I'm a new member here at the forum. I need some help in trying to troubleshoot why my pump motor won't start up. It's on a mechanical timer and has been working fine on a daily schedule. Last weekend I noticed that the pump was not running when I went outside. Moved in 3 years ago. No idea how old the pump motor is. However, over two years ago, the capacitor on the outside of the housing was replaced under home warranty.
It is WFE-4 Square Flange Motor. The decal says a Pentair Part O-177450-03. Cross Reference tells me its a 71314. The timer works fine and keeps the correct time. I tried the on/off switch that overrides the timer - nothing; no humming or anything. It does not make any noise at all, nor does it try to start.
I can manually turn the shaft located at the back of the motor which leads me to believe that theres no blockage since it easily turns by hand. I tried changing out the same capacitor - nothing; no humming or anything. BTW, is this one located on the hump of the housing the start or run capacitor?
I'm thinking about opening up the back cover but after reading some threads here, I'm curious....For this motor, is there another capacitor inside the back cover? Is there a centrifugal switch inside the back cover? If yes to either one, what do they look like and approximately where would they be located? How can I tell if it's bad and needs replacement or adjustment?
It's been a few days, I need to get this pump motor working soon or replace it entirely?
