New pool pump motor governor keeps tripping under load

New AO Smith motor for pool pump runs correctly with impeller attached on the bench. When installed, it also runs fine until priming is completed and then it keeps sporadically tripping out every second and restarting from the governor switch. I checked rotation, wire leads, and the correct 230 volt setting. Getting frustrated.

READ ALL .. sounds like your power is 120 v, check with meter on L1-L2 . if it says 230-240v the switch might be lose or there is just way too much back pressure OR the impeller is too big for the motor OR the shaft seal is installed wrong, when spinning the impeller by hand "snap of the wrist " it should almost make a full turn.

Try priming in service mode or backwash mode then change over to automode

It sounds like you have 120v available to motor instead of 220v.. Double check your supply voltage to the motor. This arrangement would cause the motor to appear to work on the bench but would not work under a load. hope this helps.

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.

You should be able to see on the tag "RLA" which is running load amps. It should not exceed this amperage. Could the motor be going the wrong direction? If its going the wrong way, that exactly how it would react.

Where I can buy the A.O Smith 3/4 HP pool pump impeller?


You'll need information from the pump that the AOSmith electric motor is attached to in order to get an impeller or any other pump parts. If there is no nameplate for the pump are there numbers on the impeller you need?

My new AO Smith 2HP pool pump won't pump water, just hums


I'm guessing that you replaced the motor that goes to the pump, not the pump itself. You know the motor works just fine. Is the motor rotating in the correct manner(clockwise or counterclockwise) in relation to the rotation of the pump? Have you checked the pump to see if the impeller is working/rotating? Is the motor hooked up to the pump correctly, so that the motor is turning the impeller? Are all connections to the pump tight, so there are no suction leaks? Have you primed the pump and purged it of any air locks?
