The defrost control board instructs the outdoor unit to begin the defrost sequence which may be needed in order to defrost your outdoor unit. The defrost sensor board is relayed information from a defrost sensor located near the condenser to decide when to begin.
Major symptoms of a defective defrost board

- Unit defrost session never runs especially when there is a rather large amount of frost that needs to be removed
