York S1-373-23867-001 Yorkguard 1-Stage Defrost Module

The York S1-373-23867-001 Yorkguard 1-Stage Defrost Module is a essentialcomponent that a heat pump requires to operate efficiently. This module only controls the defrost cycle in order to focus on getting the results when operating at low temperatures. 1-Stage Defrost Module employs the detection of frosting on the outside heat pump coil. In addition, it initiate the defrost cycle whenever necessary, to warm the evaporator by letting the refrigerant flow in the opposite direction for a short while. The process eliminates potential dangers associated with ice formation as well as protects heat pumps from reduced effectiveness.
