International Comfort Products CHP218GKA1 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that senses the appropriate flame during the initial ignition of the furnace. As with most safety features, if the flame sensor gets set off the system remains completely shut down until the problem is dealt with.
Key clues of a weakening flame sensor
- The heating system refuses to generate heat and will shut everything down
- The whole system starts occasionally when it feels like it
- The gas entering the furnace has difficulty trying to ignite and the system throws an error code
