International Comfort Products N8MPL075B12A1 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle which helps to remove frost build-up that may accumulate. The board is influenced by a specific sensor located near the condenser to decide when to initiate the defrosting cycle.
What are the signs that the outdoor defrost sensor board is about to stop working?
- Defrost session never kicks in even though there is excessive frost built up
- Your main control board might give out a particular error code referring to a bad defrost board
- The system may stop working for the simple fact of lack of airflow through the outdoor unit
