A flame sensor is a safety device that can reliably detect the precise flame in accordance with the initial ignition sequence. As you would probably could have guessed, if the sensor generated a error the furnace cannot start again for as long as the problem remains.
Major symptoms the primary flame sensor should need replacing
- The furnace operates sporadically whenever it pleases
- The gas entering the furnace will not start an ignition sequence no matter what you do
- The gas furnace is unable to fire up when the control board tells it to
