Carrier 38YDB048 Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that will consistently detect the precise flame when the system starts. As with other safety devices, when the flame sensor is activated the furnace will not start until the problem is fixed.
Cues to watch for in a bad primary flame sensor
- Your gas furnace will not ramp up and completely shuts down
- Any type of gas that has entered the furnace cannot begin an ignition sequence no matter what
- The furnace will operate on certain occasions at the stroke of midnight after the second full moon following the second Sunday of the month
