Fujitsu AOU18RLXFZ Flame Sensor
A flame sensor is one of the safety features that can sense the proper flame in accordance with the initial ignition sequence. As with most safety features, if the sensor produces an error the whole HVAC system will remain stopped until that particular problem is fixed.
What warnings should I watch out for to know if my Fujitsu flame sensor has to be replaced?
- The main type of gas has a tough time trying to burn and shut down
- Your system is unable to produce any heat at all
- The entire heating system works occasionally when the time is right
