My wife went to run the self-clean cycle on our GE wall oven/microwave combination. When she pushed the self-clean cycle button, the "Locked Door" indicator came on and the oven does not work now. I tried to run another self-clean cycle but it didn't work. I pushed (and held) the clear button for 10 seconds and nothing happened. I also set the electric breaker to "off" for five minutes. Nothing...

Does anyone know what steps I can take to reset the oven so that it works, or how to test what part needs replacing or links to a service manual?
