York S1-024-25899-000 Run Capacitor

The York S1-024-25899-000 Run Capacitor is a high-spec 12.5 Microfarad 370Vac Oval Run Capacitor designed for continuous duty in residential and light commercial HVACR systems. As a genuine OEM York replacement part, this single run capacitor provides the precise phase shift required to maintain optimal torque and efficiency for condenser fan motors and blower motors. Built with a hermetically sealed aluminum casing, it utilizes a non-PCB biodegradable synthetic oil to dissipate heat effectively during high-load cycles. The 370V oval capacitor configuration ensures a drop-in fit for compact York, Coleman, and Luxaire cabinets where space is limited. Featuring quad-blade quick-connect terminals, it allows for fast, secure wiring. This component meets stringent EIA-456-A industry standards, ensuring stable capacitance ±5% throughout its service life, preventing motor overheating and premature winding failure due to out-of-spec electrical oscillation.

• OEM Compatibility: Exact electrical match for York S1-024-25899-000, eliminating the risks of generic subs.
• High Dielectric Strength: Rated for 370Vac to handle back EMF and voltage spikes in rigorous cooling cycles.
• Optimized Motor Performance: Maintains the 12.5 MFD rating to ensure your motor runs at the designed power factor.
• Durable Construction: Oval run capacitor housing is corrosion-resistant for long-term reliability in outdoor condensers.

Can I use a 440V capacitor if my original was 370V?
Yes, you can upgrade to a higher voltage rating like 440V, but you must never go lower than the 370V requirement stated on the motor nameplate.

How do I know if this 12.5 MFD capacitor is failing?
Common signs include a "bulged" top, oil leaks, or the motor "humming" without starting. Use a multimeter to verify it stays within +/- 5% of its 12.5 Microfarad rating.

Does the shape matter if the specs match?
Electrical specs (MFD and Voltage) are the priority, but the oval profile is critical for fitting into the original mounting bracket of most York air handlers and furnaces.
