Oven clock/controls not lit unless the oven light is on, either by switch or by opening the door. Not even the lights that show the top burners are on will work unless the oven light is on. The oven light flickers. At one time there was an error code PO EO. We ordered a new clock/control part and replaced it. Still having the same issues, but the only code says Good. I have since realized that the oven, timer, burner and hot lights will work if the oven light is on.
