I ordered all 4 parts and replace them. The vidieo was very helpful except in one area. Installing the larger lower part did not explain or show where the part was supposed to snap in place at. It only showed from a distant view point the person snapping it into place.
The part was a little tricky to get close to installing point. Then I wondered if the product snap over the metal edge, or fit just under it. The best way I could tell was looking at where the old linen was stuck to dryer and went with that.
