Lighting, Light Fixtures, Ceiling and Exhaust Fans - hood vent re wiring (sort of)

O.K. did something kinda dumb, and need some help. I disassembled our vent hood for painting a few months ago and now the lables I had on the wires have come off and I cannot figure out how the motor / fan gets wired up. I don't know much about electrical stuff, I have just some very basic knowledge. The vent hood is a Kenmore. The Model # is kinda worn but It looks to be 33518 KP. It has a three position light (which is still all wired up - I just removed the fan/motor assembly). Here's my best description of the set up. The fan/motor assembly is located in the back of the unit just to the left of where the power comes in. This is through three wires BLK. R. & W. which run through the top of the unit directly into some sort of junction box and then on to the fan switch and light switch at the front of the machine. The wire(2part) from the motor does not reach the switch I remeber it going into that 'junction box where the power wires come in, but if it connects before the switch that seems wrong to my mind, not to mention that there would then only be one of the three (R, BLK,W) wires left. If this makes any sense to you your help would be greatly appreciated. Thanks in advance. Charles.

Welcome to the forums! Difficult to picture what you have done. Any way you could post a picture of the set up and post it on a site such as photobucket.com and copy/paste the IMG code to your reply post? Basically there should be a cable from the wall containing a black, white and bare wire. If in conduit, it should be probably a black, white and green wire. These wires are connected directly to the black and white wire in the junction box on the fan and the bare/green attached to a grounding screw.
Send a pix and let us sort it out.

No Problem, Give me a few mins. and I'll have some photos up.

Hope this works!

O.K. got it on the third try.
As you can see the wire that provides power to the fan / motor goes into that junction box (which is where it was when I disassembled it) but I can't figure out what/where it connects?

Is the fan single speed? Does it have only two wires? How many conections on the fan switch?

The fan switch is a dial so I'm guessing it's variable speed (the dial turns smoothly no clicks) the black and red wire that you see in the picture run to the fan switch. the white (and a lead from the black go to the light switch. So there are only 2 connections on the fan switch. As for the wires to the fan/ motor there is only what is in the pic. -one double wire black cord.

You should have a neutral (white wire) to the fan and the other fan wire to the switch. Is one of the two wires from the fan white? They seem to be black and red. You may have to look on the fan to see if there is an indication of neutral.

If there is a neutral from the fan it is unmarked. The only wire from the fan itslef is a black cord made up of two identical wires. The Black and Red wires that you see (along with the white wire) go from the switches (fan & light) to the power source.(outside of the unit). I can see no other indication of neutral on the fan (what might this look like?)

Sorry but even with the pictures I'm drawing a blank. If no neutral marked then hook one wire to the supply neutral and the other to the switch. Is the incoming cable (Romex) three conductors plus ground? Is one unused?

Thanks Ray for getting a hold of me .,

ChasD,,.

Here what you need to check little more closer I am pretty sure this is right set up but bear with me a second to verify the set up

White conductor that is netural so look at the switch box if you see the light is on netual that is fine leave the white alone in switch box and go to main junction box where you see a white conductor that part you will need to tie together there and one of the conductor from fan motour I know both are black but a giveaway is one of them will be ribbed or rough or marked with inprints .

Ok that part is done now look at the fan speed control and follow that conductor I know one go to black conductor { that one should be at the light switch as well }and the other one should be red conductor that you will tie the motor lead at there.

If still haveing issue let us know one of us can make a drawing so you can follow it pretty easy

Merci,Marc

Nope, no trouble. That is it exactly. The Black wire coming into the unit is hot. I takes the power to both the fan and the light. The white is the neutral, as you say, and it does, indeed, go to the light. I was mistaken in thinking that the red wire was coming into the unit, what it does, in fact, is it connects from the fan switch to than motor. So one end of the wire from the fan motor connects to the red wire (from the switch), the other end connects to the neutral (White), The Black wire connects to the Hot from the house, the ground goes to the chassis, and the neutral from the house goes to the White & Motor connection.
Thanks alot guys now it all makes sense. Now its on to screw up something else!:)

Now its on to screw up something else! But that is the best way to learn.:)

That is good to let us know how it come out.

Merci,Marc
