The drain line is plugged allowing water into the inside of the fridge. How do I unplug the line?

water may not be leaking inside? What u may have is water condensation? this happens when u have a clogged or plugged evaporator drain plug line or bad seals on the door which allow air and moister to come in and CONDENSATE, THEREFORE WATER IN THE FRIDGE. U NEED TO CLEAN THE DRAIN LINE USE HOT WATER, AND A SOFT FLEX TUBING OF SOME TYPE

• If your refrigerator leaks water, you have a problem with either a water line or a drain line. If your refrigerator has an automatic icemaker or a water dispenser, the water supply line could be broken. Automatic icemakers have a drain line that runs down to the drain pan beneath the fridge. Mold build-up inside the drain line can lead to a rupture that allows water to escape .A broken drain line can also lead to water leaking from your refrigerator.
  

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

There is a drain that carries water from the freezer to a drain pan in the base of the fridge. It has plugged preventing water from draining and in turn the water has froze blocking the flow of air to the fridge. First you must find the drain line in the rear of the fridge and unplug it as well as thaw the fridge out overnight to allow the water to drain... be patient as there will be a lot of ice to be thawed out, let me know if it works! good luck!

Your problem more than likely is a plugged defrost line in the freezer...The freezer goes through periodic defrost cyles to keep the coils from freezing up. The water catches in a trough pan in the freezer and flows through a drain hole to the bottom of the fridge where it evaporates. This drain hole perodically freezes up and the water accomulates under the freezer bottom until the water level reaches your vent ports to the fridge section. Open your freezer and on the bottom floor of your freezer you should see two screws near the front on either side. Remove them and then take out the bottom tray....this will expose the drain hole near the rear of the freezer compartment. You will more than likely have to remove ice under the tray in order to see the drain hole. Remove the lower back panel on the back of the refrigerator and you should be able to see the drain line coming from the freezer. Unplug the refrigerator before you begin work. It will take a little while for the drain line to thaw to allow liquid to flow to the bottom. I find a hair dryer pretty handy in speeding up the process. To verify you have unplugged the drain line you should be able to pour hot water in the drain hole in the freezer and see it come out at the rear of the fridge in tube line just above a little catch pan

you have to take the center bar down inside the fridge. It is the bar on top of the fridge compartment that houses the lightbulb. Unplug the fridge and unscrew the bar. There is one plug that must be unplugged, then you can pull it down. In the back is a small reservoir for water melting down from the freezer defrost, and a small tube stuck into a hole in the backof the fridge wall. pull the tube out, then flush hot hot water mixed with bleach into that hole. It will flush out anything stuck in the drain tube. If this doesnt work, you will need an external drain kit.

condensation- bad door seals. replace seals.

in fridge- condensate drain plugged. unplug drain under coils.

under fridge- condensate pan full. empty pan.

If the unit has an ice maker or water dispensor, etc. there's always a chance a connection is loose or a valve is leaking by. If no other water is hooked up to the refer, then the defrost cycle water that should drain down to the bottom underneath pan is what is likely. You may have to take the inside rear panels off to see if the drain line is plugged up, that would allow water from the defrosting of the coils to drip inside the fridge vice outside like it should.
