Natalie B Metropolis , IL October 04, 2018 Needed replacement insulation, mice issue Took the sides off oven, removed old insulation, placed new insulation in it's place. I later had to order a piece for the insulation in the back which was more tricky, but with time and a little finessing, it was fixed and ready to bake a pie! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
