Only hear a "click" when trying to start the system? Does it shut off and start back up in a few minutes? These are common signs of a dead motor which only leaves two options. Replace the motor or the replace unit. If you liked the amount of suction it originally had, then replace the motor. If you'd like stronger suction or if you'd like a cleaner disposal system consider a different unit or alternative brand.
How is a central vacuum maintained? Generally, the only thing required is emptying the main unit. Beyond that there are some upkeep and preventative options given below.
Basic Maintenance for Ultra-Air-Care Vacuum
Motor and Vacuum Maintenance
Much like a regular portable vacuum, the basic maintenance of a Ultra-Air-Care Central Vacuum System is changing the bag, or, in most cases, emptying the dirt receptacle on the main unit. To do this, remove the base of the unit with a twist or by unlatching, then dump the debris. Reach up and remove the mesh filter. To further clean the filter, wash and it thoroughly air dry before installing. Above the mesh filter is a screen that needs to be clear from all debris.
There is nothing to lube or oil in or on the central vacuum system, including the Ultra-Air-Care motor, Ultra-Air-Care vacuum motor unit, or Ultra-Air-Care vacuum cleaner. For the indoor vacuum brush, the fibers that get wrapped around the brush roll of the vacuum cleaner head should be cut out and removed on a regular basis.
Pipe and Hose Maintenance
We recommend cleaning out the hose and piping system at least once per year. The best way to do that is with Tornado Central Vacuum Maintenance Cloths. They do a couple of things. First, they push through the pipes, bringing along stalled out debris. Second, they deodorize the hose, pipes, and unit. Some amazing results can come from this product. The vacuum hose will last longer if it is stored on a hanger, always being detached from the vacuum after each use. See if any of these Storage Items can help your situation (scroll to the bottom of the Accessory Page).
Email Reminders to Empty Vacuum
Sign up for the Free Quarterly Email Reminders to dispose of your central vacuum debris. Let the trash build up can reduce suction, making the unit run hotter and clean less efficiently.
Replacement Motors and Parts for Ultra-Air-Care Vacuums
Self diagnose your system using this Interactive Troubleshooting Guide and Solutions.
Contact a local dealer for service, or consider doing it yourself. Motors on the Ultra-Air-Care vacuum have a few fasteners and wires that need to be unattached, the reattached on the new motor. It should take less than one hour. First, turn off the circuit breaker or unplug the central vacuum unit. Then, access the motor by releasing the outer housing. Use the chart to find the right replacement motor for your Ultra-Air-Care motor model. A motor may have many numbers on it but typically the real motor number starts with 11. Here are detailed Ultra-Air-Care Motor Replacement Instructions
Circuit Board, Relay, Transformer, MiniBreaker
Motor Carbon Brush
Separate transformers, relays, and minibreakers are not available here for Ultra-Air-Care. However, when a circuit board is installed, the most common board replacement for Ultra-Air-Care vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt. The board is strong, yet generic and may need to be retrofitted. There are other Generic Circuit Boards here for units with different voltage and two motors. These robust generic boards are made by the leading industry supplier. An electrician will be able to replace the circuit board, or replace the relay, transformer, and minibreakers with a circuit board quite easily. Print and use the large photograph of the board as the wiring guide.
The Ultra-Air-Care motor has two carbon brushes that wear down and can be replaced before they damage the motor. However, the Ultra-Air-Care motor may go bad for other reasons while the carbon brushes remain fine. Ultra-Air-Care motor brushes can be checked every few years and replaced if the 3/4-inch-long solid carbon is worn down. Definitely replace if one or both are down to 3/16 inch. Type the motor replacement number (not model number) in the search box and the motor brushes will come up along with instructions.
