Thanks, everyone, for the advice! Ben Sikes, electrician for Dan's Fan City, will be here this morning to install a new fan. Thanks VT, I saw your offer to check for the capacitor after I'd already run up to Dan's. The only overhead ladder work with a fan I would attempt is fixing the pull chain; the thought of pulling the housing off and dealing with wires would be too technical for us!

No caps at Lowes 466a or at Dan's...

Dans Fans would be the last place I would you. Bunch of idiots working there.
