what are some good first steps to get into working on more machines (more info in comments)?

basically my dryer broke and I couldn’t afford to have someone look at it, so I researched all the possible issues and was able to fix it myself. I know it’s not overly complicated to fix a machine like that, but I can’t explain how good it felt to work on it and solve the issue. I realized I really would like to work on stuff like that (doesn’t have to be dryers, just any type of machinery).

I was wondering what’s a good step for me to take, to get into working on more stuff like that. do you know of any fun easy projects to do that will help me learn? what classes could I take to start learning more about it? I wanna learn about small motors and electrical parts. I know this is extremely vague but anyone who has a hobby related to it, could you give me some advice? I’d really appreciate it.
