Description
The York S1-33101975102 Defrost Control Board Kit is an essential part of commercial and industrial HVAC systems. This board is used to control the defrost cycle in heat pump systems to guarantee their smooth operation during cold climates. At some point, when the outside temperatures are low, the heat pump’s outdoor coil can freeze over and this better diminishes its ability to heat. The defrost control board checks on several other sensors, for instance, temperatures or pressures in controlling the defrost cycle.
