glass in our oven door seems a bit loose, not the inside glass but the outer piece..

Vicki, you could definitely tackle this repair yourself. It may just need re-positioned. If you end up needing a new piece of glass, the part number is W10535776. But for now, I’ll add a video below showing how to get inside the door. Also, I noticed this model was manufactured in 2013-2014. Is it under a year since you purchased it? If so, it’d fall under the manufacturer’s warranty and you can call Whirlpool directly to handle it. 1-800-253-1301. Good luck!
