This 4 MFD 440V Run Capacitor is a vital electrical component designed to optimize the performance of blower motors and fan assemblies in residential and commercial HVAC systems. Functioning as a continuous power stabilizer, this capacitor ensures that your furnace or air handler motor maintains the necessary torque and electrical phase shift required for efficient operation. If your heating or cooling system is exhibiting signs of a failing motor—such as a humming sound without movement, slow fan speeds, or a motor that fails to start—a replacement run capacitor is often the required solution. Engineered for high-voltage reliability, this part helps extend the lifespan of your blower motor by reducing energy consumption and heat buildup during operation.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
