International Comfort Products GPSM36H100F Flame Sensor
The flame sensor is a safety feature that can reliably detect the proper flame when the system starts. For obvious reasons, if the flame sensor gets set off the whole system stops until the problem is dealt with.
Signals of an ineffective flame sensor
- Your system is unwilling to fire up and completely shuts down
- The entire heating system turns on infrequently but only on the third Wednesday of on months beginning on Thursday
- The gas supplying the furnace will not even try to properly ignite and the system throws an error code
