I was at my grandmother's apartment last night. She has a new fridge and when I opened the door to look, can hardly even see anything! Don't know how to remove the light cover on the top underside of fridge. This is a new fridge and there is so little light - thought perhaps of just taking off cover so she can see in the fridge. Or - trying a higher watt bulb. I don't even know how to get the cover off.
