From the first page: [I]The motor service manual has been prepared by Westinghouse Laundry Service with a threefold
purpose. First - to explain the motor thoroughly so you will better understand its operation.
Second - to show you how to use this information to diagnose motor failures and third, to make
use of the diagnosis by repairing the inoperative motor rather than replacing it.
Studies indicate that nearly 70% of all laundry equipment fractional HP motor failures can be
repaired (and put back into service in the appliance) on the first call to the customers home.
These same studies show that, more often than not, the inoperative motor is replaced rather than
repaired and that it requires more than one call to perform the job.
This book is not intended to be a one volume course on all fractional horsepower electric
motors. Its intent is to help you to better perform your job as it applies to laundry equipment drive,
pump and fan motors. Failures that occur on laundry equipment motors and which can economically
and profitably be repaired are such parts as terminal boards, end bells, switches, thermoguard and
capacitors (when they are used). There are also a number of adjustments that can be made to get
the motor back into operation.[/I]
