I've been reading threads trying to learn what I can but at this point feel like I just need to ask specifically about my situation. I have a pump motor that appears to be going bad. This morning when I walked outside I heard a loud hum type noise coming from the pump, then after about 10 seconds (before I could get to the pump area) it shut off. When I got to the pump, I noticed that the timer was on and power seemed fine (the timer and SWG were both operating) but the pump was completely silent and non-operational. I tried a few basic things like cycling the power at the breaker and checking for loose wires, as well as switching the timer on/off a couple of times. Never got a response so I left the timer turned off.
About 15 minutes later when I went out again to check for a model number, I tried turning on the timer again and it started making the same loud hum noise, but no water flow or other evidence of movement. After about 10-15 seconds I heard a click and it turned off again. Not sure if it hummed again because it'd been turned off for 15 minutes or if that was just a coincidence.
At this point, how should I proceed in determining if I need a new motor (my default suspicion) or an entirely new pump (I can't see any noticeable cracks or problems with the rest of the pump but I suspect it's relatively old - we moved in 2 years ago and I have no idea how long it was installed prior to that). Or how would I know if I'm lucky and only need a new capacitor?
If my assumption that I need a new motor (but not entirely new pump) is correct, this is the result I get when I try to search by the current motor's model number. Magnetek A.O. Smith 1 HP, 56Y Frame, Up-Rate Motor (B2853) - INYOPools.com
Does it look like the correct replacement? And do I need other parts like gaskets or seals beyond just the new motor? I've replaced heat pump blower and outdoor fan motors before, so the idea of replacing a motor isn't inherently scary to me, but I don't know what I don't know when it comes to pump motors. Thanks!
