Rheem-Ruud 43-25134-03 Run Capacitor

The Rheem-Ruud 43-25134-03 Run Capacitor is a high-performance electrical component engineered for precise capacitance in HVACR systems. Rated at 7.5 MFD (Microfarads) and 370 VAC, this oval run capacitor ensures stable motor torque and efficient current flow to the compressor or fan motor. Designed as a direct replacement for 43-20847-10, it maintains power factor correction and reduces heat buildup, extending the service life of induction motors. This OEM Rheem replacement part is built with a rugged aluminum casing to withstand high ambient temperatures and pressure spikes common in residential and light commercial cooling equipment. The non-PCB oil-filled design provides excellent heat dissipation and self-healing properties, ensuring reliable operation under heavy cycling. Pro-tip for technicians: always verify the microfarad rating and physical dimensions before installation, as the terminal configuration is optimized for standard 1/4-inch quick-connect leads.

• Precise 7.5 MFD Rating: Ensures optimal motor starting torque and running efficiency.
• 370V AC Compatibility: Built for standard HVAC electrical circuits and condenser fan motors.
• OEM Compatibility: Replaces 43-20847-10 seamlessly without modification to the mounting bracket.
• Oval Case Design: Designed for compact control boxes where space is a constraint.
• Thermal Stability: Engineered to operate reliably in high-temperature environments.

Commonly Asked Questions

Can I use a 440V capacitor to replace a 370V capacitor?
Yes, a 440V run capacitor can safely replace a 370V capacitor as long as the 7.5 MFD rating remains the same. However, you cannot go lower than the original voltage rating.

What are the symptoms of a failing 7.5 MFD run capacitor?
Common signs include a humming fan motor that refuses to start, high amperage draws, or visible bulging and leaking from the capacitor casing.

Is the 43-25134-03 compatible with other brands?
While this is a Rheem-Ruud specified part, it is compatible with any HVAC system requiring a 7.5 microfarad 370V oval capacitor.
