Nordyne E3EX Defrost Sensor Board
The defrost sensor board initiates an important defrosting cycle which may be necessary to get rid of the frost that collects on the outdoor unit. The control board is influenced by a sensor which is near the condenser somewhere, in order to make the decision on when to begin.
Major warnings of a weak outdoor defrost sensor board
- Self defrost sequence has not run for a while despite the fact that there is quite a bit frost that makes the unit run like crap
- The main board might give out an alphanumeric error code produced by a bad defrost control board
- The AC may not work because of frost blocking the airflow outside
