International Comfort Products GPCM48H080F Flame Sensor
The flame sensor is a safety device that can sense the proper flame while the system is starting. As with other safety devices, when the flame sensor gets triggered by something the furnace cannot start again until the problem is dealt with.
Indications your safety flame sensor will need replacing
- The whole system will work occasionally when it feels like it
- The gas that has entered the furnace has a tough time trying to start an ignition sequence and shuts itself off
- The furnace refuses to begin working no matter what
