Samsung AVMKC026EA0 Defrost Sensor Board
The defrost control board will determine when to initiate the defrosting phase if necessary, to rid your unit of frost that can build up. The defrost board looks to a temperature sensor located somewhere by the condenser to make the decision on when the defrost cycle should begin.
Subtle hints the AC defrost sensor board is in dire need of a replacement
- The system may not operate for the fact of the safety issue that the frost poses
- The HVAC system control board might give out a specific error code when a defrost board fails to initialize
- The defrost sequence never kicks in despite the fact that there is a lot of frost that has built up
