Rheem-Ruud 43-25133-32 Run Capacitor

The Rheem-Ruud 43-25133-32 Run Capacitor is a high-performance 70/5 MFD 370V dual-run component designed for demanding HVACR applications. Engineered for Rheem, Ruud, Weather King, and Corsaire systems, this round dual run capacitor provides the precise phase shift required to power both the compressor and the condenser fan motor simultaneously. Built to UL 810 standards and tested for 5,000 AFC (Available Fault Current), it features high-grade dielectric oil and a round metal casing for superior heat dissipation, making it a reliable field-replacement for failed OEM or aftermarket units. With 1/4" quick-connect terminals, it ensures a secure electrical path and rapid installation during service calls. As a critical multi-tap capacitor, it maintains power factor efficiency and protects your compressor motor from excessive amperage draw during start-up and continuous operation cycles.

Key Benefits

• Dual-Run Capability: Integrates 70 microfarad and 5 microfarad capacitance into a single round housing to drive the compressor and fan.
• OEM Compatibility: Direct replacement for Rheem-Ruud 43-25133-32, ensuring seamless fitment in existing mounting brackets.
• Enhanced Durability: Constructed with a high-strength metal canister and non-PCB oil for stable performance in high-ambient temperatures.
• Safety Rated: Certified to UL 810 specifications with an internal pressure sensitive interrupter for fail-safe protection.
• Efficient Performance: Optimizes motor torque and reduces energy consumption by maintaining the correct electrical phase displacement.

Common Questions

Can I use a 440V capacitor to replace this 370V unit?
Yes, technicians often use a 440VAC capacitor as a 370V capacitor replacement because the voltage rating defines the maximum limit; however, you must never install a 370V capacitor into a system requiring 440V.

How do I know if this dual run capacitor has failed?
Look for physical indicators such as a bulged top (mushrooming) or leaking oil. Electrically, a technician should use a multimeter to verify the microfarad (MFD) readings at the 'Herm' and 'Fan' terminals relative to 'C'.

Does this capacitor work with other brands besides Rheem?
While designed as a Rheem Ruud Protech OEM part, this 70+5 uF run capacitor is compatible with any AC or heat pump system requiring these exact electrical specifications and a round form factor.
