A Class · Global Sovereign University · Trades
Diagnose the washer, dryer, dishwasher, refrigerator, oven, microwave, disposal, HVAC basics and water heater before the repair estimate arrives. Twelve lessons, one per chapter of the book. Free, no account, nothing to install.
The chapter, broken into the separate ideas you will be asked to use. Read it, or have it read to you.
A bench you can change — break a link, set a meter reading, walk the drain path — and it answers the way the chapter does. Then go put your hands on your own appliance.
A new situation every attempt. Miss one and you are told why that choice fails, and sent back to the exact idea it was testing.
One per chapter, in the book's order. All twelve are open.
Working the lessons is practice, and practice does not earn a certificate. The certificate comes from a separate exam that is graded on our server, so no answer key ever reaches your browser and no score can be reported by the student.
Thirty questions drawn from all twelve lessons; you need 80% to pass. A pass prints a serial-numbered certificate with a link anyone can use to verify it. It says plainly that it records comprehension of the book, and that it is not a trade licence, an industry credential, or a qualification issued by any authority.
Basic Appliance Repair was written by our founder, Dr. Gene A Constant, and donated to the Foundation. Published by Global Sovereign University Press. Read the whole book free, or listen to it, on the reader page. The class is free. The book is how the Foundation pays for it.
