Joel P Livingston , TX January 03, 2016 Appliance: KitchenAid 30" Kitchenaid Free Standing Range Dual Fuel KDRP407HSS13 Kitchenaid Range Kdrp407hss13: Both light bulbs burned out in my dual fuel kitchenaid oven. How to replace Light Bulb. Replaced both bulbs, Not easy, but much better than paying a repair man. Your diagram of the oven made it very easy to find the correct parts, works fine now.
