Question about AO Smith Pool Pump Motor Hayward Swimming Pool Pump Full Rated Motor / Cen

1 Answer

I am using an AO Smith motor on a Hayward pump to run my pond. It is about 4 years old now. Most recently, in the hot weather (90+F in the Northeast) the pump just shut off as I was watching the waterfalls. I cehcked the electirc supply and found no problems. I left it unplugged to go out, and 4 hours later when I came home I plugged it in and it restarted. That was 2 days ago. Today I was told that it stopped again. It is still plugged in, and I will see if it restarted itself when I get home from work. Is there some type of overheat or overload which shuts it off. Will this restart the motor itself? Does this mean that the motor is going? I noted the motor was in full sun the first time it stopped, and it was pretty hot to the touch, but no hotter than my pool motor which was also running at the time. Thanks, Mike.

Pump is protected with a thermo switch made inside the motor to shut it off if it gets to hot check for oil ports at the bearings if it dose not have them maybe try adding a ball valve and turning down the flow some to create slower flow and higher pressure

I have a Hayward in ground pool pump with an AO Smith model# k48m2n111. It's 10 years old now but yesterday it stopped working and just whines real loud when i start it . Could it be a quick fix? Is it...

Hayward pumps are poor quality. You're lucky to get ten years. In 4 years I've needed the motor replaced twice and the pump repaired. The motor is starting to whine again. Just a matter of time before it fails. Do yourself a favor and stay away from Hayward.

Why is new ao smith pump getting hot

Most motors are warm to hot when running.
Is it getting so hot that the thermal overload is turning it off? If so the pump should restart once it cools down.
If this is a new motor on an old pump (replacement) it is likely to be:
1.) Incorrect or loose wire connections.
2.) Low voltage supply (frequently caused by undersized wire).
3.) Lack of fresh air supply to motor due to clogged vents.
4.) Incorrect amperage of replacement motor.

A.O. Smith c48k2pa105c5 pool pump motor was running fine for 3 weeks. The other day it shut off cause of the thermal switch. Well now when I turn it on it works fien for a couple minutes then it shuts off...

If you mean that this motor is only 3 weeks old, and this is happening, return the motor.

If its an old motor and this is happening, purchase a new one. Even if you had a technician come out to look at the motor, chances are it would cost more than the motor itself.

Largest causes of thermal overload are.

-incorrect wiring
-wiring to wrong voltage
-incorrect wiring size
-bad motor windings
-bad rear end bearings.

Hayward Swimming PoPump is 4 years old - when I opened pool, pump

it you've inspected all the wiring for possible shorts, the most likely problem is that the motor has developed a short in the windings. You may have to replace the motor. First check for loose connections and make sure the wiring going to the pump is good. Also, check the start capacitor, should be under the hump or under the end cover on the motor. If it's bloated or leaking, it's bad.
Most likely the winding have a direct short.
