After identfying that the problem was due to a damaged drum support roller, I decided to replace the bad roller instead of replacing the dyer itself.
The first thing was to remove the front cover and the front panels to expose the drum. (Only a few screws hold them in place.) Next, the drum was removed by first releasing the belt from the motor pulley and tensioner, and then pulling the drum straight out.
At this point the two rollers would be exposed. The triangular plastic retaining locks were removed by slightly prying them off. The old rollers were then removed and replaced.
Before putting everything back, this was a good time to vacuum all the accumulated lint inside, especially the lint that had accumulated around the motor assembly and the fire box.
(A pleasant surprise: I found a lot of coins inside the unit, enough to recoup half of what I spent for the new rollers.)
I removed the two screws on the top by the lint catcher. Then, per information from this website, I pried up the top. I reached down into the dryer and removed the two screws on the broken door switch and replaced it with the new part. I am a recently widowed, 55 year old and was thrilled to find good advice, information and instructions on your website!! Simple as could be!
The only thing I had to do was hammer the catch inside the square fitting and presto it was done. It took me less than 3 mins. I thought I might of needed instructions, but it was really simple. Even a guy can do it. (smile)
