We tried to perform self clean. The oven never completed the cycle so we cycled the power. The oven had an E15 code when restarted and the oven door was locked. The manual indicated to check the wire harness and replace the oven relay board and controller. I replaced the boards and checked the harness (which was fine). The error went away, but the oven door is still locked and the oven display/touch controls do not work. There is no clock display either. Stove top now works fine and there are no errors. Does anyone know what to check next?

Thanks!
