Assuming the motor has the same rating as the one your are replacing, almost all motors have a small schematic on the side.
I am not certain you have a good replacement blower motor due to the color of the wires. If the information on the nameplate data matches, then you are probably safe in going ahead and using it.

(Warning: remove all high voltage to unit before working on unit)

Two of the leads will have to be placed on the same connections as your old motor so trace them back to the control board and install the wire on the same locations. Most blower motor now days have capacitors on them. Make sure you have the replacement capacitor that your blower motor requires. It will say on the schematic on the side of your new motor what the size is. Typically somewhere around 3 to 20 MFD. MFD is short for microfarad. Capacitors are rated in microfarads and in order for the new motor to operate efficiently you must get the manufactures recommended capacitor. After you replace the motor and capacitor, on startup you need to measure the amp draw on the new motor to make sure you will not burn up the new motor. The amp draw maximum will be on the motors nameplate data and when operating, the amperage cannot exceed the nameplate data. If it does it will burn up the windings and stop.
If during any of this sound like something your not confortable performing, please call a competent technician to replace your blower motor. If you burn up the motor, the retailer that sold it to you will not replace it if your not a trained professional.
Hope this helps

SOURCE: I am replacing the a/c

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.

Wire nut or tape the black off. The red is normally 24volt supply power to the t-stat. Blue may or may not be the common. Have a voltmeter?

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.

SOURCE: replaced fan motor for outdoor ac unit old fan has

Hi, the 2 - brown wires are for there own run capacitor they should have sold you. One of the browns will have a white stripe. The new cap has only 2- terminals and you put a brown on each side. The black and yellow wires are both hot which 1- will go to 120 volts on the load or out side of the contactor, and the same with yellow, 120 volts. This gives you 220 volts to run the motor. Look on the new motor and you will have a diagram or on a paper that comes in the box. The old motor used the dual cap to run the compressor to. The green is just a ground wire. Screw it to any metal part or screw. You should be able to put the black and yellow hot wires where the old black, red, or blue were as long as they are 120 volts which I am sure they are. Get a cheap tester when you go get the cap for the new motor, and check the old blk, red, and blue terminals to ground and you should have 120 volts on at least 2 of them. Put the new yellow to 1 and black to another, browns to the new cap and your off and running. Keep me posted. I do this everyday. Please be kind when rating me, thank you.

Iam replacng my home a/c blower motor. My unit hasa red a black and a white wire. My new motor has a black wire a blue wire a red wire and a yellow wire. I need to know which color wire goes to which


On the original motor, red was low speed, black was high speed and white was common. The new motor should either have a diagram on the side of it or within the box for verification, but the black SHOULD also be high speed and the red wire SHOULD be low speed , the blue wire SHOULD be medium and the yellow SHOULD be common. However, you MUST verify those connections on the wiring diagram provided with the new motor before you connect or you will probably let out the MAJIC SMOKE !!! The speed you decide not to utilize can just be taped off and zip tied to the bundle.

You made no comment about two brown wires, and if either motor has two browns, they go to the run capacitor.

on the motor should be a diagram detailing the wires. brown white goes to either side of the capacitor and brown wire to other side of capacitor. hi speed goes to normally open contact on the indoor fan relay and the wire designated common on the motor goes to the other side of power from the relay contacts.

Replaced old Ge 1/2hp fan blower motor w/ emerson motor wire not the same couldnot get to work. motors has blk,blue,red,white/brown, brownw/white strip/furance wires are blk,red,white could some tell me...


I am assuming you still have both motors, if you look on the side they will show you what wires go to what. Your Brown/white should be for the capicator. blk should be blk, blu might be white and red be red. I couldn't really say for certain with out looking at the diagram on the side of the motors. I hope this helped Tim

Replacing blower motor in furnace w/Fasco brand #D727


Some one missed the wiring diagram. I believe its like this:
L1 = Line 1 = (Hot all are same thing)
Black Hi
Blue Med
Red LO
Now usually the black is for AC and connects to a normally Open (NO) contact on the blower relay.
The heater speed (either red or blue) go the the normally Closed (NC) on the blower relay and on one side of this wire or contact on the relay it goes to the heating blower thermostat on the furnace.
The remaining wire (blue or red) you tape off.
L1 also feeds the Run Capacitor on 1 side and the Brown wire feeds the opposite side

The white wire is Neutral and goes to the neutral on the main line.

If this helps you please rate me accordingly and good luck.

Microwave blower motor wiring


I have an OH SUNG from a different model micro and have hooked it up every which-way I could and some how managed NOT to mess it up. I finally realized I needed the 6 microfarad capacitor across the RED and YELLOW. Works like a champ. ****** can move some air btw. I am thinking about thowing this puppy in my PC when I overclock it...

Maybe your VIOLET = BLUE and YELLOW = ORANGE?
