Lennox HPXB15-042 Flame Sensor
The flame sensor is only found on gas furnaces. It is a sensor that will consistently detect the precise flame during ignition. Due to the overall safety issue, when the sensor is triggered by an event the whole HVAC system will remain stopped for as long as it takes to remedy the problem.
What are some indications that my safety flame sensor is about to go out?

- The heating system will not begin operations at all
- The unit runs occasionally only after the second full moon of the month on a Tuesday
