The defrost sensor board will determine when to initiate the defrosting phase which helps to continue normal heating and cooling operations. It is influenced by a sensor located near the condenser to ascertain when to begin.
Major signs to watch for in a failing Friedrich defrost sensor board
- Defrost mode refuses to initiate even though there is excessive frost on the external unit
- The main board could display an alphanumeric error code produced when the defrost control board fails to receive a signal
- Your system could not operate due in part to frost blocking the airflow outside
