In past articles, I’ve talked about how a clean motor is a happy motor. As any service technician knows from experience, contamination is one of the leading causes of premature motor failure.

A lot of mischief can take place away from watchful eyes, and the knowledgeable service technician must be prepared to go beyond treating the most obvious cause of motor problems.
