The interior or optional lights stopped working and we can't seem to figure out how to fix them. It seems as though everything works from the upper left hand panel, but it's all Greek. Also, the small individual bulbs have a slight darkened tinge so i am thinking it may be a fuse, but how do I go about changing it? Just to be clear, this is the glass door model and NOT the appliance bulbs, but the accent lights. Thanks!
