Heil Quaker ICP 1187293 Run Capacitor

The Heil Quaker ICP 1187293 Run Capacitor is a precision-engineered 7.5 MFD 370V oval motor run capacitor designed for high-demand HVACR applications. As the certified OEM replacement part for legacy components 100191 and 1170648, this unit ensures your blower motor or fan maintains the correct phase shift for optimal torque and energy efficiency. When diagnosing a 7.5 uF HVAC capacitor failure—often indicated by humming motors, hard starts, or high amperage draws—installing this genuine ICP 1187293 part is the standard for maintaining factory-spec current stability. Its compact oval run capacitor geometry allows for seamless retrofitting in tight control boxes where clearance is limited. Built to withstand the thermal stress of continuous operation, it helps prevent premature winding failure in Heil, Quaker, and Inter City Products (ICP) equipment. Always verify electrical continuity and capacitance readings during service to ensure the system is operating within the specified furnace or AC unit tolerance.

Technical Benefits for Contractors

• Direct OEM Supersession: Precisely replaces 1170648 and 100191, eliminating mounting bracket modifications and wiring guesswork.
• Industrial-Grade Ratings: Rated at 370 Volts and 7.5 microfarads, providing the reliable capacitance needed for efficient motor startup and operation.
• Optimized Form Factor: The standardized oval metal case design ensures heat dissipation and fitment compatibility across diverse condenser and air handler models.
• System Protection: Maintains power factor correction to reduce mechanical wear on motor bearings and windings, extending the service life of ICP HVAC systems.

Common Questions

Can I use a 440V capacitor to replace this 370V unit?
Yes, in technical applications, a 440V run capacitor can safely replace a 370V unit as long as the 7.5 MFD rating is identical. However, you cannot go lower than the original voltage rating.

What are the signs that this 7.5 MFD capacitor needs replacement?
Common indicators include a bulging outer casing, oil leaks (electrolytic fluid), or a motor that requires a manual "push" to start. Using a multimeter to confirm the microfarad reading is outside the +/- 5% or 10% tolerance is the best diagnostic practice.

Is the 1187293 compatible with all Heil systems?
While it is a common ICP replacement part, compatibility depends on the motor's specific requirements. Always cross-reference the Heil Quaker 1187293 part number against your unit's service manual or the existing capacitor's label.
