Broke my roof fan, easy way to fix?

I broke the nice roof fan by stupidly turning it the wrong way Is there an easy way to fix this without taking it apart?

Thanks!

correction the fan is fine, but the vent opener is busted.

is it the crank handle ? if so campingworld has them and worm gear replacements.

Fantastic Fan will send you broken replacement parts for no charge.

Its is a crank handle model, and I turned it to far I don't know that the gears are bad, but just popped out of place If I take the bottum cover off can I adjust these?

Boy do I feel dumb now. That was really easy. For some reason I thought it would be built into the fan unit and impossible to change.
Thanks for the help.

No reason to feel dumb. We've all had situations that seemed much more complicated than what they really were.

For these situations, I consider myself lucky, not dumb!
