I have a 1 hp WhisperFlo pump on my water features( 2 sprays, 3x18" falls), powered by a 1 hp AO Smith motor. It is a switchless.
When I turn it on, there is an extremely loud buzz, then it trips the breaker within a couple seconds. It was so loud, I figured the motor was locked up, but after some more research, I wonder if it could be the start capacitor?
The impeller spins fairly freely by by hand (although it's easier in one direction than the other), so I assume the motor's bearings aren't frozen.
Also, there is no "MFD" number that I can see on the start capacitor. So how can I know which one to order? It is made by Magnetek, and I think it is model number 0102(kinda rusty in spots). there are 3 groups of numbers following that: 60P68-2448, 175663 50-60 Hz, S 1000-AFC.
