Samsung AFPCC052CA0 Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost sequence in order to get rid of the frost that collects on the outdoor unit. The control board relies on a specific sensor which is near the condenser somewhere, in order to decide when to begin.
How can I tell if my defrost board is dying?
- Defrost mode never runs especially when there is a rather large amount of frost that makes the unit run like crap
- The main circuit board could throw a particular error code if the defrost board fails
- The system may end up not running for the simple fact of too much frost
