Lennox XP14-048 Flame Sensor
The flame sensor is a regulatory sensor that will dependably sense the proper flame while the system is starting. As expected, if the flame sensor gets set off everything comes to a halt until the problem is remedied and the system is reset.
Key signs of an unhealthy primary flame sensor
- The gas that has entered the furnace has a tough time trying to properly ignite under any circumstance
- The unit will operate rarely only after the second full moon of the month on a Tuesday
- The furnace is unable to work when the control board tells it to
