David D Summerville , SC October 31, 2022 Error code f97 Replaced the lower oven fan and board attached to it. I built a platform and after removing both doors and the 4 screws I slid it out on the platform. Removed a lot of screws (3 panels) swapped fan and board on the bracket and put it back together. About 45 minutes. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
