Carrier 30GT Defrost Sensor Board
The defrost control board commences the defrost sequence which aids to get rid of the frost that collects on the outdoor unit. The board relies on a defrost sensor located somewhere by the condenser to verify when to begin.
What are the clues to watch out for to know my outdoor defrost sensor board needs replacing?
- The main control board may issue an error signal if the defrost board goes out
- Your system could end up not running due in part to the safety issue that the frost poses
- Defrost session never kicks in even though there is a large amount of frost built up
