No, but correctly diagnosing it would.
You wanna change parts, I'm sure you can do it very well.
After all, you're college-trained.
Luckily for the owner, there are a limited # of parts in
there. Unluckily for her, they are expensive. And merely putting

they must have taught THAT one in the credit hours you missed out on.

Or, I may call you a pissy little bitch who doesn't know how
to fix an ice machine, nor how to take good serious advice , given
civilly, in a civil manner.
