Good old RU-vid U. That's how I learned electronics repair, and I've had a ball. My partner and I had a similar thing happen to our dryer a few months ago, where it made a loud noise when it was on. He's in industrial electronics, so he dove in head first while I was looking up videos. Between the two of us (mostly him), we found that the drum had moved out of position. Just needed to be reseated. Saved us a lot of money to go in ourselves.
Been watching the channel since around 2018 or 2019 when I followed your RGH 1.2 tutorial to RGH my first xbox 360, it was my first real soldering project outside of some soldering that I did in a high school class back at that time. If I ever want to look into modding a console I always come to your channel since your guides are very very good (best on RU-vid imo)! I've never stopped by to check out a Mario's Minute and it seems like I need to start listening to them. I noticed on one of your episodes you had Octal on so I'll definitely have to check that one out. You should try and see if you can get Spawn Wave on sometime, or perhaps maybe sometime you could go on his podcast. That would be interesting to listen to!
