Once you know the fundamentals, then refrigerators are the next appliance you want to master. Refrigerators are profitable appliances to work on, and they are the specialty area with the largest demand for knowledge and expertise.
This course covers the principles of operation, common problems, troubleshooting and repair of single and dual evaporator refrigerators, split-phase and inverter-driven compressors. Everything you need to know to work on all the models, old-school and modern.
Note: A pdf or hard copy of the book, Troubleshooting and Repairing Major Appliances, 3rd Edition, by Eric Kleinert is required for this course.
