Haier HPR09XC5 Defrost Sensor Board
The defrost control board instructs the system to activate the defrosting phase which may be needed in order to remove frost build-up that may accumulate. The board is relayed information from a defrost sensor that can be found near the condenser, in order to make the decision on when the defrost cycle should begin.
General indicators that your your outdoor defrost sensor board will die soon
- Your main control board might give out an error signal produced by too much frost
- The defrost feature refuses to initiate especially when there is frost that makes the unit run like crap
- Air conditioning may stop functioning for the fact of lack of airflow through the outdoor unit
