Yep, replaced ours 3 times on 2 units. All DIY. Like Grumpy said, they actually have an assembled repair kit for these due to the frequency of breaks; includes the new blade, guard, silicone and mounts x3. I placed the fan mounts on a butter knife and slid them under the unit so I didn't have to loosen the a.c. mounts too. Good directions and an easy fix, good luck!
