Edgestar AP14009COM-1 Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrost sequence which assists to rid your unit of frost that can build up. The defrost sensor board relies on a temperature sensor that can be found near the condenser, in order to ascertain when to begin.
Some clues your outdoor defrost sensor board will have to be replaced
- The main board might give out an alphanumeric error code produced by a failing defrost board
- Your system could not work for the fact of the frost issue
- The defrost sequence never begins even though there is a large amount of frost built up
