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

A great way to check if your switch in the hose is bad would be to turn the hose sideways in the inlet. If the unit turns on you most likely need a new switch.

the problem is NOT the motor. Its that the motor is not being cooled. You have to replace the whole top. Call Nutone and its only a $30 part

Unfortunately I don't have a part number for you, but you can call this number 1800.322.2965. Tell them you need a new relay board for your system and they'll be able to help you. They cost around 99$. for anything else you might need, go to www.thinkvacuums.com

Start with this. Unplug the vac to shut off, then disconnect the low voltage wiring at the vac.Plug the vac back in. If the vac still runs you have an internal short on the relay or wiring inside the vac.
If the vac stops then the vac and final wiring is OK and the problem is in the wiring in the house.
Have you removed any inlets for painting or had any renos done or pictures hung. If so undo what you did last. If inlets were disturbed remove them and look for low voltage vac wires touching metal backing plates in the wall or touching the inlet mounting screws.
If you have done a reno or hung pictures you may have pierece the wire for the vac creating a low voltage short which will keep the vac running until removed. I have seen this happen with freshly installed 1/4 round molding along a baseboard
