Power Unit VX475 Stops

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.]

    Mine is 2 years old, I am guessing this is out of warranty. Will they still replace it?

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!"

    I'm on my 3rd vx475 power unit. The last one was shipped to me new in April 2010 at not charge and I was told to just "throw out" the broken one. Yesterday unit just quit again. Power light is on but no other signs of anything. Had a burnt smell in the garage where the unit is. Called Nutone today and they say they haven't had any prob w/that model recently. There was a prob years ago with that model that had grey side handles but have been replaced with new motors and changed the color handles to black. They are always so accommodating on the phone and have no prob sending out another vac right away. Just seems so crazy that these expensive units are so easily replacable. Not sure why this keeps happening, its been 7years with central vac and I'm going on my 4th unit!!!

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.

Before giving up your troubleshooting, check the motor carefully to determine whether pet hair or some other substance is preventing it from turning freely.

It stopped working while vacuuming. Still getting power, compressor still working but not sucking.

I'm an owner of an LG LuV200R vacuum cleaner. After years of use it started having an overheating issue where the suction motor stopped after only a few minutes use. The brush motor and compressor motor still worked. After cooling down with power off for at least a few minutes suction motor worked again but quickly shut down. Here's how I fixed mine:

First make sure to clean all 3 filters and let dry for 24 hours if cleaned with water (recommend, but compressed air works good too). A clogged HEPA filter could cause overheating. Check all air passages and hoses for blockages. I've always maintained/cleaned my machine so I had to go a little deeper...

On the control board there is a semiconductor which screws to a right angle aluminum heatsink. See attached picture. My screw was slightly loose; loose enough for there to be a tiny gap between the metals so little heat was dissipated from the semiconductor. My infrared thermometer showed 260°F while running. I tightened the screw and running temp went down to 160°F. Once reassembled the vacuum has yet to overheat and shut down. It's a great vacuum so I'm glad it's working again.

To access the control board you need to remove the front facing plastic motor housing located below where the cord is stored. ALWAYS unplug unit before opening. 2 screws face the rear of unit, (now tilt top of vacuum down all the way) 2 screws face the front at the bottom, and 2 more right above HEPA filter (remove HEPA filter). There is a nut behind culprit screw so you may need to remove the control board attached with 2 screws. I recommend using compressed air to clean off control board if dusty, and check for cut/burnt wires. I had a darkened wire which I guided away from control board at reassembly.

A dab of locktite wouldn't be a bad idea on the loose screw/nut. Hope this helps others.

The unit works well for 3~4 minutes and then stops. Wait another 10 minutes to cool down and it works again but the same issue happens again and again. It is a brand new unit. I read the manual for the...

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

Nutone central vac shuts down after a few minutes of use

this is a very common problem.

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.

Good luck,

My central vaccum just stop working last night. It does not turn on at all.

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.

Stops after a few minutes

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

Nutone central vac vx550

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.

Good luck
