International Comfort Products T8DNL125L20B1 Defrost Sensor Board
The defrost control board will determine when to initiate the defrosting phase in order to get rid of the frost that collects on the outdoor unit. The defrost board is influenced by a temperature sensor located in the outdoor unit to make the decision on when to initiate the defrosting cycle.
Simple warnings that your defrost board is in need of a replacement?
- The system may cease to operate due to the fact of too much frost
- The primary control board may issue an error number produced when the defrost board is bad
- The defrost feature never begins despite the fact that there is a lot of frost on the external unit
