Water freezing on floor of lower draw under ice maker


Freezer /fridge water/ice in fridge and or freezer

Usually due to CONDENSATION due to bad door seals or a plugged evaporator drain line? Can use a soft flexable tubing and very hot water to clean it out. Bad door seals usually need replacement, but u can use a blow dryer and something to pry it closer to the door wall while blowing hot air on to it. To create a seal, to test for bad door seals place a dollar bill in between the door and wall of fridge where it closes. Then slide out the dollar bill with door closed. It should offer some resistance and not be easy to pull out.
Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced. ( usually the line is under the freezer bottom plate covering. Towards the back of the unit) And there is another inside the fridge area also.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.

Subz 550 drain tube keeps freezing up, causing water to spill onto base of fridge and freezing


i know this is late but there's a heater kit made for this 4202160 is part number,you remove the shelves,you can put a mark under the shelf arm on the far outside where the shelves hook on so you can put them back in the same spot,then remove the light cover,the two screws and metal cover and then pull the wall off and set it to the side ,the drain heater kit plugs into the wire harness,the heater will heat up and keep drain from freezing,you can slide the tube off,stick a screw driver in to hold it down to the floor so you don't burn your hand and blow hot air into it with hair dryer to melt out ice,keep heat on for like 20 to 30 seconds then cold air or remove heat you don't want to mess the hose up from overheating wait a bit and hit it again until you melt out the ice,then i use a long plastic wire tie to stick into drain hose to clean it out,some nasty stuff in there,i use a steamer to clean the line out and then i have a piece of 1/4 inch plastic water line to snake into the drain,if this is the first time this has happened you don't need the heater kit,just clean out the tube and metal drain trough,also clean the back of the top crisper drawer shelf,crumbs and stuff can get in between the back wall and the top shelf and then will fall into the drain,if you keep that area clean you won't have to many issues and keep the fridge a little warmer so it doesn't freeze up the water in the drain tube,put the drain tube back onto the trough and pour hot water into it,if it drains down you're done if it's still blocked get a turkey baster and push hot water down into the drain tube to clear it,if it still doesn't clear remove the bottom kick panel,you'll see the drain pan and look at it because you have to get it back the same way in the clips then you can see the drain tube,stick a plastic tie up in there to clean it,sometimes there could be dust or something in the drain pan,when the water hits it it can get into the bottom of tube and block it but i've only had to do that once,hope this helps you out.

My bottom freezing compartment some how gets water in it and then it freezes what could be the problem?


Hello
The water comes from the self defrost cycle.It is supposed to drain out to a collector under fridge.
Sounds like your drain got clogged causing ice block to form.
Turn off fridge and use hairdryer to melt ice block. You should be able to see a drain hole.Continue to melt using Hair dryer and hot water.Once ice is out of drain tube use some flexitube to gently push out any obstruction(usuually a pea or lima bean!)

Good as new.

Any feedback much appreciated

My freezer is freezing food fine but my refrigerator seems to be warm and not cooling like it should. The temp control has been adjusted to a higher setting but does not seem to help.


if your freezer is working your fridge is fine
Your problem probably started a couple weeks ago when the drain that allows defrosted ice (water) to drain into the drain pan at the base of your fridge became plugged for some reason. Then everytime the fridge went on defrost more water melted but did not drain which in turn froze. Now ice has built up and caused the air that flows into the fridge to be blocked, causing a warm fridge.... my advice is to leave fridge unplugged for 48 hrs to thaw it and find the cause of the water not to drain... could be a corn niblet or pea from the freezer... the tube should be visible from the inside or the back

Freezer drain tube clogs causing water to drain


drain tube is clogging with debris or freezing? is there a pan under your fridge with a float valve on it, these pans are usually heated and the water evaporates, except when the factory doesnt hook up the wires, because it wont pass the eer rating, you can hook up after you, the consumer has purchased it , i know it sounds dumb but thats what viking does as well.
check that pan under your fridge and see if there are extra wires that are unplugged , plug them together(2) and good luck.
initially you will have to shut your fridge down for a couple of hours to defrost, but once you restart you should be good,
empty that pan under the fridge for now as well

Same Problem ...Drain Hole Freezing up.


After facing the same issue (defrosting, cleaning the drain, drain gets blocked again...start again: defrost, etc..) I decided to try to give it one last go:
1. Defrost

2. Clean & rinse the drain (ensure is fully clean and I can pass liquid through the drain).

3. Get a ~30 cm pure copper wire
In my case I took a 3amp power cable, and took the copper wire from one of the cables.

4. Wrap one end of the copper wire around the copper coil at the back of the fridge (where the coil is warmest)

5. Insert the other end of the copper wire in the drain (just above the drip tray). I inserted ~15cm of wire into the drain.

The purpose of these last steps was to ensure there was no "freezing" happening on the drain. The copper effectively will keep the temperature inside the drain above freezing.

Not sure how permanent this might be.. so far at least I'm getting more months than with the previous symptoms treatments ;)

Best of luck!

Ice build up condensation will not drain down the tube to the catch pan under the refiridgerator. As much as 3 inches of ice will build up between the veg bins, causing mold builup in fridge, Model 550...


I had the same problem but fixed it recently. The problem originates with the drain trough mounted on the back interior wall of the fridge that slopes down into the middle. The drain tube is attached at this point and runs to the pan under the unit. This drain trough is screwed to the interior and sealed with silicone caulking. Over time the caulking breaks free from the interior wall of the fridge allowing the defrosted water to leak past the trough, collecting in the bottom of the compartment under the veggie drawer. It freezes there building up an ice ***** that eventuallly wraps around the drain tube. Any water that now runs into the tube freezes in place over time forming an ice plug preventing any drainage at all. Now the defrosted water begins to flood the interior of the fridge eventually leaking out which it did in our situtation.

There are two solutions. One is to take off the drain trough, clean it up and the interior wall of the fridge. Also thaw out the ice plug in the drain tube and make sure it is clean and drains freely. I used hot water and a syringe to inject it into the tube until the ice melted. Dry everything off. Reattach the drain trough using silicone caulking approved for kitchen/bath use. You may have to shut down the fridge and warm it up to meet the application temperature limit of the silicpne. The other solution is simpler. After cleaning and drying the drain trough, I applied an adhesive backed closed cell foam rubber gasket (3/16" thick automotive) to the back surface of the trough that sits against the interior wall of the fridge when in place. When screwed back in place, the gasket is compressed preventing water from leaking past. The fridge does not have to be warmed up for this fix. It has been in place for a few months now with now problems.

Sub-Zero 550 water dripping on right side of freezer forming ice on draw


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.
