On another note
While you are repairing the motor, you may want to check your hose. If it is the braided type they often disintegrate from the inside out and gradually start leaking resulting in poor suction and cleaning efficiency. The newer rubber type don’t do that so if you have one of those you should be good. But if it’s braided once you get the motor going again, you might want to check the hose.
To check the hose, open the blower door on the top, and run the vacuum without the hose on covering the suction end with your hand and there should be virtually no air blowing out from the blower port. Then put the hose on, make sure the suction control valve on the hose handle is closed, then cover the suction end of the hose at the handle and check hoe much air is coming out of the blower port end and if it’s a lot, the hose is leaking. Make sure the suction control wheel on the hose Handle is closed when performing this check.
The old braided hoses usually only last 10 to 20 years so you may have already replaced. If it turns out you need a new one used genuine ones are usually available on eBay every now and then and generics are available too But they tend to not be as good and new genuine ones are available from Aerus and Ray Satterwhite can send one.
If you have a sidekick mini power nozzle some of the generic hoses won’t work with it. I recommend a genuine hose because people have complained of issues with the suction control valves not staying shut on the generics as well as the screws stripping out in time and the sidekicks not working. The hose is a heavy use item and so I have found getting the genuine is best especially if the machine is a regular use machine.
If it turns out you need a hose and you wish to try to find a genuine used one on eBay we can tell you what to look for in the pictures. The hose handle should have the round dial for the suction control valve for surre and no switch on the handle to control the power nozzle. Aerus/Electrolux stopped stamping Electrolux on the hose handles after 2003 when the name changed to Aerus so some newer ones may not have that on them which makes it harder to tell the generics from the OEM’s.
