You will have to take the dryer a part to replace the seal.
The goes under locking tab so you will not require sealant.
When you install the new seal it goes on in the clockwise rotation. Start at the 11:00 position and place it under the locking tabs.
The seal will overlap 1 1/4 inches. The coated side which is the lighter of the two colors goes against the tumbler. The seal then looped in a "U" shape so the lighter colored side is against the tumbler back as it is slid in place under the tabs. Bent the tabs back over the seal with a flat bladed screwdriver.
