Description
The Lennox 17M14 Defrost Control Board is an essential part of Lennox HVAC units, particularly furnaces. It protects the system from getting inefficient and possibly damaged by controlling the defrost cycle. This cycle occasionally defrosts the ice that forms on the evaporator coil during its functioning. The evaporator coil gets hold of heat in air and moisture in air will freeze on the surface of the coil if it is not regulated. Ice formation obstructs air passage and limits the capacity of the system to cool your house. The 17M14 Defrost Control Board enhances efficiency by starting defrost cycles at the right time.
