Question about AO Smith 3/4 hp 3450rpm 48Y Frame 115/230 volts Square Flange pool pump replacement motor

1 Answer

AO Smith 3/4 HP pool pump: Turns on, but within 20 seconds shuts off and there's a burning smell. Sounds like the impeller is stopping, but then I don't know what I'm talking about. The sound changes from normal to a quiet hum, then shuts off.

Make sure you are wired correctly. There is different settings if the pump is 110 volt. The motor comes wired for 220 volt

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?

Remove the back of the motor ... you will find there are flats on the shaft. Put your 7/16 or 1/2 open end wrench there and with your other hand, spin off the broken impeller.

the pump must not have any air leaks in the suction side of it,, or it will just **** air and not water,,, water is very heavy you see, however i think its the impeller in the pump thats the problem,,,you should try to put water in the out let of the pump so you fill the pump with water first if its dryed out it may just wear out the impeller before it starts to **** water up, if this still dont work turn off the stop **** and strip out the pump to look at the impeller any wear on it and it will need a new one fitted
i hope this has help you, good luck
