ム/Read (PDF/Epub) Walk In Freezer Wiring Diagrams

Walk in freezers are a popular choice for commercial kitchens, restaurants, and other foodservice businesses. With their larger capacity, they provide plenty of storage space for large amounts of food. However, they also require a thorough understanding of how the wiring diagram works. This guide will help you get a better understanding of the different components and how to wire them up correctly.

Understanding the Components of a Walk in Freezer

When looking at a walk in freezer wiring diagram, it is important to understand the different components that make up the system. The main components are the condenser fan, evaporator, compressor, temperature controller, and the wiring harness. The condenser fan is responsible for blowing cold air into the walk in freezer, while the evaporator is responsible for collecting the hot air and releasing it outside. The compressor is responsible for compressing the hot air and making it cold, while the temperature controller is responsible for controlling the temperature within the freezer.

Wiring a Walk in Freezer

Once you understand the components, wiring a walk in freezer becomes a much simpler process. Start by connecting the wiring harness to the temperature controller and then connect the condenser fan and evaporator to the harness. Finally, connect the compressor to the harness. Make sure all the connections are secure and that the wiring is laid out in an organized fashion. Once everything is connected, it is time to test the system to make sure it is working correctly.

It is important to note that walk in freezers require a dedicated circuit to ensure proper operation. This means that the wiring diagram must be consulted before any work is done on the system. If the wiring is not properly laid out, the system may not function properly, or worse, could potentially be hazardous.


Knowing how to wire a walk in freezer is essential for any commercial kitchen. By understanding the components and following the wiring diagram, you can ensure that your system is up and running smoothly. If you have any questions or concerns, it is always recommended to consult a professional electrician to ensure everything is done correctly.
