International Comfort Products N8MPN125J20A1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle in order to rid your unit of frost that can build up. The defrost sensor board is influenced by a defrost sensor that can be found near the condenser, in order to decide when to begin.
Important clues of a poorly performing International Comfort Products defrost sensor board
- Self defrost sequence does not run despite the fact that there is quite a bit frost built up
- Your system could not operate due to frost blocking the fins on the outside unit
- The primary control board could display an alphanumeric error code produced when the defrost control board fails to receive a signal
