Does anyone have the wiring diagram for a Carrier condenser fan motor and capasiter? Model # 38EBO30300. Thanks.

I don't have the diagram but I can tell what you need to do.

First I need to know if you bought a new motor and a new capacitor.
Since you are not online for me to find out I am giving you a general piece of advice.

The new motor will have two brown wires, and a black wire, and a white wire and a ground wire, it may have more but these ae the one that you are to be concerned with.

Disconnect all the wires going to the motor, watching to see where the Black wire and the white wire are connected. The black wire and the white wire of the new motor will go back in to the same places. Now the new capacitor will be added to the system, do not do away with the original capacitor, it is still needed to run the compressor. Connect the brown wire to on post on the capacitor and the brown and white to the other side of the capacitor.

Now if you are going to try to use the old capacitor, which is OK if it is the right uf and voltage for the motor you bought. And the capacitor is a duel capacitor which has three poles, here is the way to connect the motor wires. The Brown wire goes to the post marked "fan" The white wire goes to the post marked "com" or just "C" The Black wire goes to the contactor. It will connect to the post on the contactor that does not nave a white or yellow wire connected to it. The brown wire with the white on it can be taped up as well as any other wires coming from the motor except the green which needs to be connected to the unit housing some where.

The wire diagram should be on the side of the motor along with RPM,voltage and what size run capacitor its rated for.

I need the cap wiring diagram they changed from one cap with three connections h c m to a dual run capacitor that has two common posts with four terminal each and a separate cap with two posts of two connections. The wiring diagram shows two caps a dual run with three post and a start cap.
Any help would be great Thanks
