3 Speed Motor Wiring

I found a fan with a broken control panel (Digital) and I would like to put a manual switch in it (Which I happen to have from another junked fan)

Anyway the fan was a Honeywell and is made of metal

The motor has 7 Wires coming out of it


I applied power to the fan before I took it apart and it works but the LCD/Timer was broken

Anyway I looked at the PCB where the wires went and

Red = High
Yellow = Med
Brown = Low

Gray Goes to a Capacitor
White and black are nutted to a white wire that goes to the Capacitor
The motor is P/N: 11MAM160318 (Which returns no results on Google)


My speed switch has 5 wires
1 2 3 ACH ACN

Is there a way to make my fan work?
I know nothing about wiring multi speed motors but I know how to wire things up safely

Thanks

Where is the seventh wire? You only listed six colors.

Do you have a multimeter?

You have already determined that the red, yellow and brown are the three speed wires so you can ignore them for a while. Do you know where the remaining wires were originally connected to the control panel?

Exactly how is the capacitor wired?

Set your multimeter to low ohms and connect one lead to the ACN wire on the new switch. Connect the other lead to the ACH wire and then step the switch through all of its positions. Note which positions (if any) show continuity. Do this also with the 1,2 and 3 wires noting any position that shows continuity to ACN. Then move the multimeter lead from ACN to ACH and do the same exercise and note which wires and switch positions show continuity to ACH.

Can you post a picture of the motor with the leads and capacitor?

Here are some images of the motor and the capacitor







I don't remember where the other wires went
I also can't find my switch

Please move the wires so that they are not crossing over each other and take the red, yellow and brown completely out of the picture.

Also, I see only one black wire but also a bluish-green wire.

It appears that there is a short "stump" of white wire from that connector that also has a black, white and bluish-green wire. That MAY be the neutral lead but the inclusion of the bluish-green and black is highly suspect.

The black that is connected to the green is also suspect. It seems that using a standardized color code meant nothing to the manufacturer.

I'm sorry, I cannot help you.
