Customer Question

I have a Pentaior DYNIIN 1 1/2 HP motor (340210) . I just turn off the pump to clean my skimmer and when I went to turn the pump back on it just humms but does not turn on.
Is this from overheating and will letting it sit and cool change this condition?

Welcome. My name is ***** ***** would be glad to assist.

I do not think that model has a capacitor used for starting, check and see if the motor has an oval shaped hump where a capacitor could be mounted to the motor.

If not, can you remove the back section where it wires on the cord, just loosen the bolts and pull the back cover off, making sure wires stay intact etc.

Then look at the center where the shaft is and see if it has a screwdriver slot cut in the shaft that will allow you to turn the motor with a large screwdriver, this should allow you to see if it is totally locked up or not.
If it does turn, you may hear or feel the bearing where it is damaged.

Let me know what is found,
