The upper (main) oven is not lighting, yet the stove burners and lower drawer oven work normally. I replaced the upper igniter, control panel, and temp sensor, with no change. The upper oven has six settings (Bake, Broil, Clean, Convection Bake, Convection Broil, and Probe). The only function that gets the upper igniter to glow is the Broil button, but it never ignites the flame. When I try the other functions, the temp indicator goes to 100 degrees, and never fails to light. Anu suggestions would be greatly appreciated. Rick Newbury Park, California.
