I have an Electrolux pn2 that the brush roll starts out normal when I power it on on but after time slows down. Sounds like the motor is switching to a lower gear or something. The motor does not sound like it is running at full cycle. Does anyone know what could be happening? Is the motor going bad? Is the belt too tight? Love this cite! Appreciate this community!!! Thanks, Richard.

Perhaps a silly question, I am not top guru here, but does the same thing happen with the belt off? Any chance the bearings in the brushroll are bad and not the motor?

It sounds like the motor is starting to go bad, when it slows down toes the hood get very hot and do you smell a slight burning smell? PN2's and PN4's were notorious for bad motors. Also, if you look at the color of the field wires, they should be a reddish brown color, when they get old they start to turn black. Motors are easy to replace and are not very expensive, good luck.

I will check both recommendations. Any ideas where I can get a new motor?

Thanks!!!

Your motor may need to be cleaned, they can be taken apart, a lot of times they just need to be cleaned and the bushings slightly lubed. It's a good idea to clean and lube the brush roll bushings as well as that brushroll needs to be turning freely. With a little bit of service and cleaning it'll a lot of times make your power head run like new.

ill 2nd nathan on this one. out of all the powerheads i own electrolux (especially the consolidated foods owned models like the 1205/ golden j) had sleeve bearings that werent very honed from the factory and require frequent oiling to keep running at normal speed.

there is two sleeve bearings in the pn motor (one at each end) and one at each end of the brush roll. oil these with 0/20 weight oil every 6 months and youll be fine. longer than that and the bearings friction with the armature shaft in the pn motor and brushroll shafts will get hot and bind. ive never seen the sieze due to lack of oiling, but they will ger increidbly hot, melt belts and slow the whole thing down.

working on small motors, I found a precision oiler filled with light weight synthetic motor oil works best. Sewing machine oil and 3 in 1 oil is a waste of money. The oiler I purchased comes with various size tips as well.

It is much easier to apply just a small drop with the syringe.

A nod to a great company ..

Thanks for all of the info. I will try to lubricate the brush roll bushings if I can figure out what they look like. Perhaps I can lubricare anything that moves and figure out through process of elimination.
