York S1-024-35341-000 Relay

The York S1-024-35341-000 Relay is a specialized 3P time delay relay designed for precise cycle control within residential and light commercial HVAC control circuits. This OEM York replacement part functions as a critical anti-short cycle timer, preventing compressor damage by ensuring an appropriate delay between cooling cycles. Engineered to handle inductive loads common in outdoor condensing units, the S1-024-35341-000 stabilizes system pressure differentials before restart. Its reliable solid-state timing mechanism replaces older mechanical delays, offering better resistance to vibration and thermal stress. For technicians performing HVAC troubleshooting, this relay is a standard component for maintaining compressor protection across various Source 1 and Johnson Controls platforms. Integrating this contactor delay ensures the system adheres to strict on-delay timing sequences, optimizing the lifespan of high-value system components by mitigating rapid cycling during thermostat fluctuations or power interruptions.

• System Longevity: Prevents rapid compressor cycling, reducing mechanical wear and electrical stress on the motor windings.
• OEM Compatibility: Precision-fit York HVAC part ensures seamless integration with factory wiring harnesses and mounting footprints.
• Reliable Switching: Built to withstand the high-amperage transients typical of startup cycles in 24V control systems.
• Field Performance: Simplifies diagnostics with standard spade terminal connections for quick installation during service calls.

Common HVAC Technical Questions

How does this relay protect the compressor from short cycling?
The relay introduces a forced delay-on-make or delay-on-break interval, ensuring the refrigerant pressures equalize before the compressor attempts to start against a high head pressure load.

Can this relay be used in non-York equipment?
While designed as a direct York OEM replacement, its electrical specifications for 24V control voltage allow it to serve as a high-quality universal time delay in similar HVACR applications.

What are the symptoms of a failing S1-024-35341-000?
Technicians typically look for a compressor that fails to engage despite a call for cooling or a system that ignores the safety delay, leading to tripped breakers or blown fuses.
