NewAir AC-14100H Flame Sensor
The flame sensor is a safety device that senses the flame during the initial ignition of the furnace. As with other safety devices, if the sensor produces an error everything comes to a halt for as long as the problem remains.
Clues to watch for to know the primary flame sensor needs replacing
- The heat system is unwilling to ramp up and will shut everything down
- The heating system works occasionally but only on the third Wednesday of on months beginning on Thursday
- The propane or natural gas will not start an ignition sequence and the board throws an error
