LG LP120CM3 Flame Sensor
The flame sensor is a regulatory sensor that will consistently detect the correct flame during ignition. Due to the overall safety issue, when the sensor is triggered by an event the furnace cannot start again until that particular problem is fixed.
Important signs the LG flame sensor is dead
- Your heating system is unwilling to begin working and will shut everything down
- The propane or natural gas refuses to try to begin an ignition sequence and closes the gas valve
- The furnace will start intermittently barely
