Hello Jim. The control panel W10306627 could have a stuck button. Here is a test we can perform to determine this. Hope this helps. Touch Panel and Electronic Control Test The microwave hood combination is provided with a self-diagnostic routine that can be accessed through the touch keypad. To initiate this routine: 1. Press and hold CANCEL/OFF while opening the door. While still holding the CANCEL/OFF button, unplug the microwave oven for 2 seconds, then plug it back in. 2. Release the CANCEL/OFF button and close the door. 3. After pressing each button on the control panel, “8” will appear in the display to indicate that the circuits are complete and all relays are working. NOTE: If the CANCEL/OFF button is pressed during this diagnostic routine, you will exit the test mode.
