Copeland 914-0008-66 Start Capacitor

For service professionals maintaining refrigeration and air conditioning systems, the Copeland 914-0008-66 Start Capacitor is a high-performance OEM component designed to provide the necessary starting torque for single-phase compressor motors. This 108-130 microfarad electrolytic capacitor operates at 220Vac and is engineered to overcome the inertia of locked rotor conditions, ensuring a reliable transition from start-up to run mode. Its robust round design and phenolic case are built for the demanding environments of commercial HVACR applications, where rapid cycling and high thermal loads are standard. This 108-130 MFD capacitor is a specific match for various Copeland compressor parts and cross-references, providing a precise fit and HVAC capacitor replacement that restores efficient motor operation. By briefly increasing the voltage at the motor winding, it minimizes mechanical stress and current draw during the critical initial seconds of operation, preventing tripped breakers and winding overheating.

• Optimized Torque: Delivers precise 108-130 µF capacitance to boost motor starting efficiency and reduce start-up time.
• Industrial Durability: Rated for 220V applications with a heavy-duty round phenolic casing for enhanced electrical insulation and heat resistance.
• Broad Compatibility: Engineered as a direct Copeland 914-0008-66 replacement, fitting a wide array of residential and commercial compressor models.
• Efficient Performance: Helps protect motor windings from excessive heat during the start cycle, supporting long-term system stability.

Common Questions

How do I know if my Copeland start capacitor is failing?
Common signs include a buzzing sound from the compressor, the motor struggling to turn over (locked rotor), or the compressor repeatedly tripping the circuit breaker during startup.

Can I use a higher voltage capacitor as a replacement?
Yes, you can use a capacitor with a higher voltage rating than the original (e.g., 330V replacing 220V) as long as the MFD capacitance range remains exactly 108-130 microfarads to match the motor's design specifications.

Does this start capacitor require a bleed resistor?
Technicians should check the original installation; if a bleed resistor was present to discharge residual voltage, it is best practice to move the resistor to the new unit or install a new one to prevent arcing across relay contacts.
