Copeland 914-0006-10 Start Capacitor

The Copeland 914-0006-10 Start Capacitor is a high-duty replacement component specifically engineered to provide the high starting torque necessary for HVAC compressor startup. Rated for 270-324 Microfarad (uF) and 330Vac, this round start capacitor is a standard requirement for many Copeland branded hermetic and semi-hermetic compressors used in commercial refrigeration and residential air conditioning applications. A failing capacitor is a primary cause of motor humming or failure to kick over under load; replacing it with this OEM-spec part ensures the motor windings receive the precise phase shift needed for rapid acceleration. Built to withstand the rigorous duty cycles of industrial equipment, the 914-0006-10 minimizes heat buildup during the start-up phase, protecting the compressor motor from premature wear and high-amp draws that can trip breakers. This component is essential for any technician performing targeted HVAC capacitor replacement to restore system reliability.

Key Benefits for Contractors

• Optimized Starting Torque: Provides a precise 270-324 uF capacitance range to ensure motors overcome head pressure during start-up.
• High Voltage Threshold: The 330V AC rating offers robust electrical headroom to prevent dielectric breakdown during voltage spikes.
• OEM Compatibility: Designed as a direct replacement for Copeland part number 914-0006-10, ensuring exact physical fit and terminal alignment.
• Reduced Motor Stress: Facilitates a quick start, which reduces the duration of high inrush current and keeps the motor windings cool.
• Standardized Form Factor: The round electrolytic design fits standard mounting brackets found in most condensing units.

Common Questions

Can I use this capacitor if my old one is rated for 250V?
Yes. You can always use a capacitor with a higher voltage rating (330V) than the original, provided the capacitance (MFD/uF) matches the motor manufacturer's specifications. Never use a lower voltage rating than the original.

How do I know if the 914-0006-10 is the right fit for my compressor?
Check the data plate on your compressor or the service manual. This 270-324 MFD start capacitor is frequently used on Copeland compressors that require a high-torque start kit, especially in refrigeration and heat pump applications.

Is a start resistor required with this capacitor?
In many high-torque applications, a bleed resistor should be soldered across the terminals to discharge the capacitor when not in use. Always verify the existing wiring configuration before installation.
