Rheem-Ruud 43-25133-07 Run Capacitor

The Rheem-Ruud 43-25133-07 is a mission-critical 50/3 MFD dual run capacitor designed for high-performance service in condenser systems. Engineered to handle 370 VAC, this round metal-can component provides the precise phase-shift needed to energize condenser fan motors and hermetic compressors. As a technical professional, you recognize this 50+3 microfarad configuration as a staple for maintaining Rheem and Ruud equipment efficiency. The 43-25133-07 is the direct replacement for 43-26261-14, offering a seamless drop-in fit with standard 1/4-inch quick-connect terminals clearly labeled for Common, Herm, and Fan leads. Integrated with internal pressure-sensitive interrupters, this dual round run capacitor is built to withstand rigorous 50/60 Hz cycles. Whether you are performing emergency repairs or routine preventative maintenance, using this OEM replacement part ensures you are meeting the exact electrical load requirements of the motor’s start and run windings, preventing premature motor winding failure and ensuring consistent torque delivery under heavy summer thermal loads.

• Precise Capacitance: Features a dual 50/3 microfarad rating (50 MFD for the compressor, 3 MFD for the fan) to ensure balanced motor operation.
• Direct OEM Fit: Specifically replaces legacy part number 43-26261-14 without needing mounting bracket modifications.
• Robust Voltage Rating: Rated for 370Vac applications, providing ample dielectric strength for standard residential and light commercial HVAC units.
• Simplified Wiring: Features standard color-coded terminal clusters (Common, Fan, Herm) for rapid field installation.
• Round Form Factor: Designed to fit standard Rheem-Ruud capacitor straps and perforated mounting brackets securely.

Can I use this to replace a capacitor with a different MFD rating?
No. For the Rheem-Ruud 43-25133-07, the 50/3 MFD rating must match your motor’s requirements exactly; using an incorrect microfarad rating can cause overheating and permanent compressor damage.

Is this capacitor compatible with 440V systems?
While you can often step up in voltage, you should never step down. This unit is rated for 370Vac. If your original part was 440V, do not use this 370V model as it may fail under the higher back EMF of the motor.

How do I identify which terminals are which on this round capacitor?
The terminals on this dual run capacitor are typically marked: "C" for Common, "Herm" for the compressor winding (50 MFD side), and "Fan" for the condenser fan (3 MFD side). Always verify your wiring diagram before energizing.
