Panasonic CS-XE12PKUA Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle which may be necessary to rid your unit of frost that can build up. It depends on a sensor which is near the condenser somewhere, in order to ascertain when to begin.
Major signs of a weakening outdoor defrost sensor board
- Defrost session refuses to initiate despite the fact that there is quite a bit frost that has built up
- The HVAC system could stop working due to frost blocking the fins on the outside unit
- The HVAC system control board could display an error signal referring to the failed defrost sequence
