This part was the problem. If you don't hear a click when you press the filter in, this is probably it. It works great now. Pretty easy fix. Repair video was good, however not much room or light to work and make sure you have a screwdriver (or several) that are not too long. The 1/4 inch nut driver as well shouldn't be too long as there is limited room on some of those screws. I also removed the light bulb to get at one of the screws.
