Nordyne 903600 Flame Sensor With Wiring Harness

The Nordyne 903600 Flame Sensor is a crucial safety component in Nordyne gas-fired HVAC systems. It continuously monitors the presence and temperature of the flame within the burner assembly. By detecting a flame within the expected range of 600°F to 1800°F, the sensor ensures safe and efficient combustion. If the flame weakens, goes out, or exceeds the safe temperature range, the sensor signals the control board to shut down the gas supply. This critical function prevents gas leaks and potential hazards like fires or carbon monoxide poisoning. The compact size of the sensor, measuring 2 inches by 0.5 inches by 0.1 inches, allows for easy installation within the HVAC unit.
