Carrier 48XL-A48 Flame Sensor
The flame sensor is a vital part that will sense the correct flame in accordance with the initial ignition sequence. As you would probably could have guessed, if the sensor produces an error the whole HVAC system will remain stopped until the problem is fixed.
Signs your flame sensor is in dire straights
- The entire heating system turns on on certain occasions at the stroke of midnight after the second full moon following the second Sunday of the month
- The LP or natural gas refuses to begin igniting and the board throws an error
- Your system will not ramp up whatsoever
