This professional-grade 40/10 MFD dual run capacitor is a critical electrical component for residential and commercial HVAC systems. Designed to support both the compressor and the condenser fan motor, this dual-purpose capacitor provides the necessary phase shift to ensure efficient motor startup and continuous operation. Rated for both 370V and 440V applications, it offers high thermal stability and electrical reliability. If your air conditioning unit or heat pump is humming but not starting, or if the fan is spinning slowly, replacing the capacitor is a common and effective solution. This heavy-duty part is engineered for durability, helping to extend the lifespan of your blower motors and cooling equipment while maintaining optimal energy efficiency.
