Elevator Troubleshooting & Repair: A Technician’s Certification Study Guide

This comprehensive book advises on what can be expected and details the licenses needed, as well as the codes that must be followed in the U.S.including the National Electrical Code and ASME A17.1. This study guide, aimed at technicians to help prevent them getting in over their heads, begins with "History" to give readers perspective on the industry and advancements in technology through today, plus possible future advancements. Next, types of elevators are detailed, followed by an explanation of how to maintain electric motors (both AC and DC). Variable-frequency drive troubleshooting and diagnostic procedures come next, then advanced motor repair and troubleshooting of complete systems and tools/instruments. Measurement of and ways to improve power quality follow. Finally, there are chapters each on the overall elevator system, motion controller, and connected systems and how they work together.The goal of the work is to cover everything a student or current technician needs to know to perform elevator diagnosis, maintenance, troubleshooting and repair. It also details the knowledge a technician must have to properly service elevators in various situations. Emphasis is placed on safety interlocks and the overall elevator system. The book includes multiple-choice questions for students working toward their elevator mechanic’s licenses. Ten such questions follow each of the 10 chapters, and Appendix A provides answers. Appendix B details electrical laws and equations, and a comprehensive index rounds out the guide.

David writes very well. This book is easy to read and informative. He explains the subject in an accessible and intelligent manner, providing useful background information. I especially enjoyed the chapter on the history of elevators (who new they had been around so long) and the interesting battle of technologies.As well as explaining what can go wrong and how to diagnose and fix, David also explains the fundamentals, leaving someone new to the subject with a rounded knowledge of the topic.The physical format of the book is also really high quality. This is a well made hard-back book, printed on quality paper.

This is an excellent resource for anyone studying for an elevator technician exam or any owner of a business or home with an elevator. The chapter on the history of elevators was fascinating. After each chapter there are study guide questions to help prepare you for an exam. The study guides cover electrical maintenance, motor repair, troubleshooting and more. The pictures and diagrams are helpful and well done.

I like to buy a textbook when I want an overview of a subject, in order to understand better what the pros are doing. We've been having elevator problems in our building, and I wanted to be in a position to understand the repairs that have been tried. Judging from the blurb and reviews, this seemed like a suitable book. But it isn't an introduction to elevators. Rather, it's more like scattered stuff that the author feels an elevator technician should know.

A very helpful guide on elevator repairs. Easy to follow and I like that it includes a history of the elevator industry. Not surprising Archimedes likely developed the first elevator.I also liked the pictures and diagrams that helped to break up the content. I think the study guides will be helpful in preparing for the elevator mechanics license exam.

I found this book to be very readable and easy to understand . I'm not a very tech person but this book takes what can be a complicated subject and turns it into something easily understandable. Nice job. Well written.

I used the information in this book which was very helpful for a project in a house I was selling.

I purchased this book in hopes of learning new/advanced troubleshooting techniques. This book does not provide that, instead it regurgitates ASME 17.1 and NEC 620 requirements for elevators and describes how to use multimeters and oscilloscopes. I sincerely doubt the author has seen the inside of a hoistway.
