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.

You probably have a stuck relay. You can try tapping with medium force next to where the low voltage wires are attached to the unit using the handle end of a hammer. Even if this works it's time to replace the circuit board. Take the unit to a local vacuum repair center for service.

Our exhaust fan is really noisy. Nutone QT 100N-B model. Where can we purchase a new one?


This model has been discontinued but replacement motor assemblies are available. There is no off the shelf model that will fit in the existing housing. If you do not want to replace the housing then the motor assembly is the way to go.
You ca purchase the replacement from either site below:

Nutone Scovill 350 will only turn off if unplugged


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.

Central vac will not turn off


You have a defective internal relay on the vac. Check for warranty coverage as this is a common occurrence on these big box store units.
If beyond warranty the relay should be a straight forward unit, miniature circuit board type plug in device. Find a Broan Nutone service center or take to vac pro shop for parts.
