Lennox XP19-048 Flame Sensor
The flame sensor is an important safety feature that will dependably sense the flame in accordance with the initial ignition sequence. Due to safety concerns, if the flame sensor gets set off the furnace will not start until the problem is dealt with.
Clues to watch for to know your safety flame sensor is dying
- The type of gas you use has problems trying to begin igniting and some type of error flashes on the main board
- The heating system starts sometimes only after the second full moon of the month on a Tuesday
- The furnace will not even start when you crank the thermostat up
