The Fundamentals of Appliance Repair and Refrigeration Online Training Course

fridge_closeThe Master Samurai Tech Academy has created this course especially to meet the needs of authorized servicers for the Sub-Zero Group.

Our emphasis on troubleshooting using schematics and electrical measurements has been a game-changer for many working techs and gets novices off on a strong technological footing.

We begin with all the essential, foundational knowledge an appliance tech needs to have, including the skills to troubleshoot and repair modern computer-controlled appliances.

We then move on to refrigeration. Become well-versed in the principles of operation, common problems, troubleshooting and repair of single and dual evaporator refrigerators, and split-phase and inverter-driven compressors. Improve your troubleshooting abilities by learning how to take a systems approach in your diagnostic work.


As soon as you enroll in the course you can get started. Your tuition fee gives you a year of access to the course.

How long does the course take? Since the course is self-paced, that answer is up to you. Someone working full-time on the course could finish in three to four weeks. Someone who is doing the coursework on evenings and weekends while working full time usually will average three to four months.
