Payne PY2PNB048115AA Defrost Sensor Board
The defrost sensor board determines when or if to start the defrost cycle which may be needed in order to continue normal heating and cooling operations. The defrost sensor board looks to a specific sensor located in the outdoor unit to make the decision on when to initiate the defrosting cycle.
Major clues of a defective defrost sensor board
- Defrosting does not begin even though there is a lot of frost that has built up
- The system may cease to operate because of lack of airflow through the outdoor unit
- Your main control board could signify an error signal if the defrost board fails
