Bryant 373LAV Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will consistently detect the appropriate flame during ignition. As you would probably could have guessed, if the sensor goes off everything stops until the problem is dealt with.
Major indications your safety flame sensor will soon need to be replaced
- The unit works occasionally when the time is right
- The type of gas you use finds it impossible to begin igniting no matter what
- Your heating system cannot start when you want it to
