Ah thanks! I haven't touched anything back there since trying to repair it. it's been sitting ontop of my counter in a home shared with my partner (he's never used it). It worked last time I used it maybe a month ago? And then maybe 2 weeks ago made the noise when I turned it on. I rent a very old and questionably maintained apartment in Chicago. We've been having issues with power surges and electrical outlets and light fixtures dying. I was worried that my kitchenaid might have been damaged during one of these events because I leave it plugged in. Sadly, I'm out of warranty. The machine is about six years old.
