Goodman GCH90904CX Defrost Sensor Board
The defrost sensor control board initiates the defrosting phase which actually helps to get rid of the frost that collects on the outdoor unit. It is relayed information from a temperature sensor located somewhere by the condenser to make the decision on when to begin.
Hints of a poorly performing AC defrost sensor board
- Unit defrost session never initiates despite that there is a large amount frost built up
- The main circuit board may signify a specific error code when the defrost control board refuses to initialize properly
- Most systems will not operate because of the frost blocking the flow of air
