Top 20 AO Smith 1 1/2 HP 115/230V 56C Replacement Motor Questions & Answers

It's a Capacitor, rated/measured in MFD's

Without model info, try this link. Most motor brands follow pretty standard wiring setups. Please rate me if this helps. http://waterheatertimer.org/pdf/AO-Smith-motor-wiring.pdf

A O Smith does not make a Pump, they make motors, so... what pump do you have, so pump rebuild kit can be recommended?

You need to find out what is causing the capacitor to short and "blow up or smoke". Then you will have to replace the capacitor again or the motor will never start up. Sounds like you either have a dead short or you bought a faulty Capacitor. Not uncommon for a 220+ volt Capacitor to be bad right from the factory. I replaced two Capacitors before I had a quality one, but after I replaced it twice I have had no more problems. Make sure to grease the motor through the grease fitting on it. The life of your motor depends on it.

Try posting in the correct area. It is a pump type motor but a I have no clue what a stamley 545 automatic gate is unless it is used to block access down a path or drive.

check motor starter

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
