Whirlpool ATR1243CPP0 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can reliably detect the acceptable flame during the initial ignition of the furnace. As you would probably could have guessed, when the flame sensor is activated everything remains shut off for as long as the problem remains.
Chief elements of a weak Whirlpool flame sensor
- The propane or natural gas has difficulty trying to begin igniting and the board throws an error
- Your heating system refuses to produce heat and spits out an error code on the main board
- The whole system will run sporadically but only on the third Wednesday of on months beginning on Thursday
