Samsung AVMWH035EA0 Defrost Sensor Board
The defrost sensor control board initiates the defrosting phase which helps to keep your outdoor unit from plugging up. The control board relies on a sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
Some clues your defrost board should need replacing
- The main control board might give out a particular error code when the defrost control board refuses to initialize properly
- Defrost mode refuses to run even though there is a large amount of frost that has built up
- Most systems will not run for the simple fact of the frost issue
