Heil Quaker ICP 1186414 Run Capacitor

The Heil Quaker ICP 1186414 is a professional-grade 50/5 Microfarad 440Vac Round Dual Run Capacitor engineered for continuous-duty performance in demanding HVACR applications. This OEM replacement capacitor is designed to service both the compressor (50 MFD) and the fan motor (5 ?F) in higher-voltage 440V systems. As a veteran-preferred dual run capacitor, it effectively replaces older or failing units?including the 1172117 and 1050700 part numbers?ensuring your condensing unit or heat pump maintains optimal torque and efficiency during start-up and operation.

Encased in a rugged aluminum round housing, this component is built to withstand the thermal stress of high-ambient outdoor environments. The 440Vac rating provides superior overhead compared to 370V alternatives, offering a more resilient solution against voltage spikes. Standard 1/4-inch terminals are clearly marked for "C" (Common), "H" or "Herm" (Hermetic Compressor), and "F" (Fan) to ensure a precise, efficient field installation for any technician servicing Heil, Tempstar, or KeepRite equipment.

• Dual functionality allows for a single-point replacement of both compressor and fan run capacitors.
• Rated at 440 volts to provide better durability and high-voltage spike protection than lower-rated 370V units.
• Precise 50/5 microfarad capacitance ensures the motor windings operate at the correct phase shift for maximum efficiency.
• Compatible with a wide range of International Comfort Products (ICP) brands, including Arcoaire, Comfortmaker, and Day & Night.
• Round case design fits standard mounting brackets found in most residential condenser cabinets.

Can I use a 440V capacitor if my old one was 370V?
Yes. You can always go up in voltage (e.g., replacing 370V with 440V) to increase reliability, but you must never go down in voltage.

Is the shape of the capacitor important for performance?
Electrically, round and oval capacitors are interchangeable as long as the MFD and Voltage ratings match; however, the round shape is required here to fit the existing factory mounting hardware.

What happens if the capacitance (MFD) does not match?
Using the wrong MFD rating can cause the motor to run hot, draw excessive amperage, and lead to premature motor winding failure. Always match the 50/5 ?F specification exactly.
