Fujitsu AOU12RL2 Defrost Sensor Board
The defrost sensor board controls if and when to commence an important defrosting cycle which actually helps to keep your outdoor unit from plugging up. The defrost sensor board relies on a temperature sensor located somewhere by the condenser to make the decision on when to begin.
How do you know when your defrost board is almost dead?
- AC and heating system could not run because of lack of airflow through the outdoor unit
- The defrost sequence never begins despite the fact that there is quite a bit frost on the external unit
- The main control board could signify an alphanumeric error code when the defrost control board refuses to initialize properly
