Goodman ATUF363616 Flame Sensor
A flame sensor is a safety feature that can reliably detect the acceptable flame in accordance with the initial ignition sequence. As you would probably could have guessed, when the flame sensor gets triggered by something the furnace cannot start again until the problem is remedied and the system is reset.
Simple signals the primary flame sensor is in need of replacing
- Your furnace cannot generate heat and will shut everything down
- The gas refuses to begin igniting and the board throws an error
- The furnace starts occasionally when it wants to
