Samsung AVMWC052EA0 Defrost Sensor Board
The defrost sensor control board determines when to initiate the defrost cycle which helps to keep your outdoor unit from plugging up. The control board looks to a temperature sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Major clues your outdoor defrost sensor board is in need of replacing
- The defrost sequence refuses to run especially when there is frost in the way
- The system will not run due to the fact of the safety issue that the frost poses
- The main control board might issue an error signal if the defrost board fails
