Frigidaire FRS123LW11 Defrost Sensor Board
The defrost sensor control board determines when or if to start an important defrosting cycle which aids to defrost your outdoor unit. The board is influenced by a sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Key signs to watch for in a bad defrost sensor board
- The defrost sequence has not run for quite some time despite the fact that there is a lot of frost that needs to be removed
- The primary control board may show an error signal if the defrost board goes out
- The system may stop running for the simple fact of frost blocking the airflow outside
