I have a Century Electric B855 2hp motor running my Pentair pump. After a big storm 2 weeks ago, I found that the motor wasn't running. It hums and trips the breaker.
I figured the capacitor may have died, but the capacitor looks fine - not bulging at the bottom as it has in the past when it's blown. Ordered the wrong one by mistake (50 mfd instead of 30 mfd) but the motor did the same thing when I connected the 50 mfd capacitor to try it.
I disconnected the motor from the wet end and both the impeller and shaft turn freely. I ordered a new 30 mfd capacitor to see if that will fix it.
Not sure what to do if the new capacitor doesn't fix the problem. I just installed the motor a year ago, and will be bummed if the motor is fried.
Any recommendations would be much appreciated. Some algae has started growing on the sides, so I brushed and added 4 bottles of bleach to my 18K gallon pool. I would really like to solve this before the pool turns all green!
Thanks in advance for any help.
