York Oval Run Capacitor Motors

Overview

The Source1 2420043700 is a 5 MFD oval run capacitor rated at 370 volts, designed as an official OEM replacement part for York HVAC equipment. Run capacitors are essential components in single-phase HVAC motors, providing the continuous phase shift needed to keep motors running smoothly and efficiently. Without a properly functioning run capacitor, motors in air conditioners, heat pumps, and furnace blowers can draw excessive current, overheat, or fail to start altogether. The Source1 2420043700 is engineered to meet original equipment manufacturer specifications, ensuring a direct fit and reliable performance in compatible York systems. HVAC technicians rely on OEM-grade run capacitors because they eliminate guesswork during service calls. A replacement that matches the original voltage and capacitance rating helps restore equipment to factory performance levels without the risk of premature motor failure caused by mismatched parts. The oval form factor is a common industry-standard shape that fits neatly into the capacitor mounting bracket found in many York condensing units and air handlers. At 5 MFD and 370 volts, this capacitor is sized for smaller single-phase motors such as condenser fan motors commonly found in residential and light commercial HVAC equipment. When diagnosing a unit that short-cycles, runs hot, or hums without starting, testing and replacing the run capacitor is one of the first steps a qualified technician performs.
