Cyclonic 14.4 volt DustBuster started loud humming noise?!HELP
Had unit for 6 mos. no problems at all. rather like the vacuum . Recently used it to pic up some sawdust, not very much, and it now hums like a jumbo jet. Need to ask you if theres something i can do to fix. tried cleaning all filters and tapping unit to clean but still really hums? thanks for any help you can give me. Doug
Re: cyclonic 14.4 volt DustBuster started loud humming...
Ours began making a hideous grinding racket and then quit altogether. Upon disassembly, I found a plastic guard protecting the fan that had warped and was preventing the motor from turning at all. Your problem may be related to the same plastic guard. I removed mine and now all is well...I think. If only I could find a replacement for this little guard. Every online parts distributor I've seen will only go as far as selling filters and prefilters.

Check for clogs starting with the air passageway at the bottom....
a piece of TV cable is great for clearing clogs there....check all
hoses...check for dirty filters. If you find no clogs remove the
brush bar and belt and start the vacuum...if the vacuum is no
longer noisy the problem is the bearings at each end of the brush
bar..... WD 40 may fix or you will have to replace. If after all this
the noise persists the the problem is in the motor. (If you use WD 40
make sure it is dry before you vacuum carpet)

sept 30,08 bought dc14 all flloor. After 3 to 4 uses it started making lots of noise when on carpet setting. I examined the roller brush and it was cracked at one end. I returned it Oct 13 ,08 and got another dc 14 all floor. Now this one after 2 uses has the same problem only a larger crack in the brush and a small piece of the brush broke off. Very dissapointed.
First make sure it's not the wall charger - use a meter or a flashlight bulb to test the 15 or so volts that should be on the contacts when the charger is plugged in but the unit is detached.
The next thing is to remove the filters and see how easily the "fan" spins - use a popsickle stick or something that won't break the plastic fan if you can't get your fingers on it. Tight bearings may indicate clogged with dust (or corrosion) or destroyed. Free bearings likely indicate a switch or battery problem (good motor.)
