York S1-024-31994-000 Hardstart Kit

Eliminate compressor startup lag and protect your system during high-load conditions with the York S1-024-31994-000 Hardstart Kit. This genuine OEM HVAC replacement part is engineered for single-phase systems with capacities between 1 to 3 tons, delivering the critical starting torque necessary to overcome initial inertia. In environments with low supply voltage or high head pressure, this 2-wire hard start kit utilizes a high-capacitance start capacitor and potential relay to bridge the gap during the startup cycle, preventing locked rotor conditions and thermal overload trips. Rated for 265 VAC and up to 25 Amps, its compact 2-3/4” x 4” footprint ensures seamless integration into the control box of most standard outdoor units. By significantly reducing inrush current, this kit mitigates stress on motor windings and mechanical components, maintaining optimal performance in residential and commercial air conditioning applications.

• Increased Starting Torque: Provides the electrical boost needed for compressors to start instantly under heavy pressure or low voltage.
• Simplified 2-Wire Installation: Designed for rapid field integration with only two primary connections, reducing diagnostic and labor time.
• Component Protection: Lowers the duration of high-amp draw during startup, preserving the integrity of capacitors and compressor motor windings.
• Optimized Compatibility: Verified for use with 1–3 ton Source 1 and York systems, including model BRCQ0361BB.

Is this kit compatible with 5-ton systems?
No, this specific part number is strictly rated for 1 to 3-ton single-phase units. Using a kit outside its tonnage rating can cause electrical mismatch and component damage.

What is the difference between this and a 5-2-1 kit?
This is an OEM-specified 2-wire configuration, which typically integrates the relay and capacitor into a simpler circuit for faster installation compared to traditional 3-wire 5-2-1 designs.

When should I install a hard start kit?
Technicians should recommend this kit for units experiencing "hard starts," flickering lights during compressor engagement, or systems operating on long line sets and TXV-equipped evaporators.
