Advanced Refrigeration Two Week Course

The two-week course is a more in-depth course covering advanced skills on your average residential refrigerator all the way to the expensive built-ins and r600a/lokring. This class is geared towards a seasoned tech who has been in the field and is looking to enhance their skills with the built-in units and R600a training.

Our three-week course is geared toward a technician looking to grasp the fundamentals of diagnosing and repair of 134a systems.

What the Course Covers

The two week course covers the principles of refrigerator repair. This includes:
  • Defrost System Theory, Repair, and Diagnostics
  • Sealed System Theory, Repair, and Diagnostics
  • Ice Maker Operation, Repair, and Diagnostics
  • Dual Evaporators in Domestic Refrigerators
  • Lokring Hands-on Lab
  • R600a Theory and Repair
  • Built-In Refrigeration
  • Sealed System Olympics

Defrost System Theory

We teach the core components involved in defrost systems across all brands and discuss common issues that can cause a refrigerator to stop cooling. This includes understanding the differences between a defrost issue and a sealed system issue.

We will show the student how to use their voltmeter to test many of the components found in the defrost system. Along with understanding the basics of how to read a wiring diagram for a refrigerator.

Appliance Electrical Theory

Before we start with any appliances though, we need to make sure each student knows how to use an analog and digital voltmeter. We also need to ensure the student knows how to determine if an outlet is shorted or in an open state. Refrigeration appliances, especially with all the different electronics found inside, will not function correctly if there is an issue with an outlet. Our staff will walk you through how to safely check various designs to ensure you are providing the most accurate diagnosis for your customers.


Sealed System Theory

The student will learn how a sealed system works in a number of different ways to encourage the student to understand the entire process.

We start out discussing the flow of electricity to the compressor and how to check for issues with different types of relays and capacitors.

Each student will get a torch in hand and go through brazing and soldering exercises. We also have integrated Lokring into this exercise as an additional option. Then we follow up with each student conducting their own sealed system repair in our refrigeration lab. We also discuss our own techniques for diagnosing a sealed system issue to ensure the most accurate diagnosis.

Dual Evaporator Theory

As a class, we will also dive into dual evaporator designs and discuss what makes them different than a single evaporator along with discussing the additional components involved.



Tuition includes a stay at Fred’s Flats which is within walking distance of the academy. Each flat is shared with another student but they will have access to their own kitchen and laundry. Each student will get their own private bedroom. This is a great learning environment and a great way to make new friends and connections in this industry. You will eat, breath, sleep appliance repair while you are here.

Built-In Refrigeration

In our second week of class, students will get exposed to various built-in refrigeration designs and the opportunity to replace a component using Lokring.  Students will learn what will differentiate a built-in unit vs a free standing unit.  Our team will break down how to diagnose and repair common problems with built-in refrigeration including brands like Sub-Zero, Dacor, Kitchenaid, and more!

R600a Refrigerant

What is R600a? How does it compare to the standard R134a refrigerant?  Our team will break down the differences between both.  Students will learn how to identify and repair R600a refrigerators.  Students will get to learn proper repair techniques involving the use of Lokring and R600a with interactive hands-on class activities.
