Heil Quaker ICP 1185330 Run Capacitor

The Heil Quaker ICP 1185330 Run Capacitor is a high-performance 45/5 MFD 440V dual run capacitor engineered for demanding HVACR applications. As a direct OEM replacement for 1172124, this component is critical for restoring peak efficiency to your condenser fan and compressor circuits. Designed with a round dual run form factor, it features 45+5 microfarad capacitance to handle heavy start-up loads while maintaining stable running currents in PSC motors.

This 440Vac capacitor is built for technicians who prioritize reliability; its metallized polypropylene film construction and hermetically sealed aluminum canister provide superior heat dissipation and environmental protection. Whether you are performing a routine AC capacitor replacement or troubleshooting a non-starting outdoor unit, this dual motor capacitor ensures the precise phase shift required for ICP HVAC equipment. Rated for both 370V and 440V systems, it acts as a robust upgrade for 370V-only components, offering increased dielectric strength and resistance to voltage spikes in the field.

• Dual-Value Precision: Delivers 45 MFD for the compressor and 5 MFD for the fan motor in a single, space-saving round housing.
• OEM Compatibility: Serving as the official 1185330 lead, it ensures perfect fitment and terminal alignment for Heil, Quaker, and ICP units.
• Enhanced Durability: The 440V rating provides a higher safety margin over 370V alternatives, reducing the risk of premature failure during peak summer loads.
• Technical Resilience: Features non-PCB oil and a pressure-sensitive interrupter for safe, long-term operation under continuous duty.

Can I use the 1185330 to replace the 1172124?
Yes, the 1185330 is the designated direct replacement for the older 1172124 part number, meeting or exceeding all original technical specifications.

Will a 440V capacitor work if my old one was 370V?
Absolutely. In HVACR service, you can always go up in voltage rating (e.g., replacing 370V with 440V), as long as the microfarad (MFD) ratings match exactly.

What are the signs this dual run capacitor has failed?
Common indicators include a bulging top cap, the compressor humming but not starting, or the condenser fan motor failing to spin at full RPM.
