Kirby Heritage II Vacuum\015 I have a Kirby Heritage II vacuum cleaner that was repaired a few months ago. \302\240 The problem was that the carbon brushes had worn down, thus the motor would not operate. \302\240..Now, a few months later, the vacuum was in use when the motor started to die and finally stopped. \302\240I opened up the vacuum and noticed that one of the carbon brushes appeared to be worn again — so I wasn’t getting good conductivity across the motor. \302\240 This appears to be suspect that the new carbon brush would wear down so quickly...What could be wrong with the motor, and is it really worth fixing?..–Clarke\015
How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Brushes being installed incorrectly or the wrong sized brush being fitted. Brushes experiencing damage due to electrical underloading or overloading. Winding faults. Voltage surges to the motor.
A suitable brush can last up to three years and help to extend the service life of other components such as the slip ring; however, unsuitable brushes can lead to drastically increased costs and unnecessary downtime.
Relevant Questions and Answers :
the most relevant questions and answers related to your specific issue
1 – one or both bearings are worn so armature (rotating part) wobbles as it is spinning and cause motor brushes to wear fast. Solution – change bearings too.
2 – Whoever replaced brushes – did not use some brush seating sticks to make cmutator smother and contour brushes to the shape of the comutator (not likely). Solution – appropriately install new set of brushes.
3 – Comutator is so warped that seating sticks do not help anymore – solution – new armature or turn the old armature.
4 – The fact that ONLY ONE brush was worn may mean that there is something wrong with the brush or housing. Maybe it could not move freely within the housing? I think this may be most likely cause it it may be a combination of all 4.Is it worth to fix? Hmm depends how much will it be. If this is 100+ – I’d say get newer Kirby for 300 ad enjoy the tech drive (Heritage does not have tech drive so it is much harder to vacuum with than the newer models)
.(2) Remove the brush assembly by pulling/unlatching it from base on each side.
.(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
.(4) Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen and reassemble.
was vacuuming and rug got caught auto shut off kicked off power to brush. instead of hitting red button to restart brush I disconnected brush to vacuum some hair in Conner. after i reconnected the brush and hit the red button but no power to brush. Light won’t even switch on. Hope you can help
I have several times:
removed the brush and replaced it OK.
pushed the red button by the brush.
pressed the brush power switch.
..Once they release, turn the vacuum over and lift cover of power nozzle at the back. This pulls the front of the cover out of the lip on the “bumper”.
.Once this is done, you’ll need to unscrew the screw at each end of the brush. Lift the brush out and thoroughly clean it, including the ends.
.Check the wiring to make sure they’re connected to the terminals of the motor. Also, check the belt for wear and tear. These belts can last for five years or more, but if it looks bad a good time to replace it is while you have the power head apart.
.When reassembling the vacuum, ensure the belt is fitted properly around the motor shaft and brush.
.Insert the front of the cover first, ensuring the edge fits neatly beneath the lip on the bumper all the way around. It takes a little manipulating to press the back into place. Make sure both tabs click into the locked position. Turn the vacuum over and reinstall screws. Try to rotate brush by hand a few times.
.At this point, plug the vacuum in and turn it on. If the power head doesn’t run, press the reset button. If the power head motor still doesn’t run, it could be due to loose or disconnected wires that lead to the reset switch, a bad reset switch, or even a bad motor. The vacuum needs to be taken to the nearest Aerus Electrolux store for further diagnosis and repair.
