Basic Maintenance for Nutone Vacuums

Nutone Circuit Board Replacement

All central vacuums have graduated to an all-in-one control board. They no longer use (and rarely supply) replacement single relays, transformers, and mini breakers. If your Nutone Central Vacuum requires a new relay, transformer, mini breaker, or even a new control board or circuit board, utilize one of these powerful, durable, cost-saving central vacuum circuit boards. The reality is, a central vacuum only needs a motor and one circuit board. Some models have several boards or fuses and multiple components that appear to be essential, but they can usually all be removed and replaced with a single circuit board. It is not very difficult to retrofit a circuit board. An electrician can do it in less than an hour.

To find the circuit board you require, verify the number of motors in your unit and the amperage needs. The most prevalent board replacement for Nutone Vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt, and it may require to be retrofitted. For other voltages and motor, configurations select one of these Durable Generic Circuit Boards made by the industry-leading manufacturer.

Filter Replacement

Much like a regular portable vacuum, the essential maintenance of a Nutone Central Vacuum System is swapping the bag, or, in most cases, emptying the dirt receptacle on the central unit. To do this, extract the base of the unit with a twist or unlatching, dump the debris, place a plastic bag over the bottom, and shake the central-weighted cloth filter. On top emptying models easily open the top and remove the bag. On bottom models lacking a cloth filter, reach up and extract the mesh filter or clean the debris screen. Some models may have a foam filter that can be removed and washed and wholly air-dried.

How a Vacuum Motor Works

All Nutone units used permanently sealed motors in their central collection unit. They need no lubrication or oiling. Routine maintenance for simple residential usage should include checking the motor brushes approximately every five years. While confirming the motor brushes, make sure the center motor shaft is stable and has no play or wobble. If it does, the bearings are wearing out, and the motor will need to be replaced. If the motor brushes are worn to 3/16-inch-long, change the motor brushes.
