Rheem-Ruud 43-101665-65 Dual Round Run Capacitor 45/15 MFD 370V

The Rheem-Ruud 43-101665-65 is a genuine OEM dual round run capacitor rated at 45/15 MFD (microfarads) at 370 VAC. Designed for use in residential and commercial HVAC condensing units, this capacitor supports both the compressor motor and the condenser fan motor simultaneously, eliminating the need for two separate capacitors.

Run capacitors are engineered for continuous-duty operation, remaining energized the entire time the system is running. This dual-capacitance design stores and releases electrical energy to maintain smooth motor startup and steady operation throughout each cooling cycle, helping to maximize system efficiency and extend motor life.

Key Specifications:

• Capacitance: 45/15 MFD (microfarads)
• Voltage Rating: 370 VAC
• Configuration: Dual Round
• Application: Compressor motor + condenser fan motor
• OEM Part Number: 43-101665-65
• Also referenced as: 4310166565

This is a direct OEM replacement part sourced from Rheem-Ruud and is intended for installation by a qualified HVAC technician. Replacing a failed or weak capacitor promptly helps prevent motor burnout and unnecessary system downtime.
