Do not connect all the speed together. Do you have an RPM of the old and new motor. I think I can help you out if I had that info. Let me know.

I have a sears whole house fan.The replacement motor has 2 poles ,the original has 3.The wire coming to the motor has 3 wires:black,red,white.The fan is 2-speed.This is the right motor.How should the...


The white wire is neutral which is how the current makes a complete path through the fan then back to the panel and operates the motor. the replacement switch you have is a two speed black(high) red (low) switch. If you had 3 speeds before and wish to continue getting all 3 you will need to get a compatible switch. Otherwise eliminate the medium speed (blue) wire and use the switch you have. If the fan has a wire connector system just cut the copper tip even and place a orange cap of wire cap the size that fits tightly to provide good protection.

Im replacing a 2 speed Hayward motor with a AO smith 1 speed motor. I need to no how to wire the 1 speed


to wire a single speed motor you use only the black, white and green wire. there is usually a wiring diagram on the side of the motor to show how this is done.
no wiring diagram then put the black wire on the L1 or H1 post and the white wire to the common and of course the green to ground

I have a 3 speed fan with a red, blue, black an white wires, how are the supposed to be wired with power. the wires go to a little black box that appears to just be wires with no circuit board


The BOX is a GE splicer - with 6 wires - 2 grey power wires, then the red, blue, black, and white from the fan motor. I have the same problem and cannot find another GE SPLICER 3 SPEED SWITCH for the fan. All switches that I have tried have 4 connections.........so a WIRING DIAGRAM would be GREAT!

Can anyone offer any help? I have tried every electrical store in the area!

Thanks

My pool originally had a 2 speed AO Smith pump motor. Several years back it was replaced with an AO Smith single speed motor. I am replacing that motor with a new AO Smith single speed Centurion Switchless...


Is it going to run on 230V then? If so you would normally use red and black. The white wire should be a neutral and the ground wire is obviously ground.

Do you have a meter you can use to confirm the voltage between the wires? If you do you'll want to start with red and white since you seem to think black was not being used before. If the voltage reads 230 and the motor is set up for 230 then attach one wire to L1 and the other to L2...it will not matter which is connected where as long as one is on each terminal. Insulate the black and ground the ground lead to the motor ground screw.

If the voltage is not 230 between those two check between red and black. If that is the 230 then insulate white and put red and black to L1 and L2.

I have a rheem ac. the fan motor quit. the replacement has 2 xtra wires. howm do i hook it up


Hi,
Without knowing what was there and what you are trying to install exactly it is impossible to give a definite answer...
My feeling that you are replacing a single speed motor with a multispeed motor and that the wires are just extra speeds... if so hook up the black wire, white, and browns,and tape of the other colored wires...

Attic fan motor replacement


It sounds like you are replacing a two speed motor with a single speed. Check the side of the old motor and see if it has high and low speed wiring schematics. If so you need to replace with same model number. Good luck!

Trying to install a fan motor for my outside ac unit replacement motor has 5 wires on it. my old on had only 3 driving me nuts


Your old moter had three wires. Common High and brown for capacitor. This one sounds like a two speed. Dont worry Now you have two brown wires for you capacitor instead of one. Tape off brown wire with white strip. Connect other brown to cap. You should have a white or yellow for common wire and black for high. Tape of the other extra wire and wire in like the three wire.

Told motor was bad, replaced motor, new motor does not run


Black to Black, Purple to White and the new motor requires a run capacitor which brown goes to one side of capacitor and brown/white goes to the othe side of the capacitor. This is providing the old motor is a single speed. If the old motor is a two speed you have an incorrect replacement motor.

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.
