Seems to be a short in the power nozzle (light and beater bar sporadically work) while suction is just fine. How to fix the short?

In order to have suction you need air flow.Essentialy,a vacuum cleaner is trying to create a vacuum the whole time it's on.Just because the beater bar turns doesn't have anything to do with the suction.That is created inside the canister.You have an obstruction in the hose anywhere between the motor and the power brush.

check to make sure power is coming from wall with a voltage meter, if not wiring issue or blown motor or wiring around beater motor

Start simplest always and work back to most difficult... so make sure you have power to the main unit, do you have a cheap voltmeter? If not they're cheap... Second check that connection plug is not stuffed with debris. Point is isolate whether it is the unit or attachment, most likely it's in the connection and repairable by you or used vacuum repair.

Buy a Kenmore for less money

probably a broken belt. part # 38528-033

Even though the brush is spinning, you probably need to replace the beltbecause it is stretched. It is probably slipping on the beater bar.

the drive belt only controls the beater bar if the bar is spinning the belt is fine.
the no suction problem is probably caused by an obstruction in the line , the most common place that this occurs is where the handle pivots from the power head, if the tool hose can not be pulled at this location, remove the cover for the beater bar and you should be able to reach obstruction from there

Hello,

Remove the base plate and beater bar. Clean the suction cavity behind the beater bar. That's where they almost always plug up.

your filter is dead. fit new cyclone filter

I am getting suction to the power mate, but the mate doesn't
work. The belt seem fine, but the light and beater doesen.t
go on. Tried the reset - no result. Thanks
