LG LMAN120CNS Flame Sensor
The flame sensor is a regulatory sensor that can sense the acceptable flame during the initial ignition of the furnace. As you would probably could have guessed, if the sensor produces an error the system remains completely shut down for as long as it takes to remedy the problem.
Major signs of a weak safety flame sensor
- The heat system cannot work and completely shuts down
- The unit will work intermittently barely
- The propane or natural gas finds it impossible to begin igniting and the control shows an error
