Samsung AVMWH070EA0 Defrost Sensor Board
The defrost control board commences the defrost sequence which may be needed in order to continue normal heating and cooling operations. The defrost sensor board depends on a specific sensor located somewhere by the condenser to determine when to begin.
What are some hints that my outdoor defrost sensor board needs replacing?
- The primary control board could display a specific error code produced when the defrost control board fails to receive a signal
- Defrost mode never runs especially when there is a rather large amount of frost on the external unit
- AC and heating system could not operate due to the fact of the amount of frost on the outdoor unit
