A common sense guide to maintaining and repairing all types of cooling and refrigeration units.
I should give it 5 stars for the price. It's a book full of troubleshooting detail, but you have to learn the material to find it. For an example, he mentions to be careful of sulfuric acid contamination in the refrigeration oil under the title of "Compressor Testing". If you flip pages and see only the broad titles you'll miss the good stuff. Most HVAC guys come in on a hot day and just replace the compressor units because the store operator is frantic (after cleaning coils and charging the unit). This "oldie but goodie" book will teach you how to do a continuity test on a hermetically sealed 3 phase motor to see if it's still good. Is it a motor winding insulation leak, winding break, or locked rotor? Explains what can lock up a rotor. Perfect starter book for the maintenance guy who wants to make some side money fixing tossed equipment like Store or Hotel ice machines.

I found the text to be very useful, although it was not the complete and through guide that I was hoping for. That would probably be in the factory shop manual for the central airconditioner that I am attempting to troubleshoot, and those are hard to come by. Ron
