Reconnecting HVAC fan motor, capacitor(s) and booster
5 Attachment(s)
Hello everyone!

I've been a huge fan of the website for quite some time now for my numerous DIY projects around my house. Today, I need to pose a distinct question to the group. I'm trying to connect these items on my central air unit as well as connect the wires from my new fan motor: See picture 1.

However, the new fan motor has 4 wires instead of 3 unlike my old one. See picture 2.

How can I connect my new fan motor to the fan capacitor, the other capacitor and the booster. I have included pictures 3, 4 and 5 to give you a detailed view of my system.

How can I properly connect all three items in picture 1 as well as the new fan motor?

I really appreciate any advice--it's hotter than :furious: in my house right now.

The new fan motor wire colors are: light brown, yellow, black and brown with with stripe.

Fan-black to left side of contactor where the other black wires are. Yellow to the left side of the contactor where the reds are. Two browns to new fan capacitor.

Booster- to herm and C terminals on larger capacitor.

Larger capacitor- that red wire that is spliced to a black goes on C. That should leave one yellow wire that goes to the compressor-hook it to herm terminal
Nothing goes on the fan terminal on that capacitor.

Do what Marty S. Said,

The only thing different I would do is throw away that booster and buy a real a hard start kit. The 5-2-1. That booster is nothing but a piece of junk. Sorry to say it

Thank you guys so much. I hooked everything up according to the advice given and cleaned the unit's coils and it is running a lot better than before.

Thanks again! Not only did you all save me from another uncomfortable night but yall probably saved my marriage. I don't know what it is but I think heat brings the worse out in people. lol

God Bless you all and again thanks a lot.
