Samsung APC3240C Defrost Sensor Board
The defrost sensor control board determines when to initiate the defrost cycle which actually helps to rid your unit of frost that can build up. The defrost board is influenced by a specific sensor that can be found near the condenser, in order to make the decision on when to begin.
Some clues of a weakening AC defrost sensor board
- The AC may stop operating at all because of the frost issue
- The HVAC system control board may issue an alphanumeric error code produced by too much frost
- The defrost feature refuses to initiate even though there is excessive frost built up
