So I ran my pump all morning and then shut it off for the afternoon. It never came on in the evening. I went out and flipped the switch and it just hummed at me.The motor was hot to the touch. The impeller is free spinning. I tried tapping the motor, resetting the breaker, and cursing at it. I think it’s time to replace it. Anything I should know in this regard? Any recommended place to buy a new one or a super discount coupon that I’m not aware of? My motor is a A.O Smith CAT B129. I’m thinking about replacing it myself as it seems pretty straight forward. Any and all advice is appreciated.
