Goodman ARUF Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrosting phase which aids to continue normal heating and cooling operations. The control board depends on a defrost sensor which is near the condenser somewhere, in order to decide when the defrost cycle should begin.
Major indications your outdoor defrost sensor board has little life left
- Your main control board might issue an error number produced by too much frost
- The defrost sequence refuses to initiate even when there is a large quantity of frost built up
- Air conditioning may cease to operate for the fact of lack of airflow through the outdoor unit
