Mitsubishi PKA-A12HAL Defrost Sensor Board
The defrost sensor control board commences the defrost sequence which helps to keep your outdoor unit from plugging up. The defrost sensor board is relayed information from a specific sensor located somewhere by the condenser to decide when to initiate the defrosting cycle.
Important signs your defrost board will die soon
- The main control board could throw an alphanumeric error code referring to a failing defrost control board
- Air conditioning may not operate due to the fact of lack of airflow through the outdoor unit
- Self defrost sequence never begins especially when there is frost that has built up
