All I did was replace the fuse in back of oven. I have an Accutemp oven which was not heavy at all and no problem for one person. It was so easy, just a few screws, it can't believe I might have paid someone to fix it. When I first found my oven not working I thought I was going to have to get a new oven, but instead, $35 and ten minutes of work, my oven is back in perfect health.
