The easiest way to do it is to get a capacitor just for the fan motor (in the motor tag you can read what size cap. you need , maybe 5uf or 7.5 uf) and put the two brown wires on each side of the capacitor and the lines (probably white and black) to the contactor.

IF YOU HAVE TWO CAPACITORS ON THE MOTOR ONE SHOULD BE FOR START AND THE SECOND SHOULD BE FOR RUN. THERE SHOULD BE A SCEMATIC ON THE MOTOR FOR WIRING

What is the yellow wire purpose for a D1026 1/4 blower motor

Can I replace 2 single capacitors on a A/C unit with 1 dual capacitor?


Yes. You will have the terminals HERM, FAN, and COM on the dual capacitor. You will take the wire that comes from the compressor to the Herm terminal, then there is a wire that comes off the contactor to the capacitor(s), that is the Com, you will run it straight from the contactor to the Com terminal. The fan motor will usually have two wires going to the capacitors, finding out which one is which can be difficult sometimes, but there are a few ways to tell. First, it usually has the fan motor wiring diagram on the side of the motor that tells you the colors and what they are. If that is not visible or accessible, then you can see if there are any brown wires. Those are usually the capacitor wires. Since I'm not sure of the model or brand of equipment you are working on, I cant say 100%. You will have up to 4 wires that come into the electrical panel. 3 wire motors are 1 Com, 1 Power. and 1 Cap. 4 wire motors add an extra Capacitor wire which can be eliminated when using a dual capacitor, but you have to know which wire it is. Commonly, there is a Brown wire and a Brown/White wire which you wire nut and insulate the Brown/White and just use the solid Brown. Process of elimination is used to find the Com on the fan. If you have found the capacitor wire, and found the Power wire, obviously the last wire is Com. When it's all over, you should have compressor on Herm, Common from the contactor on Com, Com from Fan on Com, and remaining wire on Fan.

Sorry it's jumbled a little, but without knowing what your working on, I can just give you the general basics. Hope this helps, if you have any questions, feel free to ask.

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.

Replaced fan motor for outdoor ac unit old fan has blue,black,red,and green wires new fan has brown,black,yellow,brown/white and green what goes where


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.

I just purchased an fse1028sf to replace my faulty fan motor. I purchased it from a a/c supply store. My existing fan only had three wires. They were brown, black and purple. Black to: capacitor "c"....


Hi, this is a different wiring diagram then what you have . The 2 brown/wht wires are for the run cap only. Black and white are t-1 and t-2. They sold you a motor that takes its own run capacitor to run it with just both brown wires. Take the diagram from the new motor back along with your original. They will give you the right run cap to go with this motor. Yes, the red wire is power to fire your existing cap and old motor. You will need another cap to run this motor. Don't put the 2 brn/white striped wires on the old cap! They have to be alone on there own run cap. Go back to the parts house and they will show you very fast the wiring diagram and give you the cap. This is a very easy fix when they give you what you need. Keep me posted and ask them to give you what you need to run the motor. A 5 uf run cap perhaps?
Keep me posted.

The two brown wires go to the fans capacitor. The capacitor should always be changed with the fan motor.

It sounds like your unit has a dual capacitor. One side for the fan and the other for the compressor. All you will be doing (After rewiring the compressor wires as they were originally.) is abandoning the fan side of the capacitor, and wiring your new capacitor to the brown and brown with stripe wires. It does not matter which terminals the brown wires go on.

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.
