International Comfort Products 100241 24" THERMOCOUPLE

The International Comfort Products 100241 is a 24-inch thermocouple designed for gas furnaces with standing pilot light systems. This essential safety component monitors the pilot flame and controls the gas valve to prevent dangerous gas leaks and ensure safe furnace operation.

How It Works:

The thermocouple sits directly in the pilot flame and generates a small electrical current (typically 20-30 millivolts) when heated. This voltage signal keeps the gas valve energized and open, allowing gas to flow to the burners. If the pilot flame goes out, the thermocouple immediately cools down, the voltage drops to zero, and the gas valve automatically closes to prevent unburned gas from accumulating in the combustion chamber.

Key Features:

• 24-inch length provides versatile reach for various furnace configurations
• Self-powered safety device requiring no external electrical connection
• Durable construction designed to withstand continuous pilot flame exposure
• Precision temperature sensing for reliable flame detection
• Direct replacement part for International Comfort Products gas furnaces
• Compatible with ICP brand families including Heil, Tempstar, Arcoaire, and Comfortmaker

Application:

This thermocouple is specifically designed for residential and light commercial gas furnaces equipped with standing pilot ignition systems. It serves as a critical safety device that prevents gas flow when no flame is present, protecting against potential explosions and carbon monoxide hazards. The 24-inch length makes it suitable for installations where moderate reach is required between the pilot assembly and gas valve connection.

Regular inspection and replacement of the thermocouple helps ensure reliable furnace operation and maintains critical safety protections in gas heating systems.
