Today my refrigerator started leaking from under the unit; We pulled out the frig and the water line was dry, but a substantial amount of water keeps pooling from underneath, on both sides (frig and freezer). Everything else works just fine...the only way we have been able to stop the leaking is to turn off the water supply, which also stops the ice maker (I assume), and also turns off our water in the kitchen...can anyone help me?

Re: Water leaking from bottom of unit
For original poster: Check all milky white colored (polyethelne) plastic water lines. These lines tend to get brittle and can crack over a period of time. They extend from the water valve to the ice maker, and from the water valve to the inside of the refrig to a "radiator" so the water can chill, before it runs back out the refrig, past the left side of the refrig behind the bottom grill, through a coupler, and up through the bottom hinge of the freezer door. I'd also advise putting in a separate shut off for the water supply to the refrig so you can have water to the rest of your house when you have a problem with the refrig.
For next user with similar problem: you can check the above, but it may be that the defrost drain is plugged. (on a S x S unit, it is located at the bottom of the freezer compartment, behind the back wall.) If you have a layer of ice on the floor of the freezer, that's a dead give away of a blocked defrost drain tube, Use a turkey baster with hot (not boiling) water to flush it out.

My name is Peter. I am a retired field service refrigeration technician.
I am sorry to say you have a serious problem.
The water supply line to your ice maker runs up the back of your refrigerator from the ice maker solenoid. It is a separate water supply line.
Your water dispenser water line runs from the water dispenser solenoid under your unit and up from the bottom of you freeze door.
You have a plastic tubing leak within your freezer door. Calling a service company to replace the freezer door tubing - a good service technician would not replace the tubing - the damage has already been done.
The insulating material in your freezer door is soaked. The water in the door will cause the door liner to expand and crack. There is no way to completely dry out the insulating material.
The only fix is to replace the freezer door. So, $300.00+ for the door and $150.00+ for the service tech. No, a hair dryer will not do it.
May I suggest:
1.) Remove the bottom toe plate (Kicker plate) in the front of your refrigerator.
2.) Turn the leveling screws counter clockwise so you can pull the refrigerator out to get behind it.
3.) Unplug the unit.
4.) Remove the screws from the bottom cover.
5.) There are two connectors to the solenoid valve to the water dispenser. It is the larger diameter tubing running under your refrigerator.
This will disable your water dispenser. If you see cracks on the inside of your freezer door, seal them with a high temperature silicone adhesive.
If you elect to purchase a new unit, check out Sears Outlet (Scratch & Dent) Stores.
you may have a pin hole in your water line to your dispenser or you could be leaking at the water valve itself on the water dispenser side. you'll have to pull the refrigerator out from the wall and look where the main water line goes into the back of the refrigerator. you will probably have to take the back off to see. be sure you put the back of the refrigerator back when you are through.
If its leaking all the time you could have a problem with the water supply line (if it has an icemaker)Or the solenoid valve (water valve) that opens to refill the icemaker after it drops (harvests) the ice.Or the plastic water lines that run from the valve up to the icemaker.You should pull the frig out from the wall and check the back for leaks.You could also Just shut off the water supply to the unit and see if it stops.These leeks cause a lot of damage when they go unnoticed for a long time.I would check it out asap.
The drain hole at the back certer of the fridge is blocked up,Stick a straw down to unblock,then pour a smal amount of hot water down to make shure it goes,check monthly,the water goes ontop of the commpressor then evaparates
test: first, turn off water supply to frig. then dry up all water. then ensure frig is running at right temperature. now gradually turn on water and observe where leak is. My guess is it is overflowing the ice-maker. there is an adjustment for this. pop off the cover over the end of the ice-maker. look for a screw adjustment. turn it counterclockwise.
