Description
The Trane SEN00297 Flame Sensor is an essential sensing component used in gas-fired systems to detect the presence of a burner flame during operation. It is installed near the burner assembly in compatible furnaces. It continuously checks for flame ionization and sends a signal to the control board to confirm safe combustion in HVAC systems. If no flame is detected, the sensor supports initiating a shutdown sequence to avoid unburned gas from accumulating. It is commonly used in commercial heating systems, where it operates as part of the safety control circuit that manages ignition checking and overall burner operation accuracy.
