Kenmore side by side refrig has tube with brown water backed up in it. What is the tube for and why is this liquid sitting in it?

There should be an access panel on the back side of the refrig. Remove that you you should see a tube running down into the drain pan. Often that tube gets plugged and needs to be removed and cleaned. If it is a rubber tube, consider replacing it as the rubber gets old and sticky with age and that stickyness causes the plugging.

Thank you for your post, friend!

I understand that you are seeing a brown liquid come from under your dispenser area. I would recommend you having a professional come out to your appliance to check and assure the water lines are connected properly and not developing any moisture problems to form from under your dispenser. I hope this is helpful. -Matt

The water is from the melted frost of the defrost cycle. The drain at the bottom of the back wall of the freezer is blocked so instead of the water draining into the pan where it will evaperate,it's pooling on the freezer floor and freezing, in many case when the floor indent is full the water will leak onto the floor.By pulling the refrigerator out from the wall,there will be a tube behind the service panel on the right side when looking at it from the rear,that tube can be removed and cleared,then clear the nozzle it connects to inside the freezer.

I hope this helps you to stop the leak,

The water tube to the icemaker inside the refrig maybe frozen up. Thaw out with your hair dryer. To make sure the tube is clear. Shut of the water to the refrig, disconnect the inlet water line to the icemaker. Insert a flexable through the connector fitting, I used a zip tie. The flexable item should go all the way to the icemaker

Solution #2 Replace the "water inlet valve" at bottom back right of refrig. Easy To Do.

Solution for laywoman, running off from normal is not a good description. Say is is not cold enough for your use, the normal range is 0 def for freezer and 44 for refrig.
If is is bit warm, say 50 deg refrig, 10 deg freeer. then check it the evaporator coils a frosting up. Check by pressing against the back suface and listen for ice build up back there. Do you remember the refrigerator defrosting ?, and listening for the condensate to drip into the pan on a daily basis, say about 6 hours. and next check your condenser under the refrig. vacuum and brush clean the asselmbly. of condenser radiator coils. Was there water liquid. water , a bit, in the water pan. How is refrig operating now?
Not good enough, then pull the or say unscrew the screws holding the back panel. See the black can compressor, with pipe tubes sticking out. While running. it may be that the tube on the left is cooler than the one on thel right. Is the warmer tube very hot to the touch.
If the tube temperatures are not too different to the hand touch feeling, OR if the back freezer surfaces are frosting it is time to call for a tradesman. Good Luck..

Good day,
Cause is the water valve on the back of the machine. Common problem. Leaks on the off cycle causing your problem. Replace the valve.

This problem is the dual water control valve coil for that side. If you fill the ice maker with tap water and it cycles then the problem is most likely the dual water control valve on the rear and near the floor. Also make sure that the fill tube inside back of ice maker is not frozen over. Let me know the model number and I can tell you the part number for the replacement, Kenmore model numbers look like this for example 213.256489 Thanks, Sea Breeze

it could be either gas problem or may be compressor is not working

iced up drain , clean and defrost drain

I've got a possibilty for you. moisture will build up in the cabinet of refrigs and then cause a little bit of rusty water that will leak out onto the floor. you could also have a plugged drain essentially causing the same thing to happen. look under you veggie bins for water build up. hope that helps. peyton
