LG A3UC363FA0 Flame Sensor
A flame sensor is one that will dependably sense the proper flame while the system is starting. As expected, if the flame sensor senses a problem the entire HVAC system will stop for as long as it takes to remedy the problem.
What warnings are present when my primary flame sensor is crapping out?
- The gas has problems trying to begin igniting no matter what you do
- The whole system will kind of run sometimes when the time is right
- The furnace will not work and completely shuts down
