Samsung AVMWC020CA0 Defrost Sensor Board
The defrost control board is jobbed with determining when to begin the defrost sequence which helps to rid your unit of frost that can build up. The defrost board depends on a temperature sensor located in the outdoor unit to agree when to initiate the defrosting cycle.
Key indicators that my AC defrost sensor board is about to stop working?
- The defrost sequence will not kick in despite that there is a large amount frost that needs to be removed
- The main circuit board could display an error code produced by too much frost
- The HVAC system could stop running for the simple fact of frost blocking the airflow outside
