Copeland 914-0008-71 Start Capacitor
When you are out in the field and a compressor is struggling to kick over, the Copeland 914-0008-71 Start Capacitor is the reliable fix for increasing starting torque in high-differential pressure systems. This round start capacitor is specifically engineered for solid-state or potential relay applications, providing a critical capacitance range of 189-227 microfarads. Operating at 250Vac, it delivers the necessary electrical surge to help single-phase HVAC compressor motors overcome the mechanical resistance common in systems using non-bleed TXVs.
Ruggedly constructed for the demands of commercial refrigeration and residential AC service, this component ensures consistent performance during short-cycling or low-ambient conditions. Its black phenolic case and standard terminals make it a seamless replacement for worn-out OEM parts. For a veteran tech, it is a standard truck-stock item for high torque start operations, helping to prevent contactor pitting and motor winding overheating by reducing the duration of the start-up inrush current.
Key Benefits for the Contractor- Precise Capacitance: Rated at 189-227 MFD to meet exact manufacturer specifications for medium to high horsepower compressors.
- Voltage Stability: Built for 220-250V circuits, offering the headroom needed to handle voltage fluctuations during peak demand.
- Universal Compatibility: Standard round form factor fits most existing mounting brackets in Copeland and various third-party condensing units.
- Enhanced Torque: Effectively solves "humming but not starting" issues by providing the phase-shift required for a clean mechanical break-away.
How do I know if this is the right microfarad range for my compressor?
Always verify the MFD rating on the failed capacitor's label. This 189-227 MFD capacitor is typically matched with specific potential relays to ensure it drops out of the circuit within milliseconds after start-up.
Can I use a 250V capacitor to replace a 165V or 220V unit?
Yes, you can always go up in voltage rating, but never down. Using this 250Vac start capacitor in place of a lower voltage unit adds a layer of electrical durability to the repair.
Does this capacitor require a bleed resistor?
While often utilized with a potential relay that handles the discharge, installing a bleed resistor across the terminals can help prevent arcing and extend the life of your relay contacts in frequent-start applications.
