Copeland 914-0008-63 Start Capacitor

The Copeland 914-0008-63 Start Capacitor is a heavy-duty electrical component designed for high-torque motor starting in HVACR applications. Engineered with a capacitance range of 540-648 MFD and rated for 110/115Vac, this round electrolytic capacitor provides the necessary phase shift to initiate compressor rotation under high head pressure. As the direct replacement for the legacy 014-0008-63 model, it ensures seamless compatibility with Copeland compressor start kits. This AC motor start capacitor features a rugged phenolic resin housing to withstand the thermal stress of frequent cycling, making it a reliable choice for HVAC compressor troubleshooting. Technicians should verify the microfarad rating and voltage requirements to ensure optimal capacitor replacement and motor longevity. By integrating this OEM Copeland part, contractors can maintain system efficiency and restore torque performance in demanding commercial or residential cooling systems.

• High Starting Torque: Provides the 540-648 µF boost essential for starting compressors against high pressure differentials.
• Direct OEM Match: Specifically engineered as the 914-0008-63 replacement to maintain the original manufacturer’s electrical specifications.
• Thermal Stability: Built to handle the rapid discharge cycles required in HVAC startup components without excessive heat buildup.
• Reliable Termination: Equipped with standard quick-connect terminals for fast, secure wiring in the field.

What is the difference between the 014-0008-63 and the 914-0008-63?
The 914-0008-63 is the updated manufacturer part number and serves as a direct functional and physical drop-in replacement for the 014-0008-63.

Can I use this capacitor if my motor requires a lower MFD rating?
No, it is critical to match the capacitance range (540-648 MFD) specified by the compressor manufacturer to prevent winding damage or start relay failure.

How do I know if this start capacitor is failing?
Common indicators include the compressor humming without starting, tripped circuit breakers, or visible bulging and leaking from the capacitor casing.
