Major Appliance & Refrigeration Technology

Appliances are all around us, taking on the heavy work that makes modern life possible. Fixing and maintaining these machines requires knowledge of the science behind them, as well as solid, hands-on experience. This unique program does both. Students first learn the electrical, mechanical, and refrigeration theory of appliances. They then practice diagnostic and repair techniques on the kinds of machines they will encounter in the field. Students are introduced to all aspects of the industry including parts procurement, work order/parts development, and industrial communications. This program is approved as an electrical specialty training school for Appliance Repair (07D) by the Washington State Department of Labor and Industries, Electrical Section.
