International Comfort Products GNE125J20A1 Flame Sensor
A flame sensor is one of the safety features that will sense the correct flame in accordance with the initial ignition sequence. As with most devices used for safety reason, if the flame sensor is triggered the furnace will not start until the problem is remedied and the system is reset.
Subtle cues of an unhealthy flame sensor
- The gas supplying the furnace refuses to burn and closes the gas valve
- The furnace cannot start when you want it to
- The heating system runs occasionally only after the second full moon of the month on a Tuesday
