Usually in a 220v wiring circuit, the black is hot, the white is hot, and the ground is copper. In your situation, maybe the red and green are grounds. Easiest way, is pop off the front cover of the circuit panel. Be careful, and don;t touch anything live!

WOW! the white wire is not the ground only the green wire is . The White is the neutral wire that carries current for the 120v parts of your oven. These do not get connected together. The Red and Black are the two 120v hot wires that make it 220v for the oven. If you don't want to use the light bulb or any other 120v parts of the oven then connect the Red and Black to the the hots and the green to the ground. Make sure you disconnect any of the 120v parts of the oven so you don't get shocked!!!
