How to replace central vacuum motor?

Folks, don’t worry! The following article offers tips and tricks to simplify the central vacuum motor replacement process and walks you through each step-in detail. This task may take an hour or less to complete.

To Make A Replacement Motor, You Will Need:

  • Replacement motor
  • Screwdriver
  • Wire nuts
  • Socket set
  • Pliers
  • Wire strippers

1.Purchasing A New Vacuum Motor

If quality is important to you, you should purchase replacement parts directly from the manufacturer. You can purchase quality parts from the original retailer or on the Internet. There are a variety of brands to choose from, such as Imperium, VacuMaid, and Beam.

2.Disconnect The Power Source And Remove The Cover

Please turn off the house circuit breaker or unplug the vacuum unit’s cord from the wall so that no power is going to it.

There are usually one to three screws on the side of a motor on the bottom. To reach the motor, remove the top cover of the unit. Also, you should remove the components following your manual.

3.Motor Detachment

Motors have two or three wires that connect to relays, mini breakers, or other wires. Disconnect the motor wire from these devices. There may be a difference in the connection between the new and old motors.

Depending on the case, it might be easier to keep the motor attached to the component and cut the wire. After this, you can tie a wire nut to the new wire from the new motor.

A motor is typically held down with two to three bolts, screws, or springs. Additionally, there is a gasket on every motor. You can reuse a thick gasket that separates from the motor; if it is thick, a replacement is probably unavailable. We suggest that buy a new gasket if yours is thin.

Different brands have different sizes of hex heads. Take the fasteners out carefully and loosen them. (Vacuflo will come with a larger hex head.) You can use a metal lubricant like W-40 to make the fasteners easier to unscrew if the screws are too difficult to remove.

4.Install The New Motor

In order to maintain a seal, the new motor must sit on a gasket. Then mount the motor and attach the gasket to it. Install the new motor carefully without overtightening it. Remove anything attached to the exhaust horn if the motor has one. In case the motor coupling cannot be salvaged, buy another one.

Hook the new motor to the bracket in the same manner. Ensure that the motor is connected to the relay. In the meantime, make sure the motor is functioning properly.

You can inspect the brushes to determine if the motor is working. You will find the brushes on the opposite side of the motor body. Make sure that the brushes appear to be in good condition.

If damage is discovered on the brushes, then it is time to replace them. Make sure you get the right parts from the right manufacturer. A spring-loaded system is used to attach the brushes. As soon as the brushes jump, you know the motor is disconnected. Reattach the brushes and make sure they are all inserted well.

5.Connecting The New Motor

Generally, vacuum motors are neutral-polarized, which means you can connect the white wire to either the black wire or the white wire (depending on the old or new motor). As a result, if the motor wires are switched, nothing will go wrong. It would be best if you reconnected the motor wires as it is.

If you do not have the proper ends, splice the new wires together with a wire nut. You may often find a green ground wire on the vacuum tank metal or some motors.

To ensure the motor gasket is in perfect condition, check it while performing this step. Make sure the motor gasket does not have any tears or damage to the protective screen.

6.How To Test A Central Vacuum Motor

You should test the motor once it’s been installed. Put everything back together, and plug the motor into power. You can test it by switching on and off the unit. Activate the motor by resupplying power.

During operation, check the exhaust. Whenever it is working properly, you can feel a slight breeze. You probably need to check your motor seal and gasket if exhaust air is excessive. Examine the vacuum motor carefully to prevent electrocution.

Make sure the vacuum is properly and securely mounted on the wall after it has been taken apart. It is not important which wire is connected to which connection, just that the low voltage wire is connected properly.
