Took off the back of the dryer, removed the lint trap, cleaned it out, replaced the seals, and put it all back together. I had to wait a couple of days for the parts because there are no parts stores in my area but they arrived ASAP. Also unless you are a pro I recommend watching the video. It was very helpful for a me, a first time repair person. BTW, I am a 72 yr old woman with no prior experience in repairing dryers and if I can do it anyone can.
