A central vacuum motor extends the lifespan of the electrical appliances. If the vacuum cleaner starts to display erratic behavior, then it may be time to change the central vacuum motor. The good thing is that central vacuum motors across different brands of vacuum motors are similar in design and shape and operate roughly the same way.

1. Purchase a New Vacuum Motor

Check the brand and buy the replacement parts from the company. The shop that the vacuum was bought from or the Internet are good places where quality parts can be found. Common brands will include Imperium, VacuMaid, and Beam.

Be careful when buying from Beam companies. There are cunning sellers that disguise themselves as Beam. Always buy vacuum motors from the companies themselves. The same goes for VacuMaid. When ordering online, be sure to check that all parts and accessories as listed in the manual are available.

2. Removing the Cover

Remove the main power source from the motor and remove the cover. Refer to the manual that can teach you how to remove the individual parts.

3. Detaching the Motor

The fasteners will have hex style heads. Depending on which brand, the hex head will vary in size. Loosen and take out the fasteners. The Vacuflo brand will have a larger hex head. If the fasteners prove too hard to remove, use metal lubricant like W-40 to make it easier to unscrew the fasteners. Push down the motor and the motor should be disconnected from the receiving bracket. Separate the motor from the relay control module.

4. Inspecting and Putting in the New Motor

Replace the new motor the same way and hook it to the receiving bracket. The new motor should be attached to the relay. During this time, check the motor. One way to check the motor is by inspecting the brushes. To do this, locate the brushes at the opposite side of the motor body. Check the brushes for any signs of damages.

If damages are indeed found on the brushes, then it’s time to replace them. Be sure to buy the correct parts from the correct manufacturer. The brushes are attached in a spring loaded system. You know the brushes are disconnected from the motor once you see the brushes jump. When reattaching the brushes, be sure that they are all all the way in.

5. Connecting the New Motor

To fully connect the old motor, mounting equipment will be needed. While doing this step, check the motor gasket to see if it in perfect condition. Check the protective screen on the motor gasket for any damages or tears.

6. Test

Once the new motor is installed, test it. Resupply power back to the motor and turn it on. While the unit is running, check the exhaust. A slight gust of air should be felt that shows it is working properly. If there is too much air coming out, check the motor gasket and seal. Be careful of electrocution when inspecting the vacuum motor.
