Lennox R22 Flame Sensor
The flame sensor is a regulatory sensor that can sense the acceptable flame upon ignition. Due to the overall safety issue, if the flame sensor senses a problem the furnace will not start until the problem is repaired.
Some warnings your furnace flame sensor will die soon
- The gas that has entered the furnace refuses to properly ignite no matter what you do
- The heating system will sort of operate sporadically at midnight, but only after the new moon following the fourth Monday of the month
- The gas furnace is unable to start operating when the control board tells it to
