Something similar used to happen to me. My pump was located outside, and one day I just happened to brush out the space between the metal contacts that come together to turn the pump on. They are housed under the swicth-box-thingy. Turned out ants would crawl in there, and contact couldn't be made. I hope this helps! It's certainly a cheap, easy fix, but something you'd never think about. Good luck. Karen

Your black and white wires go on L1 and L2. It will not matter which wire goes on with line terminal as long as you just put one cord wire on L1 and one on L2. Be sure you properly switch the motor to run on 115V since it will facotry prepped for 230.<br /> <br /> John

There are many different types of motors. you should have a diagram on the inside of the wiring compartment cover. This is a dayton diagram, but I can't be sure it is the same as the motor you have.Notice line terminals remain the same, but that the internal wires change terminals.

Is the obstruction on hte suction side or supply side of the pump?

Either way, you can disconnect the pump, and work from there. If the pump was installed correctly there shgould be unions ( fitting that can be reconnected on the pump suction and supply. If not, you can cut the pipes a few inches from the pump and then shorten the remainder to acomodate the length of the union. Glue these in place follow the instructions on the glue can.

Try using a water hose with the water on from the direction of the pump to the pool. see if this does the job. Leaves should be able to be pulled through by the oumop, I suspect somthing larger. Do you have a strainer on the suction line? Have you checked the pool filter?

I would check the filter first. Why do you think the problem is a clogged line? How do you know the pump is performing? Does it run a Spa, and nbot the pool?
\Good Luck

There is no question here.

Black tracer wire means it has a black stripe down it.http://www.electricmotorwarehouse.com/aosmith/AO_CONNECT.PDF The link should get you AO Smiths wiring diagrams.

CHECK POWER AT THE PUMP, MOTOR BUZZES ? YES CHECK TO SEE IF ROTOR TURNS, YES CLEAN START SWITCH, HAVE CAPACITORS CHECKED , NO ROTOR DOESN'T TURN MOTOR WILL NEED TO BE SERVICED. ROTOR MAY HAVE RUSTED TO STATOR OR LOCKED UP BEARING .. JAY THE POOL PUMP MOTOR REPAIR GUY IN LONGWOOD FL

O.K. MONIKA READ VERY CAREFULLY!!!!
I DON'T REALLY LIKE TO GIVE 220 VOLT WIRING OVER THE INTERNET,LET ALONE THE PHONE,but I have a good feeling that if you all replaced the seal, you have an understanding of what you are dealing with: 1st make sure all power is disconnected,Breakers too(hey I have to say this so don't take it to heart), now the two black wires are 115 volts each, and the white one is ground, now enough said, the wires going from the source, (pool house,pump room), should be one white,one red, and one green, if this is the case the black and white wires, are the ones to hook up your black wires to, it does not matter (which of your black wires) go to either the red one or black coming from the source, and if your white on the motor is your ground it should goe to the green one coming from your source, if you don't already have them,I SUGGEST, you go to home depot,or lowe's and purchase the BLUE "water tight" wire caps, they can and are a "life saver anytime electrical is used around water, they cost some, but isn't a life worth a buck or two more? remember 115 volts can kill you if your around water 220-248volts will really kill you, so please check and double check all that I have told you. make sure everyone is clear,(pet's too), and flip the breaker, and you should be in business, god bless, happy 4th, and please let me know if I can help more

Not as easy as flipping a switch, it requires you to wire the motor differently. It would also draw twice as much amperage(approx 20 amps for a 1 1/2 HP motor) on 110volts.
My suggestion is to wait for the electrician.

Get it rewound/repaired from electrical workshop.

Hello
You have it wired correctly.Do you know what the rpm of the old motor was?Possible this motor is not the same rpm.
Also i dont know what your doing with this motor,pool possibly? Anyway be sure no check valves are stuck and all air is out of system.

When hooking up capacitor on a pump it doesnt really matter which way the wires go. The capacitor is set up in such a way the it supplys power wherever the wires are hooked up. I hope this helps

Hi and welcome to FixYa, I am Kelly

Black is High/ 2, Red is Low /4 and white is L2 / COM (115 VAC connection) Also shown in Diagrm 69 below link as common

Usually on the side of an AO Smith motor there is a nameplate with a diagram of the connections.

different wire, fuses and connection points. What are you trying to do ?

Thank you for posting your question here on Fixya.com.

It could be the capacitor...use a digital multi-meter (DMM), preferably with a capacitor setting, or an analog meter set for Ohms. With an analog, you should see the needle deflect as if testing a closed circuit then it will slowly drop to 0 if the capacitor is good. If it doesn't move or moves and stays to the side showing a closed circuit the capacitor is bad. If you notice a burn hole near the terminals on the end of the capacitor do not bother to test it. If you do not have access to a meter you can try grounding the posts together with a screwdriver to see if they arc although It is not a very reliable test method. Be sure you are holding on to an insulated handle for the tool you use to short the terminals together or you can get a good poke. If you are unsure how best to proceed, take the capacitor to a local electric motor repair shop. Most will test it for free and will sell you the replacement if needed.

It could also be the pump is bound or the motor is failing. It may be a small part such as the capacitor but could also be the starting switch or the winding itself. You will also want to examine the shaft where it passes thru the pump and motor and look for signs of rust from a pump seal leak.

Part of your problem will be the snake has a reversing switch so it is not as simple as just wiring two line leads. I assume you have a DPDT switch for reversing it? If so line goes to the center posts/terminals, motor L1 and L2 go to one end, motor red and black to the other end, and a jumper crisscrosses from end to end allowing the reversing. In essence, what has to happen is in one direction motor L1 and red get power from one line and motor L2 and black from the other; to reverse motor L1 and BLACK get power from one line and motor L2 and RED the other. All of this assumes you are connecting to 115VAC since that is the portion of the diagram you reference. If not, add a comment with what you are connecting to.

it more likley that the pump is not kicking in or the filters to the pump are blocked up,,

Your electric motor needs new bearings in it.. The capacitor gives the pump a kick to get
it going.

Hope this helps.

It sounds to me like there is a hole rusted through the discharge pipe of the pump. If you are able to
look into the cistern with a flash light while the pump is running. You might see water swirling around
the pump. This means the pump is good, but the pipe is bad.
