about 30 minutes, and then it starts going "Brummm..... Brummm..." I suspect a capacitor failure, as it is annoying, and would have caused notice if it were a "normal" condition. Annoying, though it may be, I can't see how it would cause any harm... unless it presages a total failure. What it isn't is a bearing failure, or lack of lubrication. My fan spins for what seems like half a minute after power is turned off. -Chuck Harris Reginald Beardsley via Groups.Io wrote:
I don't recall mine ever doing that. I'm very sensitive to noise as I investigate anything I can't identify, so I think I would have noticed it.
