as for me, i'm better off with a vintage lakewood box fan. i recommend a 3rd gen Lakewood box fan. you can find a good box fan here @

the motors on the newer lakewoods  have a chip so when it blows, it's unrepairable, so a new motor is recommended

Ok, it looks like this post has been here a while, but what the heck. I had the same thing happen now, twice. I recently tore one of them apart to see what was going on inside. and yes, a box fan is a simple piece of electronics. but as with every other piece of electronics out there, there is a fuse inside. A little difficult to find, because you have to take and remove the motor, and remove a piece of heat shrink to get to it. not something the normal consumer will try to get to. but i can not tell you if it is a slow blow fuse, or standard. I can tell you that mine is a 2A fuse.

As the box fan is a simple electronic, I would take the fan apart and check the solder points. If one has broken loose or is cracked, simply re-solder the point. Test it and try again. Another suggestion would be to go to your local hardware store and find some appropriate L-brackets to secure the fan to the sill while still maintaining the ability to remove it and close the window. A little human ingenuity can probably outsmart a cat. ;)
