Carrier KLA Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle which helps to get rid of the frost that collects on the outdoor unit. The defrost sensor board is relayed information from a specific sensor located in the outdoor unit to ascertain when to begin.
Major symptoms your defrost board is in dire straights
- The system will not work at all because of frost blocking the airflow outside
- The control board may issue a specific error code if the defrost control board fails
- The defrost sequence will not initiate despite the fact that there is quite a bit frost that needs to be removed
