Is your problem fixed yet?

the drain tube is most likely clogged. if the lower vent is freezing up there is no way to confirm because it is covered with ice. the reason water leaks onto the floor is, the refrigerator goes into defrost, frost melts and runs down the ice to the door. use a hair dryer to remove all ice, then use hot water to check drain. drain tube may be up to a foot long and may have a trap. you may have to go in through the back to gain access to the drain

Hello,

You have a clogged defrost drain line. Remove the back panel and chip the ice away pour hot water to clear the defrost drain. Let me know,

check the defrosting timer or adjust it or replace if deffective.

The defrost drain is plugged up. it is at the bottom rear of the freezer section. you may have to remove the back cover to access it.

use hot water and turkey baster . force the water down the drain till it clear's to prevent it from freezing again install drain heater . some model's need them.

I have an LG armoire style fridge/freezer and it had lots ice in the bottom and would eventually drip onto the floor. The problem was with the defrost controller. The moisture that enters the freezer when it is opened condenses and freezes on the freezer coil/fins. There is a heating element that sits under this coil which gets turned on by the defrost controller to melt the frost/ice. As the frost/ice melts it drips into a metal tray which channels the water to a drain hole to have it drop into the drip tray underneath the unit for it to evaporate. The problem is that the before the water has time to leave the freezer, it freezes thereby plugging up the drain hole and thus causing subsequent defrost cycles to have the water flow into the bottom of the freezer where it freezes. Eventually the bottom of the freezer fills up with enough ice for the melted water to flow onto the floor. I had my defrost controller replaced (just outside the warranty period!) and it worked for about 1-month and then same thing happened again. Instead of paying for another defrost controller that would probably not work 100% my serviceman used the old paper-clip trick. He took a paper clip, stretched it out and then wrapped one end around the heating element and placed the other end into the drain hole. Thus when the heating element comes on the paper clip keeps the drain hole warm/hot and prevents the water from freezing. It has been 9 months since this fix and I haven't had any ice pooling in bottom of the freezer.

When I had the problem and started diagnosing it I opened up the freezer, pulled out the racks, draws, and eventually the door. Then I removed the ice maker and then a few screws and carefully removed the back white wall panel disconnecting the fan and any other electrical connections. Behind the panel you will see the cooling coil/fins, the heating element, the drip pan, and drain hole. Most likely you will see a sheet of ice everywhere. The best way to remove the ice is to boil a bunch of water in a tea kettle and slowly pour it on the ice to get it to melt so that you can start breaking out the pieces. Have a sponge and bucket ready to remove the water as the ice starts to melt. Eventually you should get all of the ice removed and get the drain hole unplugged. After all the ice is removed, you still need to fix the real problem by replacing the defrost controller, using the paper clip trick, or both.

To poshodian: There are a few more posts about this problem. Of course, in order to fix it, you have to remove the panel hiding the condenser coils behind the grill and showing the drain hole.

This is what I just posted on one of them:

I’ve had my Maytag 2454 fridge for 8 years. But only this week did the same problem show up as cathy824 and lew223. When I poked a drink stirrer into the top of the drain hole, it was hard as a rock. Not knowing why condensate from the coils was not draining into the hole and tubing that would empty the water into the pan evaporator on the bottom of the fridge, I took everything apart in the back and messed around with the black rubber elbow at the other end of the drain plug. I shouldn’t have bothered, because what I finally did was to pour boiling, boiling hot water over the drain hole to melt the ice and gunk that was frozen solid in the drain tubing. While I was doing that, I poked the stirrer into the hole, washing the gunk down the drain and into the very dry evaporator pan. Keep pouring hot water into the drain hole until you’re satisfied that water can flow freely into the pan.

That solved the problem of condensate water freezing on the bottom of the freezer and running onto the kitchen floor. Thanks to lew223 for the fix! The fridge should be good for another 8 years now.

Sounds like you have a side-by-side...

The defrost drain is probably clogged or frozen. When the fridge runs a defrost cycle the melted water cannot reach the evaporator pan underneath the refrigerator. Some water makes its way out onto the floor to wet your socks, and some re-freezes inside the bottom of the freezer compartment creating a layer of ice.

sounds like 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

I had a similar issue that started about a year ago with my Sub-Zero 550. My freezer gasket actually tore after several times of freezing closed. I thought that a new gasket would solve it, but a second but related problem developed where I was getting alot of condensation under the left side of the unit, with the water dripping onto the floor...eventually staining the hardwood floor in front of the unit.

I traced the problem to a clogged condensation drain pipe in the refrigerator. It is a corrugated pipe that drains a trough behind the crisper drawers. My pipe was clogged with black sludge and frozen down below. The condensation in the fridge would overflow out of the trough and leak below the crisper drawers, down out through the gasket.

To resolve, I used a piece of solid thin wire folded in half and twisted with a small loop at the end to fish out as much sludge as I could. Then squirted hot water into the pipe until it totally unclogged. I believe this will solve the problem without any need for a heater underneath the unit. The 550 worked fine for 4-5 years before this happened.
