Heil Quaker ICP 1172090 Run Capacitor

The Heil Quaker ICP 1172090 is a heavy-duty 30/3 microfarad dual run capacitor designed for high-demand HVACR applications. Operating at 370Vac with a 50/60Hz frequency, this round motor run capacitor provides the precise phase shift required to maintain the torque and efficiency of both the compressor and fan motor. Built to withstand rigorous duty cycles, it features a metallized polypropylene film dielectric and is housed in a rugged aluminum casing to ensure superior heat dissipation during continuous operation.

This ICP replacement part is a critical component for restoring the power factor in residential and commercial condensing units. As an industry-standard 30+3 MFD 370V round capacitor, it serves as a direct cross-reference for various brands under the ICP umbrella, including Tempstar, Comfortmaker, and Arcoaire. For technicians performing field service, this unit offers reliable quad-blade quick-connect terminals for simplified wiring and is rated for temperatures up to 70°C (158°F), meeting UL 810 safety standards for pressure-sensitive internal protection.

• Dual Capacitance Design: Supports both the compressor (30 MFD) and the condenser fan motor (3 MFD) from a single footprint.
• OEM Compatibility: Exact drop-in HVAC capacitor replacement for ICP 1172090 and Heil 1186415.
• Enhanced Thermal Stability: Oil-filled, non-PCB construction prevents overheating and extends the service life of internal components.
• Standard Round Form Factor: Fits securely into standard mounting brackets found in most ICP-style furnace and AC cabinets.

Can I use a 440V capacitor to replace this 370V unit?
Yes, while a capacitor must meet the microfarad (MFD) rating exactly, the voltage rating is a "maximum" threshold. A 440Vac unit can safely replace a 370Vac unit, but a 370Vac unit cannot be used in a 440Vac system.

How do I know if this capacitor has failed?
Look for physical signs such as a bulged top (tripped internal protector) or oil leaks. On a multimeter, check for a reading within +/- 5% of the 30/3 MFD rating; readings outside this range indicate the need for replacement.

What does the 'C', 'H', and 'F' on the terminals stand for?
'C' is the Common terminal, 'H' (Hermetic) connects to the compressor, and 'F' (Fan) connects to the condenser fan motor.
