Refrigerators are one of the most important appliances in the modern home, and they have come a long way from their predecessors. While their basic operation has remained relatively unchanged, the wiring systems that power them have become more complex. Knowing how to read a wiring diagram of a refrigerator can help you diagnose any problems you may have, and save you time and money. In this guide we will explain the basics of refrigerator wiring diagrams, and the components they contain.

What is the Difference Between Electrical Wiring and Refrigerator Wiring?

When it comes to wiring, there is a big difference between electrical wiring and refrigerator wiring. Electrical wiring is typically used to power the various components of an electrical system, such as lights, receptacles, outlets, and appliances. Refrigerator wiring, on the other hand, is used to power the cooling and freezing systems of your refrigerator, and is much more specific to the particular make and model of your refrigerator.

What is a Refrigerator Wiring Diagram?

A refrigerator wiring diagram is a drawing that shows the various components that make up a refrigerator and how they are connected. It is usually included with the refrigerator when you buy it, but it can also be found in the refrigerator’s owner’s manual. A wiring diagram will typically include a list of the components and how they are connected, as well as a legend that lists the symbols used for the various components. It can also include a brief description of each component and its function.

What Components are Included in a Refrigerator Wiring Diagram?

A refrigerator wiring diagram will typically include the following components: the compressor, condenser, evaporator fan motor, defrost timer, thermostat, thermistor, and various electrical components. The compressor is the heart of the refrigerator and is responsible for compressing and circulating the coolant throughout the system. The condenser is the part of the refrigerator that cools the air inside it. The evaporator fan motor draws air from the inside of the refrigerator and blows it over the condenser coils to cool the air inside. The defrost timer is responsible for turning on and off the evaporator fan motor, and the thermostat is responsible for regulating the temperature inside the refrigerator. Finally, the thermistor is a temperature sensing device that helps the thermostat to maintain the desired temperature.

How to Read a Refrigerator Wiring Diagram

In order to read a refrigerator wiring diagram, you must first identify the symbols used to represent each component. Each component is typically represented by a unique symbol, which is usually a letter or a number. Once you have identified the symbols, you can then begin to trace the connections between the various components. This will help you to understand how the components are connected to each other, and how the entire system works.


Understanding how to read a wiring diagram of a refrigerator can be a great way to diagnose and troubleshoot any issues you may be having with your refrigerator. While the diagram may look intimidating at first, it is actually fairly simple to understand once you learn the symbols and trace the connections between the components. Hopefully this guide has given you the knowledge you need to confidently read and understand wiring diagrams for your refrigerator.
