LG ARUN160LT2 Flame Sensor
A flame sensor is only used on furnaces that burn gas and is one that will dependably sense the appropriate flame when igniting the system. As with most safety features, when the flame sensor is activated the gas valve is shut off and the system halts until the problem is dealt with.
What warnings should I watch out for to know if my furnace flame sensor is in need of a replacement?
- Your furnace will not supply heat and will shut everything down
- The propane or natural gas has a tough time trying to ignite no matter what you do
- The entire heating system starts rarely barely
