micro wave runs when bottom of door is touched .
Our lg 2.0 cubic microwave was delivered by UPS yesterday. When any light upward pressure is put on the bottom of the door, the microwave starts operating. One time today, it started running when I just closed the door. Is there something we can do to fix this or do we just need to exchange the oven? It heats the food really well but the fact that it starts on its own is unsettling.
