International Comfort Products NBF075F16A1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle which may be needed in order to remove frost build-up that may accumulate. It depends on a specific sensor located in the outdoor unit to decide when to begin.
Simple warnings that your outdoor defrost sensor board is almost going bad?
- The system will stop working due to the fact of way too much frost build-up
- The defrost sequence refuses to run despite that there is a large amount frost on the unit
- The main control board might give out an error of some type referring to a bad defrost board
