Nutone CV-750 stops during use

\015 Unit shuts off during operation, secondary filter has been cleaned when bag is repplaced. Cleaned it again but no difference. Unit acts like it is overheating. Seems to be getting worse. Is there another filter which could be dirty?\015

Answers :

This was one of Broan/Nu-Tone's beginning attempts at lower-decibel machines. Like so many of their competitors, they choked the motors in dense foam in the head unit and made it too difficult for them to cool. Make sure that you're not blocking or suffocating the ventilation, but don't be surprised... a plethora of makes and models like this one have had to be pulled and discontinued because of the overuse of muffling foam snuffing out good machines before their time.

Chalk it up to a design flaw and start yanking that foam out. The specs on this puppy make it far too good a machine to pass on just becuase of the manufacturer used you as a beta test before they should have relaeased it from proto. If the increase noise irritates you, read up on sound waves, frequencies and subsonics and get creative in how you isolate the parts that bother you. Chances are, though, you'll be just fine.

Lastly, if you can tell me the age of the machine and get me the numbers off the motors I'd love to know more about this situation you're in. You're running dual 2-stage bypass 12.5 amp motors. That puts you roughly in range of a Lamb 472, one of our industry's most hardy motors. If THOSE are what you're running and they're over-heating, you've got a firehazard in your vac that *somebody* never should have put certification on for marketing.
Make very certain that all panels, covers, and seals are in place to assure there are no air leaks into the system. Check all the piping runs to make sure none are broken and that all the ports in each of the rooms is closed. An excess of air reaching the motor will cause this, as will -

The type of motors they use in these things have a life of about 200 hours before they need servicing. And servicing amounts to brush replacement, assuming the motor has not run so much so as to cause damage to the commutator within the motor.

How can I get my DAB radio working again? I have a Sony XDRS100CD with DAB radio. The DAB radio has stopped working although I can still use the CD and get FM radio. The unit has a readout on the front that usually shows the time and this stopped working too, presumably because it got the time via the DAB radio. The unit works from mains and batteries although I have only ever used it on mains.

Brushes stopped The brushes stopped turning while using the cleaner. I removed the brushes to see if the spindle was broken, it wasn't. I then removed the top plastic cover and checked the switch that engages the brushes; it didn't seem to be moving correctly. There's one spring on the switch - should there be two? Or do you think something has broken on the inside? Thanks for any help
