computer board trouble - blinking, chiming, etc. Conversely, the one I keep outside (that came with a house I bought in VB 30 years ago, and is God knows how old) is just humming along. I'm starting to think it will only die when it crumbles from rust. I would kill to have another one of those - I look at Craigs List every day. And as an update, the new fan is in but not running, ugh. I'm going to give it a couple of hours and see if it heals itself, ha . Then I will drink heavily while thinking of a new plan. I might try to find a hot wire and feed the fan directly, and bypass the all knowing board.
