Look at the schematic on the inside panel of the cover you removed. It should have the schematic with the wires and colors labeled as to what goes where. The wires are a common, run and start wire. They schematic should identify the wire by color and motor connection by number. You should be able to see the numbers on the motor by the connection. hope this helps.

NEED TO TEST A AO SMITH BOAT MOTOR IN THE SHOP TO BE SURE IT IS RUNNING GOT BLACK, WHITE, RED, AND ORANGE WIRE.. HOW CAN I TEST JUST BE SURE IT WILL RUN


For a 115v motor, all you need is one hot wire and one common wire. The hot is usually black and the common is usually white. You didn't say where these wires are located, in the motor or in the power cord. Be careful, unless you know what you are doing you could be playing "You bet your life." It might be better to take it to a shop and have them test run it for you.

Wiring a 230v ao smith pump : L1 and L2 connection


Hi, assuming you have 4-conductor wire, use the black and red wires for L1 and L2. It doesn't matter which goes to which. If you do not have a red wire, use black and white. The green or bare wire in a 3-wire cable goes to the ground. If you have 4-conductor wire, the ground wire is the one you used for the GFCI on the breaker--usually the white wire. Please let me know if you have more questions, and thanks for using FixYa.

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.

Need to know how to put the wires in the right order on a AO Smith 5.0 56 spa pump red white and black


Red and Black should each be connected to the individual power legs, for 230 V operation. The white wire should be connected to ground.

Breaker keeps tripping when turning on pump.


The red and black wires if ran correctly are the load lines(power). The white is neutral or ground. If its a 1/2 to1-1/2 hp motor connect the red and black wires to terminals #1 and #4. If its 2 hp use #1 and #4. If its 3 hp use #2 and #4. Connect the white wire to the green colored screw. A grounding conductor should always be connected under the green grounding screw, which is located within the terminal compartment of the motor. You can check the breaker for the wire colors, one should be black and the other red. The white wire should be terminated to the neutral/ground bar in the can.

Wiring new motor


The L1 and L2 are the load terminals. Connect the black wires to the L1 and L2 and the green one to the green colored screw.

My GE window AC Model#AEL06LXQ1 Serial#AM311149P I forgot to add my question. The AC is only a year old/young. It is properly installed in a basement window with ample space outside in the window well which is fully open to the air above the window well is only covered with a window mesh type screen which keeps clean & filters out debris only. Last year around this time it was cooling the entire room nicely however displaying e8 error code intermittently which was a problem. GE refused to advise via phone and set an appt. for a tech. to come over. I did some research and reset, unplugged, waited etc. I have a dedicated electrical outlet for the AC as well. I really do not recall what I did but the unit stopped error coding e8 altogether and worked wonderfully for the rest of the hot season. I cancelled the GE tech. Now this year I am having same problem. Unplugging, waiting, changing settings, resetting to default settings, I have tried everything and to no avail. The AC will run for a while with the compressor in check and cool down the apartment but it doesn't last long, approx. 45 minutes, at best with one or 2 times exception where it held cool overnight. I don't know what to do at this point. I am not too tech-savvy. I also am unable to lift this ac out of the window. I've a back injury and though a relatively small unit, it's too heavy. Please advise. I hope you have an easy fix solution. The user manual doesn't even list the error codes! I have spent hours searching youtube videos and haven't found a solution. Hoping it's as simple as manipulation a setting. Thank you.
