Rheem-Ruud 43-25133-31 Run Capacitor

The Rheem-Ruud 43-25133-31 is a high-performance dual run capacitor engineered for demanding HVACR applications requiring a 60/10 MFD capacitance at 370 VAC. Designed with a standard oval oil-filled housing, this component provides the critical phase shift necessary for both the compressor and the condenser fan motor to operate at peak efficiency. As the direct OEM replacement for the 43-26271-39, it ensures precise electrical compatibility and physical fitment in Rheem and Ruud equipment. The 370-volt rating offers sufficient dielectric strength for standard residential and light commercial systems, while the dual-value configuration simplifies field replacements by housing two capacitors in a single unit. For technicians troubleshooting HVAC motor start failures or fluctuating amperage draws, installing an OEM-spec dual oval capacitor is essential for maintaining motor torque and preventing premature winding degradation. This heavy-duty component is built to withstand high operating temperatures, ensuring stable microfarad output throughout the cooling season.

• Direct OEM Compatibility: Specifically engineered as the drop-in replacement for part 43-26271-39, ensuring proper terminal alignment and mounting cabinet fit.
• Dual Section Design: Combines a 60 microfarad compressor lead and a 10 microfarad fan lead in one compact oval run capacitor.
• High Dielectric Strength: Rated for 370Vac operation to handle voltage spikes and provide reliable phase displacement for induction motors.
• Technical Reliability: Constructed to rigorous Rheem-Ruud standards to minimize capacitance drift and heat-related failure in high-ambient environments.

Can I use a 440V capacitor to replace this 370V 43-25133-31?
Yes, a 440-volt capacitor can safely replace a 370-volt unit as long as the 60/10 MFD ratings match exactly. The voltage rating indicates the maximum threshold the capacitor can handle.

What are the symptoms of a failing HVAC dual run capacitor?
Common indicators include a humming compressor that fails to start, the outdoor fan motor not spinning, or the capacitor casing appearing "bulged" or leaked at the top terminals.

Why is the 60/10 MFD rating critical for my system?
Using the incorrect microfarad value can cause the motor to run hot, draw excessive amps, or lose starting torque, eventually leading to permanent motor failure.
