Lennox G40DF-24A-045 Flame Sensor
A flame sensor is a contraption that will sense the proper flame while the system is starting. Due to the overall safety issue, if the sensor generated a error the whole HVAC system will remain stopped until the problem is dealt with.
What to see if the primary flame sensor is about to stop working?
- The heating system cannot fire up when you want it to
- The LP or natural gas cannot begin igniting and the main board displays on error code
- HVAC system runs sporadically when the time is right
