Hi All,

I have a Starite pump with an AO smith Motor C48K2PA105C5 1 hp. I tried to get it going and it just hums. I figure it rusted up over the winter and I could not reach the impeller to move it along. Does anyone have any tricks to try and save the motor?

Thank you in advance for the help

Can you access the rear of your motor and attempt to spin motor shaft with a 1/2 wrench? This will help identify if your motor is truly seized. Next check your capacitor located on top of motor. Do a thread search for "motor humming"
Someone will be along to give you more information soon.

Hi All,

Thank you for the help, I was worried that I was going to break the spring but your suggestions worked. The pump motor is back in service.
