Moderator note - Moved from this post: Help. Motor just hums... won't start - Page 2
Just installed a new century 1 HP last night - worked fine when complete.
Came out this morning to find it off even though on timer. Let it cool a bit and it started humming. Pulled it from the pump and found the impeller not moving but able to turn. Made different noises based on turn position.
Then I spun it quickly and it started working.
Of course I put back into place and again it does work just hums.
Does the Cap give it an extra shot of power on start up? Does this sound like the issue?
Like to know if I have any options before buying another motor.
