Lennox CBX27UH-060 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will reliable sense the flame during ignition. As expected, if the flame sensor gets set off everything remains shut off until the problem is repaired.
Simple signals your furnace flame sensor has very little life left
- The whole system works occasionally when it feels like it
- The gas furnace cannot ramp up and shows an error code on the board
- LP or natural gas will not even try to begin an ignition sequence and shut down
