Greetings. This is my first post, so drinks are on me.
I'm having a couple of issues with my 1HP Sta-Rite Dyna-Glas pump. I recently purchased a 7-year old home with a small pool, my first pool. Anyway, for the past few weeks when trying to start-up from the timer, the motor will hum for a few seconds, then shut off. I assume this is not normal. It will go through this cycle a number of times before finally turning-over. After it finally starts up, the pump runs fine and it has never actually failed to (eventually) start-up. If I try to turn the pump on manually in the morning, it also hums and will not turn over. However, if it's been running all day, I can manually turn the pump off and back on without a problem.
I am able to reach in and spin the impeller. It appears to spin normally (or what I believe to be normally).
My first thought is replace the start capacitor, since it's a relatively cheap and simple task. However, here is where the second issue comes into play: I'm having trouble removing the cover to access the motor/electrical end. It seems to only be attached by two screws and should just slide off, but the darn thing is really stuck on there! I fiddled with it a little (tried prying it off with a screwdriver), etc... but not wanting to damage anything, didn't go much further. Any advice on safely removing the cover? Also, would a failing capacitor produce the sluggish start-up? I friend told me that a capacitor either works or does not -- so perhaps I should be looking elsewhere for the start-up problem.
Thanks in advance.
(yes, I shut off the power at the circuit before doing any of this )
