There is a good possibility the drum got dislodged of the drum support rollers (#44 on the
bulkhead parts break down diagram) or the roller(s) is worn out.
You can find the complete disassembly instructions in the one of my previous posts:
No Dryer Heat
At the same time I would recommend to clean the dryer from the lint built up inside.
- The part number for the drum support rollers is
AP3098345
- Here are the break down diagrams for the Estate dryer
Model TEDS680EQ2
Good luck and Happy New year.
