LG ARNU073TJC2 Flame Sensor
The flame sensor is a regulatory sensor that will consistently detect the correct flame when igniting the system. Due to the overall safety issue, when the sensor is triggered by an event the whole system stops until obstacle is corrected.
What are the clues to watch out for to know my furnace flame sensor needs replacing?
- Your furnace will not fire up and will shut everything down
- The heating system will start intermittently but only on the third Wednesday of on months beginning on Thursday
- LP or natural gas refuses to burn and the main board displays on error code
