LG ARNU123SER2 Flame Sensor
A flame sensor is one that senses the acceptable flame upon ignition. As with any other safety sensor, when the flame sensor gets triggered by something the system will halt until the problem is fixed.
What are some indications that my furnace flame sensor is about to stop working?
- The furnace is unable to even start at all
- The entire heating system will work rarely at the stroke of midnight after the second full moon following the second Sunday of the month
- The LP or natural gas refuses to properly ignite and the whole system shuts down
