International Comfort Products GPFM48H080F Flame Sensor
The flame sensor is one that can reliably detect the flame during the initial ignition of the furnace. For obvious reasons, when the sensor is triggered by an event everything stops until the problem is dealt with.
Indications the primary flame sensor needs to be replaced
- The LP or natural gas will not begin an ignition sequence no matter what
- The heat system is unwilling to even start and spits out an error code on the main board
- HVAC system will run on certain occasions when it feels like it
