Examine the rear of the fridge, found drip pan was cracked. Looked like a hard time getting the old one out. Used gorilla glue to fix the rear and left front cracks. Next time it defrosted, had a leak in the right front corner. Ordered new drip pan, looked how it was installed on your video. Had a tough time removing the fan assembly, but got it done. Its no wonder how or why it cracked, its too tight to get the fan assembly in there without forcibly getting it in there.
