Nice. I just fixed my Samsung dryer. The drum was binding or something, about 50% of the time it would make a buzzing noise when started and it wouldn’t spin. One of the wheels inside was hard to turn when I took it apart. Replaced 2 wheels, belt, tension arm thing, and motor. Was like $80 in total. I did that yesterday and so far so good. I’ve had the set for about 10 years too so I’ll remember this if the washer stops working.
If you are renting and have no practical skills to actually fix this, just leave it alone. You are likely to fuck up the floor worse trying to do these home remedies.
