Shoot. I guess I mess with a more costly form of heat. It might even
pay to see if I can replace the fan motor on this old furnace, which is
a royal pain in the tail.

It shouldn't be that hard to DO, unless it's concealed, too high, etc.
But the leg work to find the motor...

What's wrong with it? Are the windings burnt, or (much more common)
are the bearings just stuck? Insert repair sequence here...

Thanks. This place is wonderful for arcane info about a whole lot of
semi-woodworking related things.

And like a nube, I told my tale of kerosene (and carbon monoxide), but
forgot about the new weather stripping and such I put on the
garage/shop this summer. Went to light it tonight and it struck me...

Now _I've_ got to find an alternate form of heat.

For a garage. With a non-insulted floor. And two wood garage doors.

Ugghh...

It may only be the capacitor. My knees are acting up, so I hate
climbing the pull-down to check the thing out again, but I guess
tomorrow evening, when it cools down, is a good time. I've got to drop
a jointer at a freight company tomorrow a.m. early, get that off my
back (3 to go!). There may be some fun with the capacitor, as the
furnace is at least 20 years old. Worked when I got it 5 years ago.
With the gear I have now, the best way to check the capacitor is to
get the numbers, buy a new one and try it. I did locate my small
multi-meter a couple days ago, right on the beam running down the
center of the attic, next to the furnace.

Anyway, what I get now is a humming noise, which tends to remind me of
a motor with a bad capacitor, but it's been a lot of years since I
fiddled with them, so what do I know. No motor shop here, but maybe one
in Roanoke or L'burg. I do have a nearly new motor out of an old oil
furnace. Wonder if that will fit?
