We followed the video online.
It took a bit longer than we thought that it would for 3 reasons:
1) our laundry room is a tight space and the dryer is mounted on top of the washer.
2) we needed to clean the interior because we had, at some point, dried a feather pillow which opened spewing thousands of feathers.
3) the thermal fuse, the old one needed to be removed from a mounting which had the tiniest unusual screw. We could not get it off and prayed that the old one worked. Thankfully it did! I would recommend that the fuse come mounted like the heating element does.
