Goodman GPH1342H21A Defrost Sensor Board
The defrost sensor board instructs the outdoor unit to begin the defrosting phase which helps to rid your unit of frost that can build up. The defrost sensor board relies on a defrost sensor located somewhere by the condenser to ascertain when the defrost cycle should begin.
Major indications of an ailing defrost board
- The control board could display a particular error code produced by a failing defrost board
- The AC may cease to function for the simple fact of the frost blocking the flow of air
- Unit defrost session never runs despite the fact that there is quite a bit frost built up
