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
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
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!
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.
Payment Options and Financial Aid
At this time, we can only accept some State and Local grants and limited financial aid options so long as our program meets their requirements. If you qualify for a grant to cover your education through a local office have them contact us to see if our program qualifies. We are registered with the Ohio State Board of Career Colleges and our programs have been approved by them. However, we cannot accept Title IV funding as our programs of instruction do not meet the length requirements.
