International Comfort Products GPFM48H120F Flame Sensor
The flame sensor is a very important part of the safety feature set that senses the acceptable flame when the system starts. As you could guess, if the flame sensor gets set off the whole system stops until that particular problem is fixed.
Major clues your safety flame sensor is in dire need of a replacement
- The main type of gas has difficulty trying to burn under any circumstance
- The heating system works occasionally at the stroke of midnight after the second full moon following the second Sunday of the month
- The heating system refuses to fire up when the thermostat kicks in
