to 155°C, making it a robust choice for demanding furnace and air handler applications. For professional contractors, utilizing an American Zettler AZ2280 equivalent maintains system integrity and ensures the precise electromagnetic switching required for efficient sequence of operations in York HVAC systems.

• Direct Cross-Compatibility: Exact technical match for AZ2280-1A-24DF, ensuring drop-in replacement without wiring modifications.
• Industrial-Grade Insulation: Class F insulation provides superior heat resistance in high-cycle environments.
• Professional Connection: Features standard 1/4-inch quick-connect terminals for secure, vibration-resistant electrical bonding.

Common Questions

Can I use an AZ2280-1A-24D to replace the S1-024-35664-000?
Yes, these parts are technically identical. The AZ2280-1A-24D is the manufacturer’s base model used by York for this specific 30A relay assembly.

What is the coil voltage for this relay?
This is a 24VDC coil relay. Ensure your control circuit provides DC voltage, as using an AC signal will cause the contacts to chatter and fail.

Is this part suitable for high-limit switching?
While the 30A rating is robust, always verify your specific York HVAC unit's wiring diagram to ensure the relay matches the application’s inductive load requirements.
