Lennox HP13-036 Flame Sensor
A flame sensor is a safety device that will sense the precise flame when the system starts. As with other safety devices, if the flame sensor is triggered the whole HVAC system will remain stopped until the problem is dealt with.
Major signs the Lennox flame sensor is dead
- The type of gas you use finds it impossible to begin an ignition sequence and some type of error flashes on the main board
- The unit operates sporadically only after the second full moon of the month on a Tuesday
- The heat system refuses to generate heat at all
