Copeland 914-0036-04 Start Capacitor

The Copeland 914-0036-04 is a 145-175 Microfarad 250Vac Round Start Capacitor engineered for high-torque motor legal starts in demanding HVACR environments. Designed as an OEM Copeland replacement part, this component provides the necessary capacitive boost to overcome initial motor inertia, ensuring efficient startup cycles for compatible hermetic compressors and refrigeration motors. With a voltage rating of 250V and a dual-frequency capability of 50/60 Hz, it maintains stable electrical characteristics under fluctuating thermal loads. The round start capacitor configuration allows for a streamlined fit within crowded electrical boxes, making it a reliable choice for field technicians performing preventative maintenance or emergency repairs. Its robust construction is specifically tailored for Copeland compressor start circuits, providing the phase-shift required to optimize motor torque without excessive heat buildup during the start-up phase.

• Precise Capacitance Range: Delivers a consistent 145-175 MFD to meet strict OEM torque specifications.
• High Voltage Threshold: Rated for up to 250VAC to handle transient voltage spikes during motor ignition.
• Universal Compatibility: Works across 50/60 Hz systems, making it suitable for a wide range of domestic and international HVACR applications.
• Rugged Round Housing: Compact design ensures easy installation in standard capacitor boots and mounting brackets.

What happens if the start capacitor capacitance is too low?
If the capacitance falls below the required 145 MFD, the motor may fail to generate enough starting torque, leading to humming, stalled rotors, or tripped circuit breakers.

Can I use this 250V capacitor on a 165V system?
Yes, you can substitute a higher voltage capacitor for a lower voltage one as long as the MFD rating matches, but never use a lower voltage capacitor than the original specification.

How do I know if the 914-0036-04 needs replacement?
Technicians should check for physical swelling, oil leaks, or use a multimeter to verify the microfarad reading is within the 145-175 range.
