Nordyne E3EB-012H Defrost Sensor Board
The defrost sensor board initiates the defrosting phase which actually helps to continue normal heating and cooling operations. The defrost board looks to a temperature sensor which is near the condenser somewhere, in order to determine when to initiate the defrosting cycle.
Some clues your defrost board is in need of replacing
- Unit defrost session never starts even though there is a large amount of frost on the unit
- Your system could stop running due in part to the frost blocking the flow of air
- The control board could signify an alphanumeric error code if the defrost control board fails
