Heil Quaker ICP 1171449 Flame Sensor

The Heil Quaker ICP 1171449 Flame Sensor is a critical OEM replacement component designed for high-performance flame rectification in International Comfort Products (ICP) residential and commercial heating units. For technicians troubleshooting a furnace short cycling or ignition failure, this genuine ICP flame rod provides the precise feedback signal required by the integrated furnace control to maintain the gas valve circuit. Modern HVAC flame sensors like the 1171449 utilize the flame's conductivity to convert AC voltage into a DC microamp signal; a reading below 1.5 to 2.0 microamps typically indicates carbon buildup or sensor degradation, leading to a safety lockout. This 1171449 sensor is compatible with a wide range of Allied, Arcoaire, Comfortmaker, and Heil systems, including specific package units like the PGE036 series. As a veteran-grade HVAC ignition part, it features a high-temperature porcelain insulator and a durable stainless steel rod tip to withstand the harsh environment of the burner assembly while ensuring rapid flame detection during the crucial four-second proving window.

• Optimized Flame Rectification: Engineered to provide consistent DC microamp signals, preventing nuisance trips and furnace lockout codes.
• Broad ICP Compatibility: Direct replacement flame sensor for multiple brands under the International Comfort Products umbrella, reducing truck stock requirements.
• Industrial-Grade Construction: Features a robust porcelain terminal block and a 4.5-inch rod length designed for precise placement within the burner's flame path.
• Safety Standard Compliance: A genuine OEM furnace part that ensures the system adheres to original manufacturer safety sequences for gas flow.

• How do I test the 1171449 flame sensor? Set your multimeter to the microamp (?A) DC scale and wire the meter in series between the sensor terminal and the control board lead. A healthy signal should stay steady between 2 and 6 microamps.
• What are the symptoms of a failing flame rod? The most common sign is the furnace lighting for 2-5 seconds and then immediately shutting down, often repeating this cycle three times before a hard lockout.
• Can I clean this sensor instead of replacing it? While light oxidation can be removed with fine steel wool or a Scotch-Brite pad, any cracks in the porcelain insulator or significant pitting on the rod requires immediate replacement to ensure reliable operation.
