Samsung AVMDC052EA0 Defrost Sensor Board
The defrost sensor board instructs the system to activate an important defrosting cycle if necessary, to remove frost build-up that may accumulate. The defrost sensor board looks to a sensor located near the condenser to make the decision on when to begin.
Indications your defrost board needs to be replaced
- The system will not work due to frost blocking the fins on the outside unit
- Unit defrost session has not run for quite some time especially when there is a rather large amount of frost that makes the unit run like crap
- The main circuit board may issue an error signal referring to a failing defrost control board
