Goodman GKS90703BXAC Defrost Sensor Board
The defrost control board instructs the system to activate the defrost cycle which helps to continue normal heating and cooling operations. The control board is influenced by a temperature sensor located somewhere by the condenser to agree when to initiate the defrosting cycle.
Major clues to watch for in a bad outdoor defrost sensor board
- The defrost sequence never begins despite the fact that there is a lot of frost on the external unit
- The primary control board might give out an error of some type when the defrost board fails
- AC and heating system could stop functioning due to frost blocking the airflow outside
