National Comfort Products 14208318 Flame Sensor
Ensure reliable ignition and prevent nuisance lockouts with the National Comfort Products 14208318 Flame Sensor. This OEM furnace flame sensor is a critical safety component designed for flame rectification, passing a microamp (µA) DC signal back to the integrated furnace control once the burner is established. When your system experiences brief ignition followed by an immediate shutdown, carbon fouling or silica buildup on the sensor rod is often the culprit, creating resistance that interrupts the flame proving sequence.
Built as a direct replacement flame sensor for National Comfort units, the 14208318 features a high-grade stainless steel rod and a robust porcelain insulator to withstand intense thermal stress. Proper installation requires a secure mount to maintain a precise ground circuit, which is essential for accurate signal transmission to the HVAC control board. Replacing a degraded or cracked sensor restores consistent operation and protects against dangerous gas accumulation during the ignition cycle.
Key Benefits- Precise Flame Sensing: Delivers accurate microamp readings to prevent short-cycling and safety lockouts.
- OEM Compatibility: Specifically engineered for National Comfort Products heating modules for seamless fitment.
- Thermal Durability: High-temperature rod construction resists oxidation and warping in the burner path.
- Critical Safety: Acts as the primary safeguard by signaling the gas valve to close if no flame is detected.
- What is the typical microamp reading for this sensor? Most control boards look for a minimum signal of 0.5 to 1.0 µA, though 2.0 to 6.0 µA is standard during healthy operation.
- Can I clean this sensor instead of replacing it? While temporary cleaning with light steel wool can restore signal, it often removes the protective finish, leading to faster carbon buildup; total replacement is the standard professional fix.
- How do I verify the sensor is the problem? If the burners light but shut down within 3-5 seconds, use a multimeter in series with the sensor wire to check for a drop in DC current.
