Where is the defrost drain tube located? I believe mine is blocked
All documentation I have from sears does not show this tube or its location The automatic defrost cycle works on my fridge with a bottom freezer, but lots of ice builds up on freezer floor and water pools on floor under both bottom corners of freezer door. I have manually defrosted twice by turning unit off and melting the ice to remove all. As soon as fridge is switched on and freezer gets cold, the problem repeats. My unit is nine years old and this started six months ago. Also, where is the drain tube so I can check if that is clogged and causing the problem?

    Thank you, I will carefully try to remove the back cover, after defrosting again as it is covered with ice, and look for the tube. If not successful I may need your help.

    I am also going thru the same thing. We have a top freezer model, # 106.71182101.

    We have (we thought) thawed it out, but apparently not down to the bottom of the tube.

    So, my question is: where is the tube? Do we have to take the back of the fridge off to find it? the back of the freezer is one wall connected to the fridge, so we can't do that...

You have to take everything out of the freezer, removing the bottom tray and back wall panel, the light, and the ice maker. It sounds like a job but is actually quite simple. Break up all the ice on the floor of the freezer and remove it, being careful not to damage any parts at the back. You'll see a hole in the center of the back area that drains the freezer floor into the tube which leads down to the tray at the bottom of the refridge. The hole and tube become clogged with ice, hence no drainage of water. Pour HOT water back there from a teapot or other container, especially where the hole is, until the tube drains freely. Thoroughly clean all parts and reinstall. Everything should work fine until the next time this unit needs such servicing. To prevent it happening again, don't overload the freezer and especially don't push frozen food all the way to the back of the freezer. Leave a space back there. Kenmore reps will tell you that the more food you stuff in the freezer, the better it will work. Don't listen to this advice. Obviously, a small freezer is intended to freeze a fairly small amount of food. Cramming it full of frozen food will cause problems like this.

Need a diagram of Amana top freezer refrigerator model #ATB2132ARW My fridge has a clogged drain tube, but I can't locate the drain.

I can't find a diagram but have a different model Amana. The drain tube on mine was located just above the drip pan under the refrigerator. It was a soft plastic/rubber and had become clogged due to something sticky that stuck it together. Caused the freezer water to back up and after cleaning the tube, I had to defrost the refrigerator completely to melt the ice blocking the tube at th top (in the freezer). Sorry I can't help with more info.

Water is leaking inside of the refrigerator on the (if you are looking into the fridge) the left side. I cannot tell where it is coming from - i see no dripping from anywhere but it sits in puddles on the...

I have a Whirlpool Top-mount refrigerator. Whirlpool also manufactures many of the Kenmore refrigerators.

A few weeks ago I noticed a puddle of water on the top right shelf in the refrigerator section. I figured out that it must be the water that forms during the defrost cycle and normally drains down through a tube in the back into an evaporator tray beneath the refrigerator. Something was preventing the water from draining away and instead it was dripping through the overflow holes from the freezer into the refrigerator section.

I emptied the freezer and took off the back panel. It actually wouldn't come off at first because all the water beneath the defrost heater which should have been draining out the drain hole was frozen into one solid block of ice. I used a hair dryer to melt the ice (took a while - be patient) and then took off the panel.

To melt all the rest of the ice in the drain tube I used the hair dryer. To clear out the ice in the drain tube, I used a turkey baster and kept putting down hot water until I heard water making it down to the evaporator tray beneath the refrigerator.

The following mod is "try at your own risk" (I wouldn't do this if you still have warranty coverage - call a tech instead):
I made this modification to prevent the problem from recurring (at least that's the hope): Wrapped a piece of wire (unbent a large paper clip) around the defrost cycle heater and stuck it into the drain hole. The theory is that the wire will heat up every time the defrost cycle runs and will keep the drain hole from freezing shut.

One thing I noticed during this repair concerns the drip pan beneath the defrost heater in the freezer (this is the pan that collects the water that is melted off the coils during defrosting). The drip pan does not seem to be angled properly so that the water will drain normally towards the drain hole. I guess water could remain behind then freeze later. I reported this to Whirlpool.

Water leak from freezer into frig mod.70162990 how to fix


To correct the problem, you must locate the drain and inspect it for blockage. Often, you'll find it frozen, but it's usually always solid debris blocking the flow of the water that's CAUSING it to freeze: and that must be removed from the drain or it WILL happen again.
Where is the Drain?
After unplugging the fridge from the AC power, go ahead and pull the unit out where you can access the back. This is also a GREAT opportunity to clean dust off of the condenser coils and compressor, which will GREATLY lower your energy costs! (Use a Vacuum with brush attachment)
Depending on the model of refrigerator in question, the drain port can be located in several places. The most likely location is just under the freezer, which is actually the top of the fresh food compartment: The tube usually comes out there, and down the outside of the refrigerator; (On Back) However, it can also be under the coils behind the false back and/or side walls. At any rate, when looking for it, keep in mind that its' sole function is to drain water away from the evaporator coils when the unit is defrosting itself; Therefore, it's almost ALWAYS just under the freezer at the end of a "channel" that directs all of the water into it.
Cleaning the Drain... Depends on what's causing the clog.
If it's iced up, the quickest way to thaw it is with a hairdryer. It takes just a minute with the hairdryer set on max.

Before you get happy and close everything up though, ALWAYS check the tube for debris.
About 95% of the time, I've found something in a frozen drain line. Remember: It wouldn't have been frozen in the first place if the water had been able to drain off!
After checking the pan under the freezer for debris in the pan and exit hole, you'll need to check the tube itself. The best test is just to blow through it like you would a straw. If it's clogged, you'll feel some resistance.
To clear a clogged pipe: There are numerous ways, but the most efficient is to use a can of electronics duster. (ONLY the kind that comes with a nozzle extension tube) WITH A PAIR OF CLOTH OR LEATHER WORK GLOVES ON BOTH HANDS!: Stick the nozzle extension down into the drain tube. Wrap one hand around the top of the tube and the nozzle to form as tight a seal as you can, and press the trigger. The clog should be blown right out: if not repeat as necessary. Reconnect it all, then pour a little water through it and check for leaks.

Hope this helps!

Good luck.

Water inside refrigerator

Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.

Your drain tube may be stopped up with ice at the upper end because it drains too slow because it's stopped up at the lower end in the evaporator pan under the unit at the floor. It can get dust and mold in it. Once you get the ice out at the top a little pressure with a turkey baster will usually clear it out. Flushing it out with hot water and clorox may help.
Make sure it drains quick enough to prevent refreezing. . The drain should be located below the evaporator coils on the lower back of the freezer.

Mine collects water under the crispers also.

Self-defrosting refrigerators dispose of the water generated during the defrost cycle, usually via a tube or channel that directs the water to a pan at the bottom of the refrigerator. From the pan, the water normally evaporates.

If the tube or channel is clogged or obstructed, the water backs up and leaks into the inside of the refrigerator compartment. Then the water builds up at the bottom, inside of the refrigerator. When the water has built up for a time it may spill out of the front of the door opening. To fix this problem, clear the drain tube or channel and allow the defrost water to flow down to the drain pan.
