The original problem was the fan motor had died, and the oven heated very unevenly. When I removed the ignitor and burner to access the fan blades, the ignitor disintegrated, which I then needed to replace. I found the repair manual on the LG site for my stove, which provide pictures and step by step directions for replacement of all the parts. But did not warn me about the ignitor being extremely fragile. Once I had all the parts, replacing them too only a short time.
