Heil Quaker ICP 1186436 Motor

For professional contractors, the Heil Quaker ICP 1186436 serves as the critical OEM replacement motor for restoring high-efficiency airflow in residential furnaces and air handlers. This 3/4HP ECM blower motor operates on a 115/120V, single-phase circuit at 50/60 Hz, delivering a calibrated 1050 RPM to meet precise CFM requirements. Engineered with ECM technology (Electronically Commutated Motor), it provides superior torque and variable speed control compared to standard PSC alternatives. Built on a NEMA 48 frame with a 1/2" diameter single-side flat shaft (3-7/8" length), this unit is a direct drop-in for ICP part number 1185965 and 1184512. The motor features Class B insulation, ball bearing construction for reduced friction, and is designed for continuous air over duty. It utilizes a counter-clockwise rotation (lead end) and supports arm and grommet mounting, ensuring compatibility with Heil, Tempstar, and Comfortmaker systems. Integrating this furnace blower motor ensures the system maintains peak static pressure performance without the need for external capacitors.

• Direct OEM Compatibility: Engineered as the specific 1186436 replacement motor for 1185965, ensuring exact physical and electrical alignment.
• High-Efficiency ECM Tech: Features advanced variable speed motor control to optimize energy consumption and maintain consistent airflow.
• Durable Construction: Rated for Class B insulation (up to 130°C) and equipped with ball bearings for long-term reliability in high-cycle environments.
• Universal Mounting: 48-frame design with arm and grommet mounting points simplifies installation in standard ICP HVAC equipment.
• Precision Shaft Specs: Includes a 1/2" x 3-7/8" flat shaft to ensure a secure, vibration-free fit with existing blower wheels.

Is the 1186436 a direct replacement for the 1185965?
Yes, the 1186436 is the current manufacturer-authorized direct replacement for old part numbers 1185965 and 1184512.

Does this ECM motor require an external run capacitor?
No, because this is an electronically commutated motor, the control logic is handled internally by the motor module, and no external capacitor is required.

What is the rotation direction for this unit?
The rotation is Counter-Clockwise Lead End (CCWLE), which is standard for the majority of ICP furnace blower assemblies.
