The door lock motor is not detected by the relay control board. Wait 30 seconds and get the power back on. Start a clean cycle if you want to try and lock the oven door again. Check the wire harness connections between the door lock assembly and the relay control board if the door lock motor doesn't run. If the wire harness is damaged, replace it. The door lock assembly should be replaced if the wiring is okay. The relay control board needs to be replaced if the problem continues.
