Carrier 48XP036090300 Defrost Sensor Board
The defrost control board initiates the defrost sequence which actually helps to remove frost build-up that may accumulate. The defrost sensor board is influenced by a temperature sensor located near the condenser to verify when the defrost cycle should begin.
What red flags are there that my Carrier defrost sensor board is on its last leg?
- The control board may signify an alphanumeric error code referring to the failed defrost sequence
- The system will stop functioning due in part to frost blocking the airflow outside
- The defrost feature never starts despite the fact that there is quite a bit frost built up
