York S1-024-25075-700 Start Capacitor

When you're dealing with a compressor or blower motor that’s humming but failing to cycle on, the York S1-024-25075-700 Start Capacitor is the field-standard solution for restoring high starting torque. This 161-193 Microfarad 220/250Vac Round Start Capacitor is engineered specifically for single-phase 50/60Hz AC motor starting circuits, providing the necessary phase shift to overcome initial inertia in heavy-duty HVACR applications. Encased in a moisture-resistant phenolic resin housing, this unit is built to withstand high-ambient rooftop temperatures and the heavy vibration common in packaged units and heat pumps. As a genuine OEM replacement part, it ensures precise electrical compatibility with Source 1 equipment, preventing the premature winding failure often seen with generic, off-spec components. The non-polarized electrolytic design and dual blade terminals allow for a standard 3-second motor start interval, optimizing system performance under severe load conditions.

• Enhanced Starting Torque: Provides a temporary electrical boost to facilitate rapid motor acceleration under load.
• Rugged Construction: Housed in a durable, oil-resistant round phenolic case for longevity in demanding mechanical rooms.
• Broad Compatibility: Directly replaces part number 11050 and fits numerous York, Coleman, and Luxaire air handlers and condensers.
• Professional Grade: Rated for 250VAC intermittent duty, ensuring it handles the localized voltage spikes typical during start-up.

• How do I confirm if my current capacitor is failing? If the top of the casing is bulged or if you measure a capacitance reading outside the 161-193 MFD range with your multimeter, the part should be replaced.
• Can I use this for a permanent run application? No, this is an intermittent duty start capacitor. It is designed only to be in the circuit for the first few seconds of operation and must be paired with a potential relay or centrifugal switch.
• Is this rated for 208V systems? Yes, the 250Vac rating allows it to safely operate on 208/230V single-phase equipment common in residential and light commercial settings.
