Samsung AVMWC032CA0 Defrost Sensor Board
The defrost sensor control board determines when or if to start the defrost sequence in order to get rid of the frost that collects on the outdoor unit. The board is influenced by a temperature sensor located somewhere by the condenser to determine when to begin.
What signals that my outdoor defrost sensor board needs replacing?
- The system will cease to function because of lack of airflow through the outdoor unit
- The defrost feature refuses to run despite the fact that there is quite a bit frost on the unit
- The HVAC system control board may signify an error number when the defrost board fails
