The interior lights wont turn off. they melted the old light bracket so i replaced it and the lights still wont go out

It sounds like you have a switch that isn't closing when the door shuts. I'm not overly familiar with the LG's, but looking at the Sears Parts Direct site, it looks like the door switches are in the hinge covers on top of the unit. There should be two of them, one for each door. But, only one has to not be working to keep the light on. The first thing I would check is to make sure the hinge cover isn't loose or out of position. The switch should close when the door closes. If the hinge cover moves, then the switch won't close. If everything is tight and aligned, then one of the switches is bad. That can be checked with a volt meter that does continuity checks. Unplug the unit before checking because those wires should be hot at all times. If you don't have a meter and want to do trial and error, just buy one switch since they both are the same. Here is the parts diagram showing the switch locations and part numbers:

The switch is 402A on the diagram, located on top of the box. If you click on the parts diagram, you can enlarge it to get a closer look.
The switch part number is 6600JB3007E
Hope this helps
