International Comfort Products NDC7050BFA1 Defrost Sensor Board
The defrost control board instructs the outdoor unit to begin the defrost sequence which aids to get rid of the frost that collects on the outdoor unit. The defrost sensor board is relayed information from a specific sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
What to see if the defrost board is about to go out?
- Defrost session refuses to run despite the fact that there is quite a bit frost on the external unit
- Your system could stop working due to the amount of frost on the outdoor unit
- The main control board might issue an error of some type produced by too much frost
