With microwave door closed the upper heating element in microwave turn on by itself. We have never used the convection part of the microwave. It is very scary microwave heats up with us even using it.
Based on the description of the problem it looks as though the issue will be caused by a bad relay on the control board of your walloven. Part number for the control board is 8302985.
