International Comfort Products PAMC36HA Flame Sensor
A flame sensor is only found on gas furnaces. It is a sensor that can reliably detect the precise flame while the system is starting. Because of the safety issues involved, if the flame sensor gets set off everything stops until the problem is repaired.
Some clues of a declining primary flame sensor
- System runs occasionally when the time is right
- The gas that has entered the furnace will not ignite and the main board displays on error code
- The furnace will not fire up when you crank the thermostat up
