Copeland 914-0008-50 Start Capacitor
The Copeland 914-0008-50 Start Capacitor is a high-torque electrical component engineered for single-phase HVACR refrigeration compressors. Featuring a capacitance range of 161-193 Microfarads and a 220Vac rating, this round start capacitor provides the necessary phase shift to overcome high head pressures during initial startup. This is essential for systems utilizing non-bleed thermostatic expansion valves (TXVs) where refrigerant pressures do not equalize during the off-cycle. As a genuine Copeland OEM replacement part, it ensures proper impedance matching with compressor start windings, preventing the excessive amperage draw and overheating that typically leads to premature motor failure.
Constructed in a heavy-duty plastic casing, this Type 1 electrolytic start capacitor is designed to remain in the circuit for a fraction of a second until the potential relay or thermistor disconnects it. It is commonly found in walk-in coolers, reach-in freezers, and industrial condensing units. When performing service, always verify that the associated potential relay is functioning correctly, as a stuck relay contact is the primary cause of capacitor failure. This HVAC start kit component meets standard EIA-463-B requirements for industrial applications.
Key Benefits- Enhanced Starting Torque: Provides the critical current boost needed for single-phase compressors to start under heavy load conditions.
- OEM Compatibility: Precision-rated at 161-193 MFD to match original equipment specifications for Emerson and Copeland systems.
- Protects Motor Windings: Minimizes the duration of locked-rotor amperage, reducing heat stress on the compressor motor.
- Industrial Build: Rated for 220V-250V applications, ensuring reliable performance in demanding refrigeration environments.
- Standardized Terminal Connections: Features quick-connect terminals for rapid installation during field service calls.
How do I know if my Copeland start capacitor is bad?
Technicians should look for physical signs of failure such as a bulged top, leaking dielectric fluid, or a blown pressure relief plug. Electrical testing requires a multimeter with a capacitance (MFD) setting; if the reading falls outside the 161-193 Microfarad range, the part must be replaced.
Can I use a capacitor with a higher voltage rating?
Yes, you can use a capacitor with a higher voltage rating (e.g., 330V) as long as the MFD rating matches exactly. However, you should never use a capacitor with a lower voltage rating than the original 220V specification.
Should I replace the relay when replacing the start capacitor?
It is standard practice for veteran HVACR contractors to test or replace the potential relay when a start capacitor fails. If the relay contacts are welded shut, the new capacitor will stay in the circuit too long and fail almost immediately.
