Carrier FY4ANF018000 Flame Sensor
A flame sensor is one that will consistently detect the appropriate flame during the initial ignition of the furnace. As with most devices used for safety reason, when the flame sensor gets triggered by something everything stops until the main issue is remedied.
Key symptoms of a bad Carrier flame sensor
- The whole system will sort of operate sporadically when the time is right
- Your heating system will not even begin to start and completely shuts down
- The gas that has entered the furnace has a tough time trying to ignite and the whole system shuts down
