I have replace the blower motor on a Coleman eb15b and it has a blue black yellow and red wires and two capacitor wires witch wires do I hook. Up

SOURCE: RV AC, how to wire fan (blower) motor to capacitor.

You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.

1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.

Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.

This should make you a happy camper. Please rate me accordingly and good luck.

Motor Wiring
Old Motor
Brown wire is Start
Yellow wire is run or Power
Black wire is High Speed or Common
The other two taps are speed taps, but you have a single speed application
And high speed is what you need ,that’s why there’s not any wires
on Red and Blue if high speed was to much then you would move the
Black wire to one of the other taps RED low speed or Blue Medinm speed
New Motor
White goes to the Yellow wire from the capacitor
Black goes to the Black wire you took off of high speed on old motor
Of course both Brown wires go to the capacitor and Green to ground
If a capacitor doesn’t discharge it doesn’t mean it’s bad
but the capacitors don’t last as long as they used.
Any time you put in a new motor always replace the capacitor
It will save you a lot of time and grief later on.

There should be a wiring diagram on the side of the new motor.
The brown and the brown w/ white go to the new capacitor you should have bought with the motor.
The black and white go to your L1 & L2 power source. The remaining wires must be capped off.

Testimonial: "Thanks for the info. although a day late it confirmed what a friend had told me also. Didn't see any wiring diagram on the new motor."

SOURCE: Need wiring diagram for installation of an A.O.

These wire colors are the different speeds for the motor. You will have 1 wire going to the heat, 1 wire going to the cool, and 2 wires on the park terminals on the board if available. It will actually tell you the speeds of the colors provided on the motor itself i.e. BLACK=High and so on. Without knowing what model of unit you are working on, it's hard to say where exactly the wires will hook up, but the majority of the time you will have a electrical board inside the furnace and the terminals that I described will be marked. Hope this helps and good luck!

Sounds like the old motor only had 1 speed. You will only need to connect one of the speed wires, probably the Hi-Black. Tape up or put wire nuts on the other 2 speeds. Connect the Hi to the red you have and the yellow to the white. The green should be a ground wire. Look at the label on the motor to verify what I have said. Let me know if it doesn't look like it matches this.
