Replacing bearing whisperflo wf-26 1 1/2 hp motor

might be a bad breaker, test power at motor you should have about 220v on the line 1 and 2 terminals if the motor is set to run on, there is a daigram on the side of the motor for refrance

More than likely, the bearings are going out on the motor. Usually you'll hear a loud screeching sound when this happens. You have 2 choices here. You can either take the pump to a local repair shop and have the bearings replaced, or you can replace the motor and pump seal. By replacing the bearings only, you're not guaranteed that the motor will last much longer. I always recommend replacing the motor and seal that way you'll be trouble-free for another 4-6 years.

Thank you for posting your question here on Fixya.com.

Your pump is for above ground pools and those motors are generally split-phase and do not have a capacitor. There is an internal starting switch mechanism which can fail and when it does the motor will hum/buzz but fail to start. If the switch arms are just worn out of position you can probably fix it. If they are burned up from wear the switch can be replaced but the cost of the part and likelihood other issues with the motor are close behind lead most people to just replace the motor.

You can have the bearings replaced for about $100. It is something that you will have done by a professional. Consult with a local pool store and they should be able to direct you to someone that does that.

If you just bought this then there will be a diagram on the motor nameplate and/or under the terminal cover where you connect the wires. Generally speaking, there are two wires inside the motor that change positions depending on 115 or 230 v connection. If one of the wires is on a post common to one of the line leads, that usually means you have the motor set for 115V. Is that the voltage you are supplying to the motor? If there is no diagram you can make out on the motor, post what brand motor and the motor model number for a diagram.

The pump is probably fine the motor is the problem. If it just hums it might just be the capacitor on top of the motor. Don't know how long it sat there not able to start. Was the motor extremely hot ? If it got too hot may have damaged the motor. Motor is replaceable without replacing the pump head.

Sounds like you have a bad run capacitor and/or start capacitor. Assuming your bearings are good and the motor spins freely, have you noticed any loud noises, i.e humming, etc.? Sometimes capacitors can go bad. You can check the capacitor by removing that "hump" cover on the top of the motor, if it looks "bloated" it's bad. Be very, very care not to touch the electrical contacts due to high voltage stored in the capacitor. If this is a chronic problem, you may be developing a short in the motor windings and will have to eventually replace the motor. Hope this helps
