After a series of lightning storms my Hayward TriStar pump no longer runs. It hums for awhile, and shuts off -- I was told it's a classic starter capacitor problem. Tried replacing the cap with a new one that had the exact same specs -- didn't fix it. Called a service company that did the same thing -- didn't fix the problem and they are telling me that I need to replace the whole pump motor. Seems like and expensive oversimplified fix. Any suggestions on my next step -- the pool is getting very green.
