Very easily, I just removed the remainder of the accordion shaped panels from the frames, the slots on the a/c case exterior and in the process, slid out the frames completely from the a/c case exterior. I then completely cleaned the rubber residue from the frames, took the new Shutter Panels, "clicked" the one side of each back into each of the frames and then slid the other side of the Shutter Panels into the slots on the a/c case exterior, while positioning the frames into the slots on the top and bottom of the a/c case exterior. They just slide easily into place and I installed the a/c in the window, as usual and extended the frames with the new Shutter Panels as usual.
VERY VERY EASY FIX! Great site, showing the blow-up diagrams for any part you need to verify. Arrived much quicker than expected and reasonably priced. OUTSTANDING! Would highly recommend for any self-help appliance repair.
It was very easy, just slide the side panel frames out, slide the old shutters out, slide and secure the new ones in, and slide the entire frame back onto the AC unit and it was as good as new.
