Re: noisy furnace fan

Yes, you can disconnect the black wire entirely, put a wire nut on the end that goes to the motor and connect the end that goes to the relay to the blue wire, it'll be fine.

As for "Permanently Lubricated," my furnace says that, too, but they must've forgotten to tell the motor manufacturer -- there are lubrication ports on both ends of the motor. I go in there every couple of years and drop in some oil, figuring the motor manufacturer had some reason to put those caps there.
