I have an LG fridge (LRFD25850ST) which sometimes has water pool on the floor under the freezer and also ice accumulate on the bottom of the freezer. I have traced the water back to the evercold water box on the door. Any ideas where to go from there? I can't see how to get the evercold water box off to diagnose further. Thanks!

Orange glow is defrost heater and that is normal. Crackling sound is heater heating up area around it, normal. Water and ice build up in the bottom is due to a clogged defrost drain.

Check that the defrost drain of hole is not blocked

Water Running in Refrigerator from Freezer

is there any ice on freezer floor or is the bottom rack iced in?if so you have a blocked drain in the freezer,or if that's ok you could have a crack in one of the plastic water lines,also check the catch pan where the water drains into when the fridge defrosts,you can pour water down the drain in the freezer to check that,roll the fridge forward and take the bottom panel off the back,should be easier to check for leaks and take off the front kick panel,while you're in there vac out all the dust in there,front and back,you should do this every 6 months

is the defrost drain blocked(ice on freezer floor)

If water appears on the floor in front of the refrigerator once or twice a day, it could be due to a clog in the defrost drain tube. The usual evidence of a clogged drain in a side-by-side refrigerator is ice under the bottom basket in the freezer compartment, in addition to a puddle of water on the floor.

The drain is plugged. This fridge will defrost every 8 hrs or so. When it does , it will melt the frost that has built up on the evaporator. This melted frost will run down a drain under the evaporator to a drain in the bottom directly under the evaporator. When the drain gets plugged the water cannot drain out of the freezer compartment. After several defrost cycles the melted frost will overflow onto the freezer floor. When the fridge starts back up it will freez this water is the bottom of the fridge. sometimes this water that is now ice will melt on the next defrost cycle and actually run out into the floor. You will have to unplug the fridge or turn it off, then remove the cover to the evaporator. Get a hair dryer and melt the ice aruond the evaporator and drain. Once the ice is removed, check the drain and try to clear it. Once clear, replace everything but the shelves. Plug the fridge back in or turn it back on. Observe and listen for the evaporator fan. It should be running now. When working on the ice on the evaporator always be carefull. The defrost heater can be damaged if up push or pull on it too much.

I don't have the same refrigerator, but had a similar issue with a GE. Melt the ice at the bottom of the freezer. I think the water comes from the auto defrost feature. There should be a hole at the back bottom of the freezer that water would go into, and run to an evaporator pan under the refrigerator. The tube may be blocked that allows this water to drain, so it is backing up in the bottom of the freezer, and overflowing through the front bottom of the freezer to your floor.

did you try to remove the 2 ***** in freezer floor???. if not remove the floor and check for ice build up underthere, if so:

you have a clogged defrost drain tube. removing back panel of freezer will give you acess to drain trough, melt away the ice with a hair dryer, youll find a drain hole under there somwhere,pouring boiling water down the drain will clear it pretty quickly( i use a steam machine purchased from the infomercials works awesome, after you clear it and all water drain down tube wrap a piece of solid copper wirearound the heater( black calrod heater right above the drain trough) and stick it in the whole maybe an inch or so. now everythime the heater comes on to defrost it will prevent the hole from freezing over
