I have a kitchen exhaust fan that's in a hood above the
stove. It's attached to an exhaust pipe that is supposed
to take the air up out of the house through the roof. I
took the fan/hood down so that I could paint around it. I
paid close attention to how it was hooked up, and I know
I've hooked it back up correctly.
The problem is that the fan is not turning the right way.
It's turning to blow air down instead of up the exhaust pipe.
It is important that I mention at this point that I
didn't notice which way it was turning before I removed
it. I assumed it was sucking the air up and out of the
house! I guess I could be wrong.
Can anyone tell me if there's a "quick fix" for getting
the fan turning in the opposite direction? Or a slow
fix? Any fix?
Thanks in advance,

There are only two things I can think of. The fan is mounted upside
down or it is really working right.
Your message sounds like the first, even thought I have never heard of
one like this. If you based your view that it is running the wrong way on
feeling air coming out of it, that could be because some units do vent some
of the exhaust down to create a kind of curtain of air to help with the
efficiency of the unit. My new one does that and it does seem to help.
I know of no way that any residential exhaust fan motor could run
backwards due to failure or bad wiring.
My guess is the fan was initially installed incorrectly.
It it is a fan blade type fan, take an allen wrench and
remove the fan blade. Then reattach the fan blade
upside down. If it a roller type fan, I have no suggestion.
I suggest that installing a fan upside down will have as much effect as
typing the letter "O" upside down, or the letter "S" upside down. You
obviously havn't tried it!
Needs either a different fan blade, or to take the motor apart and put the
armature in the other way. It's not something I want to teach over the net!

Swapping the blade will have no effect. However turning the motor
If present mounting is fan-end up, then change to fan-end down, or
If, perchance, motor shaft shows on both ends of motor, you may need
to move blade to other end of shaft to accommodate turning the motor
over, and still fit the shroud.
