International Comfort Products N9MP2075B12C2 Defrost Sensor Board
The defrost control board initiates the defrost sequence which aids to rid your unit of frost that can build up. It relies on a specific sensor that can be found near the condenser, in order to verify when to initiate the defrosting cycle.
General warnings of a laboring defrost board
- Defrost mode never starts despite that there is a large amount frost in the way
- The AC may cease to function for the simple fact of the amount of frost on the outdoor unit
- The main control board may issue an error of some type referring to the failed defrost sequence
