The oven (model ykers507ew1) was showing the meat probe light and the oven would not come on. I tried unplugging and replugging, the meat probe light no longer showing, but oven seems to start OK for about 10 seconds then quits, F-4 code right back. I gambled on a new temp sensor and it still does not work. Also notice a couple of big clicks when plugged back in, maybe the self-clean lock, probably normal? Any ideas? Thanks, Mark
