Frigidaire FRP77ETT3R0 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that can reliably detect the correct flame during ignition. As you would probably could have guessed, when the flame sensor gets triggered by something the system remains completely shut down until that particular problem is fixed.
Signals the Frigidaire flame sensor has little life left
- The gas entering the furnace cannot burn no matter what
- The entire heating system will work infrequently when it thinks it should
- Your gas furnace will not produce any heat and will shut everything down
