Goodman GDH80904BXCB Defrost Sensor Board
The defrost control board will begin an important defrosting cycle which aids to get rid of the frost that collects on the outdoor unit. The control board depends on a defrost sensor that can be found near the condenser, in order to make the decision on when to begin.
Subtle cues of an ineffective defrost board
- The defrost feature never initiates despite the fact that there is a lot of frost on the external unit
- Your main control board may throw a type of error code produced when the defrost board is bad
- The whole system may stop functioning for the simple fact of lack of airflow through the outdoor unit
