Heil Quaker ICP 1185806 Capacitor

As a veteran HVAC technician, keeping the right capacitor on the truck is essential for avoiding callbacks on furnace and air handler calls. The Heil Quaker ICP 1185806 Capacitor is a genuine OEM replacement part specifically engineered for modern International Comfort Products systems. This 5 MFD 250V rectangle capacitor serves as the direct cross for the 1149252, providing identical electrical specs and mounting footprints. Using a genuine 1185806 capacitor ensures the motor start and run cycles remain within factory tolerances, preventing excessive heat buildup and premature motor failure in units like the F9MVE0802120A1 and F9MVE0601714A1. When you are troubleshooting a dead blower or an inducer motor that is humming but not turning, swapping in this 250V AC HVAC capacitor is the standard fix for restoring steady electrical current and peak energy efficiency.

Key Benefits for Technicians:

• Direct Cross Reference: Perfectly replaces legacy part number 1149252 without modifying wiring or brackets.
• OEM Reliability: Built by International Comfort Products (ICP) to match the specific startup torque requirements of Heil and Quaker motors.
• Space-Efficient Design: The rectangular form factor fits into tight control board compartments where standard round silver capacitors won't clear.
• Broad Compatibility: Integrated into a wide range of furnace and air handler models under the Heil, Quaker, Tempstar, and Comfortmaker brands.
• High-Precision Tolerance: Rated at 5 microfarads to maintain the correct phase shift for optimal motor torque and longevity.

Common Questions:

Can I use a higher voltage capacitor if a 250V is not available?
Yes, you can typically use a 370V or 440V capacitor as long as the 5 MFD capacitance is identical, though the physical size may differ. However, using the genuine 1185806 250V capacitor ensures a perfect fit in the original mounting location.

What are the symptoms of a failing 1185806 capacitor?
Usually, you will see a motor that is hot to the touch, humming, or failing to start. In many cases, these plastic-cased rectangle capacitors will show signs of swelling or "bubbling" when they have reached the end of their service life.

Will this work for my furnace model?
This part is the standard spec for popular ICP units including F9MVE0802120A1, F9MVE0601714A1, and F9MVE0801716A1. Always verify the MFD rating on the old part's label before installation.
