Carrier 50JX042300 Flame Sensor
A flame sensor is only found on gas furnaces. It is a sensor that will consistently detect the precise flame during the initial ignition of the furnace. As with most safety features, when the flame sensor is activated everything stops for as long as the problem remains.
Clues to watch for to know your furnace flame sensor is on its last leg
- The heat system is unwilling to produce heat at all
- The propane or natural gas has problems trying to ignite no matter what
- The unit will sort of operate rarely whenever it pleases
