Maytag Gemini ovens won't light

Oven Repair (including Ranges and Cooktops)

Hi - Both top and bottom ovens of my Maytag Gemini gas range won’t light. Broiler will ignite just fine. Bottom oven ignitor is not glowing. Bottom oven worked fine 24 hours ago. Since both ovens won’t light, sounds like a "common" problem to both. I suspect control unit, but not sure. Don’t know where top oven ignitor is located. ANy help would be appreciated. Thanks
