Both times it turned out that a poor snake had crawled inside and was killed by the spinning blade. We have also found dead lizards and frogs inside as well. It is a terrible death for the poor animals to be cut into small bits by the spinning fan blade, and it also stinks when the corpses are rotting in the bottom of the A/C. I started looking around and couldn’t find anything specifically to keep critters out of air conditioners.
