York S1-024-25035-000 Relay

The York S1-024-25035-000 332V Start Relay is a precision-engineered OEM HVAC replacement part designed to manage the high-torque initial power surge required for compressor activation in York, Coleman, and Luxaire systems. Operating at 332V/60Hz, this potential start relay utilizes a combination of high-grade metal and plastic housing to withstand the thermal stress of industrial heating and cooling cycles. For a technician, identifying a failed compressor start relay is critical when a unit hums but fails to engage; this genuine York part ensures the start winding is energized only during the crucial startup phase before dropping out once the motor achieves running speed. By optimizing HVAC compressor startup, the S1-024-25035-000 prevents excessive heat buildup, protecting the internal windings from premature burnout. Whether you are servicing a commercial rooftop unit or a split-system condenser, utilizing this OEM start relay maintains the electrical integrity of the equipment's start-assist circuit and ensures compatibility with original factory specifications.

• Precise 332V Calibration: Specifically engineered for high-voltage applications to provide the exact voltage boost required for hard-start scenarios.
• OEM Compatibility: Guaranteed fit for York, Coleman, and Luxaire equipment, eliminating the risk of incorrect drop-out voltages associated with universal relays.
• Heavy-Duty Construction: Built with industrial-grade materials to manage the 60Hz frequency and high-amperage surges without contact welding.
• System Protection: Automatically disconnects the start capacitor once the motor reaches 75-80% of rated speed, preventing compressor motor overheating.

How do I verify if the S1-024-25035-000 is the correct relay for my unit?
Match the part number with your original manufacturer’s data plate or technical parts list. This relay is widely used in York packaged units and central air conditioner condensers requiring a 332V rated start relay.

What are the signs that this start relay needs to be replaced?
Look for common symptoms such as a "chattering" sound at startup, the compressor failing to turn over while the fan runs, or an audible click followed by the thermal overload tripping. High resistance across the contacts often indicates it is time for a brand-new York S1-024-25035-000.

Can this relay be used as a substitute for lower voltage relays?
No. It is a technical necessity to match the start relay voltage rating with the compressor's requirements. Using a 332V relay in a system designed for a different voltage can lead to failure of the start winding or improper capacitor disconnection.
