Central Vacuum Motors
Depending on how much a central vacuum is used, the motor(s) may last decades or just a few years. When a motor goes bad, some of the common signs include an electrical “burning” odor, only a click is heard, and the motor can turn on when the central vacuum unit is bumped. Depending on how old the motor is when it goes bad, you may want to consider only changing the motor brushes.
Motor brushes are much less expensive to change than an entire motor; however, they may not always fix your problem. It may be that the motor ware is so great that the whole motor must be replaced.The most common central vacuum motor brand used is Lamb Ametek. Builtinvacuum.com carries the most popular Lamb motors and some of the lesser popular central vacuum motors as well. Removing and replacing a central vacuum motor is easier than most may think, and shouldn’t take an owner too much time to accomplish.
