Oven iigniter burnt out

My neighbor, a retired electrican, came over and almost had to take apart the total oven to get at the igniter. It was very difficlt to get at and take off. I don't know who disigned this, but it sure was not designed to fix easily. Products are not designed to be fixed. The companys want us to buy new products. America is a throw away society. Anyone trying to fix this part on their own: Good Luck!
