I have been looking for a diag. for two weeks

[sampson79]

Wait brown is marked I think there is a B written next to a prong... I need the purple

This may help . Still looking.

[Joshdta]

Nope that last link does not have the gp, no luck on finding it either.

I got a camera I am trying to up load pics now

[sampson79]

How do I import pics

Pages 3 & 4 on the link, "IFM" is what you're looking for. Brown connects to one side of the capacitor, yellow & "L2" connect to the other side of the capacitor, and purple connects to "L1".

Thanks for the help man
I guess I am going to have to hire sombody to come and fix this. You guys were great
Thanks again

Oops... "IFM" is "indoor fan motor", not "inducer fan motor". I would bet that, fundamentally, the wire colors represented would be correct in how to wire the motor & capacitor.

Are you sure that is the right diagram, I was not thinking so. That's what I was thinking, indoor fan motor.

[KC13]

It's pretty close, but not exact.

[sampson79]

KC... would yellow attach to the side of the cap. That there is already a yellow running to?
I think I Know where the brown attachs it is marked "B"... It's the purple wire I am asking about

You guys are beating yourselves to death. Make a phone call or send an email. A.O.Smith Electrical Products Company

But you need to know the model of the motor.

They are very receptive.

Quit knocking yourselves out.

We don't count ground. If we can assume a PSC motor, a few reistance checks and your done.

Green ground - (check)


We can figure it out with a few resistance checks.

Think of 3 wires and one is tapped (not quite center), call that point C

The lower resistance to C is neutral
C is L1
The higher resistance goes to the cap
The other side of the cap goes to L1

There may be a reverseable plug on the motor. That changes direction.

DONE!

PS: I think there is an XREF on the AO site too.

I can't find a diagram for your unit, so I am unsure what the function of the "B" terminal is. The yellow motor lead should connect to the capacitor with the "L2" power supply lead - probably yellow. The brown motor lead should connect to the unoccupied capacitor terminal. The "B" terminal may be a controlled/switched line voltage output for the inducer, in which case the purple lead would connect there. If you can provide the complete model #, I may have more success in tracking down a diagram.

[sampson79]

Complete model number for the motor or for the unit

[KC13]

complete model number for the motor or for the unit

The unit will do for now.

Look at page 21 at the drawing. Then look at IDM which is your draft inducer motor. Then look at V10 which is Violet=Purple then to W50 then to CM. Then you will see where the wire goes.

This wiring is for a 3 phase unit BUT all the units use single phase for this part of the wiring.

Always check voltages when connecting and I believe that fan is 230 volt not 23 volt.

That little motor also has a capacitor also so you should have got a new one since they go bad or can cause the motor to fail. The capacitor is a lot cheaper that a new motor so I suggest you replace it also.
