SOURCE: Replaced Single Speed Pool Pump Motor with 2-Speed Motor

You will need a two speed time clock to really take advantage of real energy efficiency savings. Intermatic makes one that fits in place of the original t104 time clock. You will need to run an additional wire to the pump as well. You will have the ground. Then one common wire that is always hot whether or not you are on high speed or low speed. You could make this a white wire. Then a black wire for your high speed that is energized in high speed and a red wire for the low speed. It is important that the high and low speeds not be energized at the same time, otherwise you will hear a very unpleasant sound coming from the motor, and failure and shortened life of the motor will be realized.

SOURCE: I'm trying to hook up

Yes, it will handle the voltage...

It is odd indeed as a normal AOSmith two-speed motor will have quick-connect AND screw posts for line connection terminals. If you are certain there are only two screws yet the motor is a two-speed then the answer to the first question is yes; you'll need a female quick-connect terminal for your second line connection to the A terminal.

No diagrams here! Do an Internet search using Yahoo or Google, and check for diagrams available manufacturer's website.

Pump won't work on low setting


Most multi-speed motors have have a winding that is connected in as many locations are there are speeds. (two speed - two connection points, etc.). It is possible the the low speed portion of the circuit (the switch, wire, any connections between switch & motor) has failed.

You can check out the switch with a meter to see if there is continuity from the common terminal thru the low speed terminal. Then, continue to the motor itself. The motor should have a wiring diagram on it that describes how to wire for speeds, directions, etc.

It may also be an open low speed winding in the motor. It happens. I strongly caution against testing for power on the tub. It is too easy to suffer an electric shock working around a pool / spa. You should be able to test with an ohm meter and power OFF.

2 speed switch wiring dieagram


The motor will have wiring diagram and voltage on nameplate.
You can re-post question with information that shows on nameplate for more exact information, or keep reading below:
If motor is rated for 240Volts, then it will not work with 120V.
If motor is rated for both 120V and 240V, then either Low voltage or high voltage will work, and one wire will be common, and 1 wire will for 120 and other wire for 240.
If motor is rated 120Volt two speed, then one wire will be neutral, and 1 wire low speed, and other wire high speed. You can connect your wire to either low of high, and cap other wire.
If motor is 240volt two speed, then one wire will be common, and 1 wire low speed, and other wire high speed.
If motor is rated 3-phase, then all three wires are connected to the voltage shown on nameplate.
If motor is rated 3-phase two speed, you may need electrician to wire the motor correctly.

I took the pump out and repaced with a new one. The wiring lugs are different. the old one has White common, black low red High. The new one has no distinction as to what is low or high. How do I hook...


all US motors should have a wiring diagram on the side of the motor unit. The wires going into the pump would hold their same values. I am assuming the previous pump was two speed as well, if not that is your problem.
assuming that they are both two speed reference the common on the pumps motor diagram, and connect the white wire to that terminal.
reference the diagram for correct low speed and connect the black wire to that termial,
repeat for the high speed.
I deal alot with the flo master pumps and they should all be labeled. The most important thing is to get the common correct, switching the other two wires (black and red) incorrectly would simply result in high coming on when low is supposed to and vice versa.

If there really is not a diagram, here is the most typical setup for that motor.

(if you look closely at the terminals on the motor, there are numbers there)
connect the white common to terminal #5
connect the red hot wire to terminal #1
connect the black hot wire to terminal #2
connect the ground
done

Hope this helps.

Have three wires on my air handler blower motor and need to know what order they go in?


Chances are that you have a low speed, high speed, and common lead (wire). One of the three wires should be white, this is your common, or neutral. If you ohm the other two wires, one at a time with the white wire, you can determine which speed is which. The higher the resistance the slower the speed. High speed should go to cool, and low speed should go to heat. Hope this helps.

The side of the motor will have a wiring diagram for how to connect the common, low and high speed leads. Your wire harness should have a white (common), black (usually low), red (usually high) and green (ground) wire. If high and low are backwards, switch the black and red leads.

More often than not red is high and black is low. The white is the common and of course green is ground. If High and low are backwards, swap the red and black.

The new switch is 2 layered - the old one isn't 2 layered


you have to find which wire does what on your switch.Its a three speed fan so you should have three wires that go from the switch to the fan,and one wire that goes from the switch to the hot wire from your house.What you need is a continuity tester.The switches common wire connects to the hot wire from the house.To find this wire you use the continuity tester.as you switch the switch the common wire will be either disconnected from all other wires,or it will be connected one at a time to each of the other wires.only the common wire will be connected to more than one other wire from the switch.If you don't know how to use a continuity tester.it is pretty simple.It has two leads that come from it and when you touch the two wires together the tester lights,or buzzes,or it changes a reading on a display,or all three.depends on what kind you have.what your doing is instead of just touching the leads together your doing it through the switch leads,and hence through the switch.anyway after you find the common wire the other three wires connect to the inputs of the fan.You really want to connect the first wire that connects to the common through the switch to the wire that turns the fan on low then the next wire to the medium then the high.It wont blow up or anything if its in the wrong order,but it wont switch from low to medium to high.
