Lennox OF24-140 Flame Sensor
The flame sensor is an important safety feature that can sense the acceptable flame in accordance with the initial ignition sequence. As expected, when the flame sensor is activated the system will halt until the problem is fixed.
Clues of a weakening flame sensor
- HVAC system runs rarely when it wants to
- The gas that has entered the furnace will not begin an ignition sequence and shuts off
- The furnace refuses to even start at all
