The defrost control board monitors outdoor coil conditions and automatically initiates timed defrost cycles to prevent ice accumulation on the evaporator coil. When this board fails, you'll typically see persistent frost or ice buildup on the outdoor unit, the system stuck in continuous defrost mode, or a heat pump that delivers little to no heat on cold days.
