Goodman GKS90453BXAB Defrost Sensor Board
The defrost sensor control board instructs the outdoor unit to begin the defrost cycle which may be necessary to defrost your outdoor unit. The board is relayed information from a sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Some clues your defrost board is failing
- The defrost feature has not run for quite some time despite the fact that there is quite a bit frost on the unit
- The main circuit board could signify an error signal produced by too much frost
- The whole system may stop working because of the fact that there is too much frost
