Samsung AVMHC128CA0 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost cycle in order to get rid of the frost that collects on the outdoor unit. The defrost sensor board looks to a sensor that can be found near the condenser, in order to make the decision on when to initiate the defrosting cycle.
Elements of a bad defrost board
- The whole system may not operate due in part to the frost blocking the flow of air
- The defrost feature never runs even though there is a lot of frost in the way
- Your main control board may show a type of error code produced by too much frost
