International Comfort Products PYPA36GA1 Flame Sensor
The flame sensor is one of the safety features that senses the exact 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 until the problem is fixed.
What happens when my primary flame sensor is on its last leg?
- The unit will sort of operate on certain occasions whenever it pleases
- The gas that has entered the furnace has a tough time trying to start an ignition sequence and the board throws an error
- The furnace cannot work at all
