Whirlpool ATR0943CPP0 Flame Sensor
The flame sensor is one that can reliably detect the appropriate flame upon ignition. As expected, if the sensor produces an error everything remains shut off until the main issue is remedied.
Some clues your furnace flame sensor is failing
- The gas entering the furnace has problems trying to burn and shut down
- The heating system will run infrequently at the stroke of midnight after the second full moon following the second Sunday of the month
- Your system will not work when you crank the thermostat up
