Would anyone happen to have a wiring diagram of this model? While visiting my Mom in Florida, I replaced the power cord on the vacuum. I discovered that my Dad replaced the fans and possibly the motor in 1978 and made note of it with a marker on the fan. Attached to the motor housing is an electrical device that resembles an ancient capacitor or possibly a pre-historic resistor of some sort. It looks like my Dad may have rewired it because the two leads coming out from the same side of the device are soldered together. (See attached photo). I would appreciate any help you could offer. I can't believe I'm working on a 55-year old vacuum. I was four when Mom got it. And she's 86 now. Sadly, Dad is long gone, so I can't ask him directly.

Thanks in advance,

That's an interference filter -- with old tube radios and televisions, small-appliance motors would cause interference in the reception. You do not need to retain the filter unless you wish to do so for "historical" purposes, or unless you're still firing up tube tvs and radios!

If I'm not mistaken...

hooverbaby's profile picture
that capacitor is wired wrongly; the red should go to one side of the supply and the black to the other. I expect that the yellow is an earth and should be grounded on the machine.

In its current condition, the capacitor will not be doing its job (leads shorted together). However, the motor may still work without interference suppression.

It's possible that the capacitor will have become 'leaky' in some way and it may be necessary to remove or replace it.

Ditch the capacitor

I always ditch the capacitors on old lux's these tend to short out and start popping sparks.the two motor motor leads go to the switch.longer wire go's to the top screw the shorter one go's to the bottom screw as I recall but if I am wrong all you have to do is reverse the leads EASY.

Sometimes I keep them if they are from a machine that has be

Other times, I toss them....but here is a wiring diagram if you want to wire it back in. There should be a point on the switch housing for a screw that is not a contact for the switch. One AC lead will go there, one lead (doesn't matter which one) from the capacitor, and one from the field winding on the motor. The other lead from the motor will be the only lead going to the other terminal on the switch.

The other lead from the capacitor will go to the terminal on the switch that the other AC lead secures.

The yellow lead from the capacitor grounds to the body of the machine at the motor mount.

Hope this helps....

Do some maintaiance

I would go a head and install new motor brushes and clean the fans out with a test tube brush this removes the dust deposits in the fans.

Thanks for your replies and help

I appreciate your help with this guys. Now I know what I'm doing. And Mr. Crevicetool, your schematic is most excellent. I'm an Aero Engineer and couldn't have drawn it any better.

Much obliged,

One further question about this Model E

Does anyone know where to obtain a new or in good condition on/off switch for this vacuum?

I'd suggest trying local vac shops if there are any, asking if they have any old Electrolux parts tucked away. If that doesn't yield any results, then you might watch eBay for another E, hopefully one in grotty condition, that you can use as a "donor" for a new switch.
