Carrier 48XZ036090300TP Flame Sensor
The flame sensor is one of the safety features that can reliably detect the acceptable flame when igniting the system. As with most safety features, if the flame sensor is triggered the entire HVAC system will stop until obstacle is corrected.
What symptoms are present when the Carrier flame sensor really needs to be replaced?
- The heat system will not produce any heat when the control board tells it to
- The LP or natural gas finds it impossible to begin igniting and the board throws an error
- The whole system will start infrequently only after the second full moon of the month on a Tuesday
