After a few minutes of vacuuming, the power unit stops. Later when the motor has cooled, it will work again. Vacuum lines not clogged and new bag is in unit. Is it possible that there is some excessive heat being generated by motor that triggers a high temp shutdown? Dont see any filter to clean - does it have one inside the unit? When running the motor draws 15.1 amps of current. [Power Unit is only 4 months old.]
Received a call from NuTone Tech Support in respone to my telephone call to them about overheating Power Unit. Apparently my VX475 Power Unit was supposed to have been changed during manufacture with a modification to motor circuit/motor parts. NuTone is shipping to me a new modified VX475 Power Unit via UPS and I am to return the defective one to them. No charge to me for new replacement VX475 Power Unit and no charge to me to ship the one I have back to NuTone. "All is well that ends well!"
Checked and found that motor is definitely overheating for unknown reason. Since power unit is still under warranty, solution was to contact local service company for NuTone power unit and have them come out and fix/replace it free of charge.

the problem may be either the hose or the spout[the area where connect the hose.Start the vacuum and twist the hose around especially near the end that connects to the wand.If it starts and stops it is probably the hose.....please get back to me if this doesn't help...Chris
Hi, I have a Hoover Bagless myself. I also have worked professionally fixing Vacuum Cleaners. There may be some material caught between the roller end and the end bearing or the edge of the roller compartment. This could be causing excessive friction causing the motor to overheat. Like a piece of carpet fabric that wrapped around the end. However, that is not supposed to happen to a vacuum cleaner. If you turn the vacuum cleaner over, exposing the brush, you may find it. And be able to remove. HOWEVER: This is supposed to be a premium Vacuum. It has a very high rating. It certainly is still covered under warranty. I would take my receipt, be safe, and exchange it. I hope this helps, Have a Happy New Year Best, Mark
If the unit is less than 5 years old and you have your bill of sale it will be covered by warranty. Although one of my customers said that there is a recall on the motor in this unit. That is totally unverified. However, if it is still under warranty, contacting broan/nutone will give you the closest warranty depot, or they may just deal with you directly.
I do recommend that both the motor and the PC board inside be changed.
I've gone through 3 vx475 vac in the past 7 yrs. Last one was sent to me in Apr 2010. Just yesterday, once again, my vac just quit. Green power light is on but no other sign of anything. Had a burning smell when vac quit, like motor just fried. Called Nutone again and they can't imagine whats going on but will send out another vac free and was told to throw out old one. They said dust may get into the motor and cause it to quit. These vacs aren't cheap, can't imagine that its so simple to just call up and have a brand new one sent to me. I've asked if they are rebuilt units and was told no. So my advise to you, if you haven't already, is to simply call them up w/model and serial # and they shouldn't give you any prob. good luck.
Its overheating, so the TOC (thermal overload cutout device) is cutting the power to the motor to protect it.
Thats why it works when it has cooled down.
Check for blockages and make sure the filters are clean, if it still happens take to an approved engineer to check the TOC
It's a known problem. I bought my vx550 last year in July and it stopped working this year in May. On for 5 minutes, shut down, can't run for a few hours, runs for another five minutes, etc. I called the Nutone customer service department and they exchanged the unit for a new one, cross shipped, via UPS. Mine was still under warranty though. It has to do with some defective thermostat or controller in the electronics of the vacuum.
