I made the mistake of having my son change out the run capacitor on my Century B2984 without making him verify the one he was using was matching. High speed now runs but low speed hums and then shuts off, however it does run for a few seconds based on the fact that the fountains are still going. Anyways, he threw the old capacitor out and I need to verify the specs on it. OR should we assume the other start capacitor needs to be replaced?
