Heil Quaker ICP 100241 Thermocouple

When the pilot light won't stay lit on a Heil Quaker or ICP furnace, the ICP 100241 Thermocouple is typically the first component we verify. This 24-inch OEM replacement part is engineered for high-accuracy millivolt signal generation, ensuring the gas valve remains energized only when a consistent pilot flame is detected. Designed specifically for International Comfort Products equipment, this 24-inch thermocouple features a robust copper lead and a high-nickel alloy tip to withstand the constant thermal stress found in residential heating systems.

Installation is straightforward for any contractor familiar with pilot burner assemblies; the threaded nut ensures a secure fit into the thermopile bracket, preventing signal drift or "nuisance" shutdowns. Because it replaces legacy part numbers including 1147788, Q340A1074, and 503344, it is a versatile stocked item for service trucks. Maintaining a reliable flame sensor signal is critical for preventing unburned gas buildup and ensuring the safety of the furnace's ignition system. Rely on this genuine ICP 100241 to restore factory-spec timing and thermal response to your customer's HVAC unit.

• Precise Millivolt Output: Ensures consistent communication with the gas valve to prevent unexpected furnace shutdowns.
• Universal ICP Compatibility: Fits various models under the Heil, Tempstar, Arcoaire, and Comfortmaker brands.
• Optimized 24-Inch Length: Provides ample reach for standard pilot light configurations, allowing for clean wire routing away from high-heat zones.
• High-Durability Construction: Built with high-quality thermocouple wire to resist oxidation and thinning in the burner's flame path.

• Why does my pilot flame go out as soon as I release the reset button? This often indicates the thermocouple is not generating the required millivolts to hold the valve open, requiring a replacement like the 100241.
• Is this compatible with my older Heil furnace? Yes, the ICP 100241 is the official OEM replacement for numerous older part numbers, including 24002305 and 1490600.
• How do I test if this thermocouple is faulty? Use a multimeter to measure the DC millivolt output (unloaded) while the tip is heated; most HVAC technicians look for a reading between 25 and 30mV.
