PSA: Check your oven racks before you preheat
So I got a new to me oven last week, a used GE from a guy on Craigslist. Fired it up to bake a batch of sourdough boules, set it to 475 degrees. Threw my Dutch oven in there to preheat like always. About 20 minutes later I smell smoke, open the door, and the top rack had slid down and was sitting right on top of the element. Melted a plastic handle off one of my pans and filled the whole kitchen with nasty burnt plastic smell. Had to take everything apart and scrub for an hour. Turns out the little plastic stops on the rack slides were worn down. Popped them out and replaced with some metal clips from the hardware store for like 3 bucks. Has anyone else had racks slip mid bake? How do you keep them from moving around?
