Panasonic CS-KS18NB4UW Defrost Sensor Board
The defrost sensor board will begin the defrost cycle which actually helps to continue normal heating and cooling operations. The defrost board relies on a defrost sensor which is near the condenser somewhere, in order to ascertain when the defrost cycle should begin.
What are the signs that the AC defrost sensor board needs replacing?
- The primary control board might issue an error number produced when the defrost board is bad
- Defrost session never begins despite the fact that there is quite a bit frost on the external unit
- Most systems will cease to operate due to frost blocking the airflow outside
