Check your loacl yellow pages for an electric motor repair shop. They may find it is fixable but could at least tell you if it is salvagable or not. Some even carry replacement motors at costs lower than the pool stores.

Be sure you have connected the motor to the line leads correctly and that the motor is set for the proper line voltage.

A somewhat common problem is that most motors are dual voltage (can be ran on 115 or 230 volt) and come factory set for 230 volts. If you connect it to a 115 volt circuit it will run for a while and then overheat and shut off.

Inside the back case on the motor you'll see a white piece with two copper colored arms that have two silver points that almost touch. If these are rusty I've found that the motor won't turn over
. A quick fix is to take some 600+ grit Aluminum oxide sandpaper and give each of those contact points a brisk sanding to remove any oxidation. This will help the points make a positive contact . Make sure while very obvious that the motor is unplugged first.
If your pump has been leaking water it could be that rust has formed on the inside and is preventing the motor from operating properly. Which requires more aggressive dis-assembly to diagnose.
You can take it to a motor repair shop if the above listed doesn't work.

If there is a capacitor on it, you could replace that. If there is no capacitor the starting switch is probably broken. If you are not used to working with electricity, either have someone qualified work on it or...BE CAREFUL!..God luck...Lee

You could also have a bad starter capacitor, and that's a cheap fix. If you end up getting a new or used pump to replace it try to get the same kind so you can use some of the old pump for parts in the future.
