Turns on with door open

Question

Hello, we own a panasonic Invertor serial# 6A23280963 model# NN-S933BFOur microwave is turning on with the door open. It runs fine other than that. Presently we are having to unplug it to place our stuff in the oven. Then we plug it back in so we can run it.We just need to know how to reset the computer inside it so it will not run when we open the microwave oven door.Thank you for your assistance.
