    Broan Nutone customer service should be able to help, but describe your problem here. disconnect the vac from the household low voltage wiring to test . then advise what is wrong. these vacs have been prone to a failed relay where they run continually after removing the hose from the wall. The relay is a warranty covered item on some and will have markings on the circuit board for reassembly. what are you trying to rewire

I have weak suction in all ports and also the port on the unit itself (for the garage hose). I just removed the filter and it does not appear to be all that dirty. Trying to figure out how to clean it to...


The CV450 has two motors in it. I would guess that either one of the motors has gone bad or one of the motors is off it's gasket within the unit. Overtime the gaskets can wear and the motor looses it's seal. It is not uncommon for a motor in one of these system to fail after about 8-10 years.

Our cv450 wont turn on when plugging into the wall or using the rocker switch on the unit, there is power to the outlet, the unit is 12 years old,any suggestions to further diagnose?


Check the filter. If it's dirty, the motor will overheat, resulting in the machine shutting off.
Rinse thoroughly in warm water, and allow to air dry thoroughly before reinstalling. I recommend having two filters so you have one to use while the other is drying.
Other problems are possible, but generally entail taking the vacuum to a repair shop for diagnosis and repair.

Will not turn off when hose is pulled out of wall


Some units have an on/off switch on the power unit itself. Check to make sure that is not turned on. Unplug your power unit and remove the 2 low voltage wires (not the power cord itself) . The low voltage wires start at the unit and run throught your home and attach to each hose inlet. They are usually attached to the unit by simple wire terminals or wire capped to small wires coming out. Just unlug the terminals or unscrew the wire caps and pull the connections apart. Plug your machine back in. If it still comes on the problem is the relay or circuit board/switch/ relay assembly inside the unit. If it doesn't come on with the low voltage wires unattached then you may have two wires touching somewhere in the low voltage wiring.

I have a Nutone central vacuum model number CV450W that was working great until I recently removed the hose and it now runs continuously until I pull the plug....any suggestions please


Disconnect the thin low voltage wiring between the vac and the rest of the house. If the vac continues to run you have a defective relay in the vac motor housing.
If the vac stops you have a short in the wiring in the house, likely behind an inlet in the wall.
If any inlets have been disturbed for painting or renos lately that would be the first spot to look in the house for a problem. Look for wires behind the inlet valve which are touching against each other or a mounting screw or against a metal mounting plate behind the inlet. Start at the last inlet used. Be careful not to loose the spring under the screws where the wiring attaches to the inlets

Vacuum won't shut off


the relay is most likely the problem, they get burnt and the contacts stay together leaving the unit on. Try www.builtinvacuum.com for parts.

My nutone cv556 wont shut off


It sounds like the relay is bad. This website has a pretty good trouble shooting page.

If the top comes off, it will be by the motor and exhaust. Just replace it with the new one, make sure you don't mix up any wires. Also unplug it from the AC first.
