About 25 years ago I installed a little t-stat controlled gable fan
in my little MO bungalow attic. Maybe 12 years later, it was causing
bad static on tv, radio in the room under the gable.

So I installed it in the detached garage in back (for same purpose,
cooling in extreme July, Aug. heat). It's still running.

Now the gable fan I replaced it with (Cool Attic 1500, in service
since '96) ceases to work. I lubed it as best I could. It's getting
elec. power from the tstat. Motor just refuses to turn over. Fan
blades are not locked, turn by hand, a bit tight, 'tho.

I figured it just burnt up 'till I remembered the older one still runs
after 25 years. Why should the newer one go south?

Any ideas? Should I just pull the Cool Attic, take it apart to confirm
motor is burnt up (or whatever)? Or just order a replacement?

Thx,

"Law Without Equity Is No Law At All. It Is A Form Of Jungle Rule."

Many of the newer fans have an over
temperature fuse device in the
motor. It is a fusible link which melts
above a set temperature and also
above a set current. A friend just
called me to discuss the one he just
worked on. There was a little square
device, about 1/4", buried in the
motor windings. It was marked 5A and
130 degrees C. Apparently, a
raccoon had pushed in the protective
screen and stalled the fan blades.
The link opened and the fan stopped
working. I did some googling and
found a manufacturer of the part.

Your problem might, of course, be
different .... maybe.
