Payne PG8JAA048070AAJA Defrost Sensor Board
The defrost control board controls when to launch the defrost sequence which aids to rid your unit of frost that can build up. It is influenced by a specific sensor which is near the condenser somewhere, in order to verify when the defrost cycle should begin.
Main clues your Payne defrost sensor board will need replacing
- The system will cease to operate because of lack of airflow through the outdoor unit
- Defrosting will not kick in especially when there is frost that needs to be removed
- The main circuit board may throw a type of error code if the defrost board fails
