Samsung AVMBC072CA0 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrosting phase if necessary, to defrost your outdoor unit. It is relayed information from a temperature sensor located somewhere by the condenser to agree when to begin.
Clues to watch for to know your Samsung defrost sensor board will need replacing
- The whole system may stop functioning at all because of the frost blocking the flow of air
- The primary control board may signify an alphanumeric error code referring to the failed defrost sequence
- Defrost session has not run for quite some time especially when there is frost that has built up
