I have a Hoover carpet cleaner that is 1 1/2 years old (warranty was for 1 year ) and yesterday my wife was going to clean the carpets. The machine ahs run perfectly in the past. Anyway, she turned it on, pulled the handle back and saw a lot of sparks where the motor sits, and there was a burning smell. She turned it off, unplugged it and awaited till I got home.
Today I put it up on the bench and started taking it apart. Lots of pictures to guide me in putting it back together. Anyway, when I got to the motor, it seemed fine, so I plugged it in and turned it on from a distance. Sure enough, lots of sparks from the carbon brushes contacting the armature. I pulled the brushes (lots of material left) and noticed that they were chipped on the leading edge. The armature surface is scratched and silvery. Not a smooth surface at all.
What could cause this problem? Could it be a manufacturer defect (even after all this time?) Should I inquire on replacing the motor? Is it worth it? I could net get decent photo's of the armature, but I attached some of the brushes.
Any opinions on this, and where to go would be apprecaited. Thanks.
