Samsung AVMDC052CA0 Defrost Sensor Board
The defrost sensor control board will begin the defrost sequence which may be necessary to rid your unit of frost that can build up. It is relayed information from a temperature sensor which is near the condenser somewhere, in order to verify when to begin.
Key signs of an ailing defrost sensor board
- Most systems will stop functioning due to the frost blocking the flow of air
- The HVAC system control board might give out an alphanumeric error code produced when the defrost control board fails to receive a signal
- The defrost sequence does not run despite that there is a large amount frost on the external unit
