I posted a thread on here yesterday about a problem with my pump motor. When I opened my pool this year, my pump wouldn't start because the shaft was seized. We just bought the house in September. The outlet for waste from the multiport valve is situated directly above the back of the pump motor and it drips. Over time, it looks like the dripping has caused significant corrosion to the pump motor. I took everything apart at the beginning of the season, got the shaft turning, and put everything back together.
The corrosion was so bad that the back cover of the motor had a hole in it. In order to try to keep water out, I put duct tape around the back of the motor, where the cover meets the motor housing. In retrospect, I think this may have been a bad idea because instead of keeping water out, I think it actually kept water in.
Yesterday (following 24 hours of steady rain), I noticed my pump wasn't on. When I went out back, I noticed the breaker was tripped. I reset the breaker and tried to turn it on, but instead of coming on, I heard a loud pop and the breaker tripped again. I did this one more time before shutting everything down and going to work.
Last night, I got home from work and took everything apart. Before I did that though, I tried to turn it on and I didn't get a pop and the breaker didn't trip, but the motor just hummed rather than starting. Upon taking everything apart, it looks like moisture got in the back cover and caused a short in the wiring. I think the moister also caused corrosion on the main contact points that is causing the humming. I cleaned everything up and I think the motor is okay, but I definitely need new parts, as depicted in the picture attached.
Does anyone know where I can get these parts? Also, does anyone know where I can get a new back cover? BTW, its an A.O. Smith Corp. Motor and the model number is UST 1152.
