I have an LG LFC25770TT French door refrigerator with bottom freezer that has been periodically building up ice at the bottom of the freezer and then leaking out the bottom of the freezer door. It looks like the water is coming from a panel on the left side (looking at the freezer). It's difficult to see in the photo, but you can see a line of ice on the left side. I'm guessing this is a clogged defrost drain line, but I don't know where to access the drain line to clean it, defrost it, etc. If someone has a service manual or can provide instructions for this model, it would be greatly appreciated.

Yes, you have a clogged defrost drain. To access the drain, you'll have to remove the freezer drawer and back panel from the freezer. Though the back panel fits tight, it can be pulled out. To unclog defrost drain have some towels at the ready and pour boiling water onto the ice at the bottom of the evaporator (cooling tubes). Don't chip the ice because you risk damaging the cooling tubes and they're really thin. If you pierce the aluminum, you'll have to buy a new refrigerator. Once you get the ice melted, the drain will be obvious ~ it's big enough to put your pinky finger into. Water should flow freely down the drain. Be persistent. You can also remove the back panel of the refrigerator to access the drain tube from the bottom. Often times, there's a gizmo at the end of the tube intended to keep bugs out and cold in that gets clogged up.

Thanks. Is it possible to melt the ice from the drain tube in the back? Is there a diagram or video for how to remove the back panel from inside the freezer?

It is possible to unclog the drain tube from the back it you have a hand held steamer but you won't be able to melt all the ice solely from the back. After removing the freezer baskets and freezer drawer, remove any screws that you see in the freezer back panel ~ there will only be a few ~ and then grab the bottom of the panel and pull it out. Don't yank it out completely because there will likely be a fan or fans attached so you'll have to pull it partially out then reach behind and unplug the various wire connector plugs.
