The Heil Quaker ICP 1178549 Contactor is a heavy-duty, 2-pole definite purpose contactor engineered for high-demand HVACR applications. Operating with a 24V coil voltage and rated for 40 FLA (Full Load Amps), this component is essential for switching power to the compressor and condenser fan motor in residential and commercial condensing units. As the direct replacement for ICP 1192717, it ensures seamless compatibility with Heil, Tempstar, and Comfortmaker systems. The 50/60Hz frequency rating and robust silver alloy contacts are designed to minimize pitting and carbon buildup, preventing the common "welding" failure seen in sub-standard relays. For field technicians, the universal mounting plate and secure box lug terminals facilitate a fast, reliable installation, maintaining system efficiency and protecting expensive inductive loads from premature failure due to contact chatter or voltage drops.

• Direct OEM Compatibility: Serves as the factory-authorized replacement for part number 1192717, ensuring correct fitment and amperage alignment.
• High Inductive Rating: The 40 Amp FLA rating manages high-torque starts for compressors without excessive heat generation.
• Dual Pole Switching: Provides 2-pole (2P) disconnection for enhanced safety and complete circuit interruption during the off-cycle.
• Climate Resilience: Designed with a specialized shading coil to reduce noise and mechanical vibration in extreme outdoor environments.

Is the 1178549 contactor compatible with other ICP brands?
Yes, this 40 amp 24V contactor is the standard replacement for various International Comfort Products brands, including Arcoaire, KeepRite, and Tempstar, provided the FLA and coil voltage match the original specifications.

Can I use a 30 FLA contactor to replace this unit?
No, replacing a 40 FLA contactor with a lower-rated 30 FLA unit will lead to contact welding and potential compressor damage due to inadequate current-carrying capacity.

What are the symptoms of a failing 24V contactor?
Common indicators include an audible "humming" or "chattering" from the contactor coil, visible pitting on the contact surfaces, or the outdoor fan and compressor failing to engage despite a 24V call from the thermostat.
