Copeland 914-0008-49 Start Capacitor

When you're out in the field dealing with a compressor that's struggling to roll over, the Copeland 914-0008-49 Start Capacitor is the industrial-grade solution you need. This 400-480 MFD start capacitor is specifically designed to provide the high-torque electrical surge required to break static friction in HVACR compressors. Rated for 110Vac - 115Vac operation, it features a robust round start capacitor housing that integrates seamlessly into standard motor control boxes. By optimizing the phase shift during the start sequence, this component reduces the duration of high-amp inrush, protecting the windings and ensuring reliable ignition of the refrigeration cycle.

As a veteran tech, you know that Copeland compressor parts are engineered for tight tolerances. This OEM start capacitor is no exception, offering a high microfarad rating (400-480 microfarads) that is essential for heavy-duty reciprocating and scroll compressors used in commercial refrigeration and residential AC units. Its 50/60Hz compatibility and rugged construction make it a staple for any service truck dealing with HVAC motor starting issues or compressor startup failures.

Key Benefits for the Contractor:

• High Torque Output: Delivers a consistent 400-480 MFD discharge to ensure reliable compressor startup under high head pressure.
• Precise Voltage Rating: Optimized for 110V/115V circuits, preventing premature dielectric breakdown often seen with under-rated aftermarket units.
• OEM Compatibility: A genuine Copeland 914-0008-49 part ensures the exact fit and electrical characteristics required by the manufacturer's internal protection logic.
• Reduced Mechanical Stress: Minimizes the internal heat generated during the start-up phase, contributing to the overall longevity of the motor windings.

Common Questions:

Can I use this for a 220V application?
No. This unit is strictly rated for 110-115Vac. Using it on a higher voltage line will result in immediate failure of the capacitor.

What is the difference between this and a run capacitor?
This is a start capacitor designed for short-duration duty cycles to initiate motor rotation. It must be paired with a potential relay or centrifugal switch to be removed from the circuit once the motor reaches speed.

Will this fix a humming compressor?
If the compressor is humming and drawing locked rotor amps (LRA) without turning, a failing 914-0008-49 is often the culprit, provided the compressor hasn't suffered mechanical seizure.
