The program concentrates on understanding designs, recognizing failure patterns and quick replacement techniques. Personally, I never use a text book, rarely refer to a factory manual, rarely call a factory for help, never use a calculator and only use a multi-tester for voltage and resistance measurements. I don't waste time at factory training schools, instead I learn in the field as new designs come out. Experience and a good memory are the only true skills needed. I can supply the experience while you supply the memory.
All students start off slow and gain speed with time, patience and experience.
If they are stumped, they call me. I have worked on many kitchen appliances without a single call back. Ned Goode of Glen Allen, Virginia. Ned sent in photographs of his new service van and a long letter. My exposure to the appliance repair business was non-existent but it seemed to make sense that it would be nice to know how to fix those machines all over my kitchen.
