I have an LG electric double oven that has self clean and easy clean modes. When I set it to self clean or easy clean it says door open on the display and the locks aren't engaged. Now here's the kicker, I can lock the oven doors when they aren't in self clean mode (i guess it's a safety feature for small children). they just won't lock in self clean or easy clean mode so I know the actual lock is working. Any ideas?
