Central Vacuum Motor Repair

Central vacuum systems are runby a powerful electric motor. When the motor breaks down, there are lower possibilities of repairing them.Nonetheless, you don’t have to replace your motor every time it breaks down.

We have compiled a couple of steps that could help you fix your vacuum motor and keep the vacuum at peak performance.

  1. Check the System Manual

  2. Check for Power

    If the motor shows no sign of life at all, check whether it is receiving power. To achieve this, open the motor housing on your central unit. The way to do this will depend upon the brand and model you have. Frequently, the electric motor can be accessed through the cylinder or an inspection panel for testing.

    If there is power going to the motor, the issue will be in one of two areas: either the carbon brushes are worn, or the armature needs rewinding.

  3. Remove the Motor

    Switch off and isolate the central unit and uninstall the electric motor. The motor housing may be detachable from the central unit, which will make it easier to deal with. There will be a cover for the motor section, which has to be detached. There are various kinds of fasteners used to hold electric motors in place, and you will have to make a visual check to see which are used on your motor. First, release the supply cable from the motor terminals and then remove every fastener.

  4. Check the Motor

    Clean the motor to read any manufacturer information panels that are attached to it. These will give details of the brand and model number of the motor and, possibly, the correct brush model numbers and details of the armature winding.

  5. Check the Brushes

    Carbon brushes are found at opposite sides of the motor body, and the housings cannot be incorrect. There is no typical fitting carbon brushes method, so once again, you will have to do a visual review to learn how to remove them properly.

    The carbon brushes will not be hard to remove, but they will be prepared for them to jump out of the housing because they are spring-loaded. The carbon brush is slightly more than a block of carbon fitted to the end of spring. If the brush is worn, it will be very apparent. Check both brushes since it is possible for one to appear all right.

  6. Purchase and Replace the Brushes

    After the brushes are removed, you can take them to a supplier to purchase the replacement brushes that you require. Fix the brushes into the motor. Wrap the springs to get the fasteners to work.

  7. Change and Test the Motor

    Re-assemble the built-in vacuum unit and examine the motor. Be cautious about assembling the motor while it is unplugged. Once you test the motor, you can plug it in, but be safe and keep your distance in case some of the pieces are not correctly fastened.

  8. The Motor Still Does Not Work

    In case the motor does not work despite the new brushes, the problem lies with the armature (the central spinning core).

    It is possible to get an armature rewound, but it is faster and probably cheaper to buy a new motor.
