Start Here for a Better Career

Our graduates, including many longtime technicians, call our Core Appliance Repair Training course a game-changer for their career. The program is based on a simple principle: you can’t make something work again if you never knew how it worked in the first place.

We start with the fundamentals of electricity and gas, then zoom out to cover the appliance technology that runs on them, technology that’s used by every brand. Rounding out the training is a deep dive into troubleshooting and diagnostics. Our goal is to get you to a place where, anytime you replace a part, you do so not because you hope it’s the source of a problem, but because you know it is.

Is it overkill to know Ohm’s Law or how a compressor system works? No way. Ask any of our students who accepted the challenge of becoming a true appliance repair technician, none question the value of what they learned here. They’re too busy kicking butt and making money.

Great content. Great teaching, I really appreciated the amount of time and thought out in to all of it.
- Blake Martin

I am glad that I took this course. It is an excellent training media. You folks have put together an awesome detailed presentation Thanks so much!
- Jake Burkholder

The course was a great learning experience. From someone who is a novice at the how the appliance works, this is a good intro course (I only look at the outcome not why they are not working or not thinking about how it's supposed to work). Course gives enough detail to answer the how and why noted above. Looking forward to diving in deeper with the other courses.
- joe schmitt

Great course. Very thorough. I think this course does a great job giving you an in depth look at the fundamentals of appliance repair.
- Rod Coty

I had little knowledge in this field. After this course I realized how wrong I was in fixing appliances. My technique was archaic and wasted a lot of time and money. After learning the "Ten Step Trouble Shooting Tango" I no longer needed to TAKE THE ENTIRE UNIT apart in order to find or fix the problem. You can go at your own pace in this class and ask questions when necessary. I have recommended this course to everyone in the field and hope that they will learn as much as I did.
- David

Already having taken a one year HVAC-R course, I still felt that there were gaps in my understanding of the basic electric circuits that make sealed systems work. After doing the research I was led to MST. Now, having completed the core program, combined with my other education, I feel as though I am a much more rounded and capable tech. Looking forward to continuing my learning through the rest of my bundle and with exposure to the best techs on the planet!
- Anthony Harley

This a great course that really helped make sense of the measurements you need to take to troubleshoot appliances as well as what those readings really mean. It provides you with a base knowledge on electricity that really sets you up for success in the rest of the course when it comes to troubleshooting circuits.
- Scott Porazynski

This is a great course recommend to other technicians
- Brandon wardle

I absolutely LOVED this course. I will admit to being a little wary of what an online course could offer. This surprised, impressed and really challenged me. I have spent the last 23 yrs working in aviation and thought I had a pretty solid background in electronics and basic electricity. Boy was I wrong. This course reinforced what I already knew and added a whole new level of information I didn't know I needed. The only thing I have to complain about is not taking the plunge and purchasing the entire bundle. Once again, this course was outstanding. I can't say enough good things about it. I will definitely be taking the rest of your courses. Thank you Team Samurai.
