Burning smell and power dogs down

SOURCE: stopped running

orecks have a plastic fan inside and everything you pick up hits it, sometimes things can get stuck in there or break the fan locking up the motor. With the machine off, poke around where the dirt goes into the motor, behind the roller and see if you can pull anything out.

this sounds like the motor went out

SOURCE: brush froze up and keeps breaking belts

I had the same problem but I found that I had replaced belt incorrectly. After placing one end of belt around pully, it has to be run behind the "belt disengager" which looks like a 1/2" wide metal tab just past pulley. After placing belt correctly I had no more belt, burning smell or brush problems.

I just fixed mine. It took me all of 10 minutes. Pull the brush out. Stand the brush on end on the edge of your study work bench/table top. while holding the brush vertical( on end) take a small phillips screwdriver and tap using a hammer on the metal pin you see in the middle of the brush. Keep tamping and the whole assembly will come apart. What you will have then is a long metal shaft, 2 bearings(they are acutally skateboard wheel bearings same number same make). Clean the gobbed up hair with a razor blade and then reassemble by tapping back together. The bearing wont be worn out because they are way too tough for a vaccum. We used ride down hills on them! a ten minute fix wow and you wont have to drive to vacuum shop and spend $$ and time

If you have animals get rid of the dyson and go to a vacuum that has a metal brushroll and better airflow. There is no fix on the dyson they just are not good on hair of any kind.
