International Comfort Products NDC7050BFA3 Defrost Sensor Board
The defrost sensor control board instructs the system to activate the defrost sequence in order to remove frost build-up that may accumulate. It is influenced by a defrost sensor located somewhere by the condenser to decide when the defrost cycle should begin.
Major symptoms of a poorly performing defrost sensor board
- The main board could signify a type of error code referring to the failed defrost sequence
- The whole system may stop working for the fact of the safety features installed
- Defrost session never starts despite the fact that there is quite a bit frost on the external unit
