The defrost board monitors outdoor coil temperature and elapsed run time, then initiates and terminates the defrost cycle to prevent frost and ice accumulation on the outdoor coil. When this board fails, the heat pump may run in a near-continuous defrost loop, refuse to enter defrost at all, or ice over completely — dramatically reducing heating efficiency and risking compressor damage.
