The Bard 8620-223 Defrost Board Replacement Kit is an OEM control used in Bard package heat pump equipment to manage the defrost cycle so the outdoor coil can clear frost buildup and maintain steady heating performance in cold, damp conditions. When the existing defrost control fails or becomes unreliable, this Bard replacement kit helps restore proper defrost timing and operation, reducing nuisance icing and protecting overall system efficiency. Because defrost controls can vary by model and series, confirm part number 8620-223 against your unit data plate and the Bard parts list for your specific equipment before ordering.
