I removed the covers and heat dispersers (shields)and the burner. I tested the ignitor for continuity there was none. No current through the ignitor. Order from APP.com got the part within a few working days actually on Tuesday. My unit failed on Friday Bummer, I was about to bake bread and did some in the toaster oven and refrigerated the other for 5 days. Baked the last loaf and came out great. This is a great outfit and the self-help videos are a great help. Thank you APP.com.
