Heil Quaker ICP 1176904 Limit Switch

The Heil Quaker ICP 1176904 Limit Switch is a critical high-limit safety component designed for International Comfort Products (ICP) forced-air furnaces. Engineered as a 210F Limit Switch, this genuine OEM part functions as a normally closed thermal disc that opens the electrical circuit when the heat exchanger cabinet exceeds its 210-degree Fahrenheit safety threshold. This furnace high limit switch replacement ensures the system shuts down fuel delivery or ignition to prevent thermal stress or potential equipment damage caused by insufficient airflow or over-firing.

This L210F-40 limit control is built for precise thermal response in tight-tolerance HVACR environments. It is compatible with a wide range of Allied brands including Tempstar, Comfortmaker, Arcoaire, and KeepRite. Specifically, it fits high-efficiency models like the F8MTL, G8MTL, and N8MSL series. For field technicians, the ICP 1176904 offers a direct-drop-in fit with a standard disc mounting configuration, allowing for rapid restoration of the furnace safety string without the need for modifications.

• Precise 210°F Trip Point: Engineered to provide accurate high-limit protection, preventing heat exchanger overheating.
• OEM Compatibility: Authentic ICP 1176904 replacement ensures a proper fit for Heil and Quaker heating systems.
• Enhanced Safety Logic: Reliable thermal disc operation protects the system from airflow obstructions or blower failure.
• Simple Integration: Standard terminal connections and mounting footprint allow for efficient service calls.

What causes a 210F limit switch to trip frequently?
Frequent tripping is usually caused by restricted airflow, such as a dirty air filter, blocked return vents, or a failing blower motor, which prevents heat from being stripped off the heat exchanger.

Is the ICP 1176904 compatible with other brands?
Yes, this switch is a standard ICP replacement part used across several brands under the International Comfort Products umbrella, including Tempstar, Day & Night, and Arcoaire.

Can I use a higher temperature limit switch instead?
No. You should always replace a limit switch with the exact temperature rating specified by the manufacturer to maintain the original safety certifications and protect the heat exchanger.
