This high-performance dual run capacitor is a vital component for restoring the efficiency and reliability of your heating and cooling system. Engineered to support both the compressor and the condenser fan motor, this 55/7.5 MFD capacitor provides the essential electrical boost required to start and maintain motor operation. Rated for both 370V and 440V AC applications, it serves as a versatile replacement part for a wide range of residential and commercial HVAC units, including central air conditioners and heat pumps. If your outdoor AC unit is humming but the fan isn't spinning, or if the system fails to kick on during peak heat, a weakened or failed run capacitor is often the cause. Replacing a worn-out capacitor can prevent motor overheating and help extend the lifespan of your HVAC equipment.
