York S1-024-25184-000 Start Relay

The York S1-024-25184-000 Start Relay is a critical OEM component engineered for high-torque motor starting in York and Johnson Controls HVAC systems. Operating at 332V and 60Hz, this potential-style relay is designed to manage the duty cycle of start capacitors by effectively removing them from the circuit once the compressor motor reaches approximately 75% of its rated speed. Integrating an authentic HVAC start relay ensures that your compressor windings are protected from prolonged high-amperage draw, which is essential for maintaining system efficiency and preventing motor burnout during hot-start conditions.

For contractors performing field service, the S1-024-25184-000 provides a direct drop-in solution for specific HARB-F030SB series units and other compatible residential and light commercial equipment. This potential relay features precise pick-up and drop-out voltage calibration, ensuring reliable mechanical switching without the chatter often associated with universal aftermarket alternatives. When troubleshooting compressor start issues, verifying the 332V rating is paramount for matching the counter-electromotive force (CEMF) generated by the motor, ensuring the S1-024-25184-000 OEM part operates within the original design parameters of the HVAC system.

• Precise Voltage Calibration: Specifically rated at 332V 60Hz to ensure accurate timing of capacitor cutout across varying load conditions.
• OEM Compatibility: Guaranteed fit and function for York and Johnson Controls equipment, cross-referencing with part number 209A78.
• Heavy-Duty Construction: Built to withstand the high-amperage environment of HVAC compressor start circuits.
• Easy Installation: Standard terminal configuration allows for rapid replacement during service calls, reducing downtime for the end-user.

• How do I know if my York start relay is failing? Common symptoms include the compressor humming without starting, tripped circuit breakers upon startup, or the compressor cycling on the thermal overload protector.
• Can I use a universal start relay instead of the S1-024-25184-000? While some universal relays exist, using the specific York S1-024-25184-000 ensures the pick-up and drop-out voltages match the OEM motor's CEMF perfectly, preventing potential winding damage.
• What residential units use this relay? This part is frequently found in York units, including model HARB-F030SB and similar high-efficiency split system condensers.
