Check the white wire aside from the capacitor where it connect? If it is connected to L1 then the 3rd wire should be connect to L2, or else opposite.

Replaced a ge condensor fan 3 wire with new dayton the wires are different...old fan has a wire connectort mouted to it orange,black yellow, the new one 2brown 1 with white stripe, purple, black, i have...


the new ge fan requires its own capacitor, the brown and the brown/white go direct to new fan capacitor. black to relay (leg one of power) purple to relay (leg two of power. the compressor will have a wire to the relay and the other to the herm terminal. you now will have nothing to the original capacitor fan terminal.
The new motor will have the diagram showing this. you need the capacitor that goes with the new motor. the grainger guy should have sold that to you with the motor.

I am replacing my old a/c fan motor with a new one. The old motor is an A.O Smith B13400-251 and has black, brown, and a purple wire and was connected to a dual capacitor. The new motor is an A.O Smith...


For one, thank you for posting all the info, it really helps! On your new motor, the white has became your purple, black is black, and your brown/brown and white wires go to each side of the new capacitor, there should only be 2 terminals. You can leave the "Fan" terminal blank on the old capacitor now. Just be sure to attach the new capacitor somewhere secure, they are smaller, but can be a pain. So just to recap:
Black is still black.
White is what purple used to be (Com)
Brown on 1 side of new capacitor
Brown/White on opposite side of new capacitor.

Hope this helps get you to cooler days!

Wiring- Connecting wiring on replaced fan motor


Your new fan motor should have a diagram with it or at least printed on the side of the motor, that will help a lot from your end. As for me, I don't know what unit you have, so I will try to help you with just the basics.

Your old motor probably had 3 wires. One went to the contactor, that is the "Line Voltage", one went to the Common terminal on the old capacitor (COM), that's the other "Line Voltage" wire, and the last one went to the "FAN" terminal on the old capacitor. The reason the old capacitor looks different is because it works for both the compressor and the fan motor (split capacitor). You still need this hooked up for the compressor to work.

The new fan motor.
These vary in brands and wiring so I can not tell you the colors without knowing exactly which motor you have. On the new motor wiring diagram, you should see the "Line Voltage" as described above that 2 of the wires are ran to each other (just on the diagram, not wired together on the unit). This is your power wire that goes to the contactor on the unit, usually black, and your Common wire that runs to the capacitor. You can still run this wire (COM) to the common terminal on the old capacitor since you still have to use the old capacitor for the compressor and the common terminal should still be jumper-ed from the contactor to the (COM) terminal. Then you will probably have 2 wires for the new capacitor, usually Brown and Brown/White. These wires run to each side of the new capacitor and doesn't matter which terminal. Then you will take a new jumper wire from the (COM) terminal on the old capacitor to the terminal on the new capacitor that has your Brown/White lead. Make sure you secure the capacitors inside the unit so not to touch anything surrounding them. Your new motor might also be a "Reversible" motor that has reversing wires also. Again, your new motor diagram can tell you how to hook these up. You have to have it spinning the right way, most of the time it is CCW (counter-clockwise).

I'm sorry I can't be any clearer on this, but without knowing the brands, models, etc, I'm in the dark. If you need any additional help, I would be glad to help! Good luck and hope you get to cooler days!

How do i wire a run capacitor 3 terminals to a 2 terminal run capacitor?


just hook the brown wire to one terminal of your new capacitor and brown/white to the other dont worry about the rest if it leave the wire off the f of the old three wire capacitor you now have two two wire capacitors one feeds compressor the other feeds fan

Heil outside fan motor 3 wire rd/blk/br new dayton motor 4 wire blk /br /purpule /brown with white strip Need help on wiring


Hi, the new motor takes its own capacitor to run it. This is what the 2- brown wires are for, one will have a white stripe. You will need to but a seperate run capacitor for this motor, a 5 uf, 7.5, or what ever it calls for. they should have told you when you bought the motor. It will have to spade connectors on it where the brown wires connect alone. Use the dual capacitor if that is what you have for the other 220 volt wires.Black and purple will be your 2 hot wires.You can connect either one to the old capacitor on the fan terminal and the other to the load side of the contactor, so when the contactor closes it will energize the motor.Or, take both the black and the purple wires and to the load side ( outlet side ) of the contactor, connect one to one side and the other to the other side. The line side is where your 2 hot wires that connect to the contactor from the incoming wires from the electrical box, you want to be on the other end. I would connect the black to the contactor load side and purple to the old capacitor as long as the old wiring is still on it as it has to be fed by a hot wire from the contactor. Each wire, blk, and purple has to have 120 volts to each one and you can get this a couple of ways. The contactor has several terminals that are not used and if you wire them on the outlet side, they will only be energized when the contactor is closed on a call from the stat, very easy to do. You will have to get a coulple of crimp on connectors to put on the ends of the wires, but the brown ones should already have them for this capacitor. Do not try to put the brown wires on the old run capacitor as you will burn out the new motor! Go get the small run cap for these 2 wires for about $10. I know that you can do this wiring change just remember the blk is hot 120, and purple is hot 120, = 240.volts. If you have removed all of the wires from the old capacitor, then use the contactor to connect to. The compressor wires must stay on the old run cap on the hermetic side and this old cap. must be fed by a hot wire from the contactor to the common terminal, that is marked with a C..If you look at the new motor diagram, it will show you also. Please dont forget to rate me as I know you will be kind, and I will check in on you to see how you are doing. Get this capacitor and it will run. This is a must!! Please keep me posted.

Unsure of capacitor terminations for ao smith condensing fan moto


Does the motor data plate say anything about the motor. You can hook up a motor like yours with 3 wires. First use an ohmmeter and check the resistance between the brown/white wire to the black then the yellow wire. The resistance between brown/white and one of the others should be pretty much 0 ohms. If not check between the brown wire and the black and the yellow. Which ever wire has 0 ohms with the brown/white wire is the common leg. You can put a wire nut on the brown/white, it will not be used. Next the brown should be for the start winding and the other wire left over will be the run winding. Then connect the common to L2. L1 will go to the run winding and one side of the capacitor and brown will go to the other side of the capacitor. I hope this isn't too confusing. Let me know if I need to explain it better.

Wires


2 brown wires go to a split capacitor if you have a dual cap which has three terminals marked comp fan com if u have this type of capacitor then the brown wire goes to fan and the brown and white gets capped with a wire nut. whenever replacing a fan motor you should also replace the cap or at least check the capacitance to see if it is still good. you have to check it with a meter that test microfarad.you can get a permanent split capacitor and mount it in there then u use the brown on one side and the brown and white on the other side it only has 2 terminals.

Wiring compressor


The two terminal cap is only for the new fan motor. Connect the compressor wire back where you found it, on the 3 terminal cap. It's the terminal marked, "herm". The "common" terminal on the 3 terminal cap must still be connected to one side of the 220 power at the contactor. One side of the 220 goes to the common on the compressor. The other side of the 220 goes to the run winding on the compressor AND the common terminal on the 3 terminal capacitor.
