Refrigerator schematics are useful to a technician attempting to diagnose and repair an appliance, reports Acme How To. Every refrigerator is wired differently and technicians do not have them all committed to memory.
A schematic diagram provides an illustration of everything relevant to the electrical or electronic operation of a refrigerator including the motors, switches, controls, wiring and any other components. It indicates the paths of wires and their connections to the refrigerator's components.
Schematic diagrams for refrigerators are typically found on the back of the refrigerator, in an envelope behind the toe kick on the front of the unit or glued to an inside panel on the lower rear of the refrigerator, according to Acme How To.
