Can someone show me pictures of how the pedestal fan is wired. In the pictures could you show the Levolier switch and the capacitor. My pedestal fan is a 24" model k60 TB and the Levolier switch info is  Mc Gill MFG. Co
6A 125v Cat. N 450 3A 250v

Hey Zachary,
I was hoping someone would chime in with one which had the switch intact. All of mine have had that double stacker Levolier switch replaced with a 3PDT toggle switch. This is how it works, so hopefully you can figure it out from there.
The motor is a six pole motor with a start winding. On high speed the windings are in parallel, they are in series on low. Three of the winding poles are on one circuit, the other three are another circuit. You should have five wires coming out, it will help to label them.

There should be one common wire coming off the windings. The ohm reading from it to two other wires should be the exact same (around 10 ohms if I remember right). Label these as run windings & the common wire which has the same ohms to the other two label common.

There should be two other wires which if disconnected only have continuity between the two, these are your start windings. One will hook to the capacitor, the other to the line coming in. The other wire coming in will connect to the other side of the capacitor & T off to the run windings.

On High, there is line power attached to the common & the other line power to both run windings. On Low, the common is disconnected & the line power goes to one of the run windings & the other line power goes to the other one.

They are a neat way to run the motor two speed without secondary windings, but they are very complicated to wire.

Mike mirin posted wiring diagrams on this some time ago i'll have to see if i can find them. Stan what about a non capacitor emerson? I have a 1937 leaf blade that has been wired to run on low, i found an nos levolier 450 switch & would like to wire it up to that fan-- any idea? thanks Lawrence

I looked at it but it didn't have a Levolier switch on it

Lawrence they work basically the same, the only major difference is a start switch instead of a capacitor.

How many wires should go to the capacitor and I am get more than 10ohms to find the common wire. Sorry for all the questions I have very little knowledge about electricity. I will post pictures later.

Hey Zachary,
Depending on the motor, sometimes the capacitor will have two wires on one terminal (line wire & wire going to feed windings) & just the start winding on the other terminal. Other times Emerson tied those wires together with a splice cap.

On the ohms, you are looking for the same reading from one wire to the other two. It may be 10 or 20 ohms, but is a fairly low number.

On high do I want all the wires to have power. And I am still having trouble finding the common wire. In the picture I am holding the two wirers that I can figure out which one is the common wire. When I do what you said I get 11 ohms when I take the readings but when I take the readings from the wire with the blue tap to the wire in the picture from the capacitor it get 40 ohms and it get 50 ohms when I do it with with the wire from the capacitor to the other wire in the picture without tap. I did test it how I thought it was supposed to be wired and it tripped a breaker so I definitely wired it wrong.

Zachary, you may want to check each wire to the chassis of the motor with a meter to see if there's any continuity- there should be none. In other words, infinite ohms or the meter might say "OL" . That would test if anything is shorting to the motor core. It would rule out a short tripping your breaker. 

Stan, by chance do you have a wiring diagram to replace the Levolier with the toggle switches? I have 2 of them with broken Levoliers. A while ago Mike Mirin posted some pics of the wiring, but no wiring diagram. That would help those of us with broken Levoliers. 

Thanks!

The fan did ran when I got it but slow because on wire to the capacitor was not connected and when I connected it to the only place open on the switch it didn't start it just hummed.

I'd still check it. Wiggling the wires around may have broken some old insulation.
