International Comfort Products FBF125J20A3 Flame Sensor
The flame sensor is a safety device that senses the correct flame in accordance with the initial ignition sequence. For obvious reasons, when the sensor is triggered by an event the system remains completely shut down until the problem is dealt with.
Red flags of a barely functioning flame sensor
- System will sometimes work infrequently whenever it pleases
- Your heating system refuses to even begin to start when you want it to
- The propane or natural gas refuses to begin igniting and shuts off
