Upon initial inspection, I discovered holes in the rubber thing near the front opening. I then did an online search for my make & model & the first one up was Appliance Parts Pros. I clicked on that & quickly found the part along w/ an informative & entertaining video. I appreciated the effort they had put forth to produce that film & decided to look no further & purchase the parts right there & then. It showed up in two days. W/ out the video I wouldn't have known where to start. I watched it one more time & then attacked the project. It was fun & easy. I'd say about as difficult as changing a tire on a bicycle.
