Product Details

Description

This premium 55/5 MFD dual run capacitor is a vital component for maintaining the peak performance of your HVAC system. Engineered as a dual-purpose unit, it provides the necessary electrical phase shift to support both the compressor and the fan motor simultaneously. Designed for versatility, this capacitor is rated for both 370VAC and 440VAC applications, ensuring a reliable fit for a wide range of central air conditioning units, heat pumps, and furnace blower motors. Replacing a faulty capacitor can resolve common appliance issues such as motors that hum but won't start, intermittent cooling, or a condenser fan that fails to spin. Constructed with high-grade materials for superior heat dissipation and long-term durability, this run capacitor ensures your heating and cooling equipment operates with maximum energy efficiency and motor torque.
