Have an LG LRTN18310WW top freezer model (no ice/water features). It leaks water from the freezer into the back of the fridge below at the back.

If you have water build-up on the floor of the food compartment, or ice buildup on the floor of the freezer compartment, you are probably suffering from either a frost problem or from a clogged defrost drain.

Remove everything from your freezer, including all food and any shelves. Do not remove the icemaker (if installed.)
Look at and feel the panel covering the bottom or back of the freezer compartment. Is it thick with frost?
On top freezer models, are the holes in the top of the food compartment that lead to the evaporator choked with ice?
Is there ice forming on, or lots of water on the ceiling of the food compartment?
If the answer is yes to any of these questions, there's probably a defrost problem.
If you suspect a defrost problem, first remove any icemaker that may be installed. You will see a removable panel covering the entire back or bottom of your freezer compartment. There may be 6 to 10 or more screws holding it on. In some units there is a light socket attached to the panel; you'll see this arrangement most often in side-by-sides.

If you start to get an unusual buildup of ice in one particular spot in your freezer, especially beneath the icemaker, check for water leaks.
Water leaking onto the kitchen floor not traceable to one of the problems in Chapters 4 or 6 may be from a leak in the icemaker or door dispenser water system. Icemakers have a water solenoid valve mounted on the back of the fridge, usually behind the back bottom panel, and a water tube that leads straight up the back of the fridge to the icemaker. Door dispensers have a similar water solenoid valve with a water tube that leads beneath the fridge and into the door through a hollow hinge. If your fridge has both features, it's usually a dual water solenoid valve. It can be simple or not-so-simple to fix, but basically it's just a plumbing job.

Richard, sounds like the drain plug/ hole is plugged.

How to Unclog Refrigerator Drain Line

lg ice beam refrigerator which has door cooling also is not cooling properly. the freezer is working there was ice accumulated in the rear corner of the freezer i defrosted but still the fridge is not cooling and there is a pool of water at the bottom most of the time. sometimes i see the fan inside the fridge is not working

Hello, this sounds like you have a blockage in the drain tube, remove panel back/bottom of freezer..you may see ice build up...melt ice with hair dryer/heat gun...you will see a pan below evaporator...melt ice in pan...dry water up in pan with paper towel...now you should see a hole in pan that leads to drain tube...pour some hot water in pan..wait a couple minutes..mop up water and repeat this step 2-3 times....once you have done this find some flexible curtain wire or electrical wire..poke down the hole until you see the water drain..now it is clear..put back panel back and you are good to go. The reason you see water in the fridge is because the water has been leaking into the freezer and down the vent into the fridge instead of running into the drain hole...Please feel free to comment again if you have any other question. Mike

ok...1st there is only one connection to the fridge at the valve.2nd check the filter and see if one is present.3rd make shure the child lock out feature on the dispencer is not activated.

Same issue with water leaking. Fan slowed and allowed ice to block drain..., defrost caused ice dam under heat shield. (behind freezer fan shroud at bottom, below condenser) Ice dam lifted heat shield until it dislodged the condenser, which slid down and melted the plastic liner when the defrost came on. QC! Fixable..., but could have been avoided by mounting the condenser so it couldn't shift or drop in transit.
New fan and heat shield needed now..., and more groceries!
Any good leads on reasonable parts in Belleville Ontario area?

its possible that the drain pan behind the back freezer wall is clogged or coverd with ice, sounds like when unit goes into defrost melt water leaks under sides of drain pan and into fridge. unplug and remove back freezer wall if drain is covered with ice defrost the ice, can be prevented by loosely coiling a piece of solid copper wire around element and into drain slightly radiant heat during defrost should keep drain fromicing over. if drain is just clogged wth debris clean drain and you should be good to go, hope this helps you.

sounds like clogged water drain

in a side by side it is located in freezer section at bottom

in top freezer ref it is in freezer too but behind back cover


if either are iced over remove ice and pour sum really hot water down drain until u see it go down

Defrost water from a top freezer models exits the cabinet in the rear. This drain line may be plugged.
