The water in the water line freezes up and we have to use a hair dryer to thaw it out. The unit is 7 years old and this is a new continuos problem. Have turned up the temperature as well as adjusting items in freezer. Seems strange to have started a problem like this after 7 years. Happens weekly.

the problem is the line is freezing up due to obstruction or blockage. which causes the water to back up and freeze, I have used a blow dryer, hot water, and a soft type long tiny tube or cord like material and even a coat hanger but be very careful, to get inside the line and unplug the obstruction or if u can remove the whole line and replace it? but may be very difficult. why was it pluged? some times pc's of plastic bags, old food particles, etc get into the line, doesnt take much

your first idea is probably the fastest. Hair dryer.
That's what I'd do no need to make it work overtime to cool back down.

Thaw it out with hot air maybe a hair dryer don.t use flame and hope it did not freeze bad enough to break something.

Good luck

The defrost drain outlet is stopped up and freezing over.
Remove the bottom basket.
Turn the freezer off.
Look in the center of the freezer just below the cooling coils in the bottom of the freezer.
You will see a water drain trough.
It will be full of ice.
Use a hair dryer to thaw the ice and remove it.
The drain will become exposed.
It must be thawed also,so that you can pour water through it and the water goes all the way to the drain pan underneath.

This could be a frozen water line that feeds the ice maker. Turn the temperature down on both the freezer and the refridgerator and wait at least 48 hours for the temps to adjust and thaw the line. If you are in a hurry you could turn off the unit and remove all food and then use a hair dryer on the water line to thaw it out. Good luck!

Hair dryer is the easiest way to thaw. To find cause: Remove lower grill and disconnect the water line going through the freezer door hinge. Usually it is a push lock fitting, which requires you to push the ring on the end of the fitting toward the center of the fitting while pulling (not hard) on the plastic tube. Now place a pan under the separated plastic hose and try the water dispenser. If water comes out, your problem is a frozen water line in the freezer door. A warmer freezer temp may help, or you can order and install a WR49X10173 water tube heater. (the heater may take 24 hours to thaw the line, but I have used it successfully several times. Cost about $50) If no water comes out the separated tube when you try to dispense water, reconnect the tube at the hinge by pushing the plastic line back into the fitting. Now, at the back of the refrig., disconnect the water line going from the water valve to the fresh foods compartment. Try to dispense water. No water at valve outlet = bad valve. Water dispensed from valve now = frozen water filter or water line at back bottom of fresh foods compartment. (make sure you disconnect the right tube. If in doubt, disconnect them both, just get them back correctly so your icemaker continues to work) Send me additional comments if needed. Don't rate before you try all the steps.

If water filter or water line/ reservoir is frozen, thaw with a hair dryer. If reservoir is frozen, check to make sure there is no frost on back wall of inside freezer, preventing normal air flow, allowing cold air to enter fresh foods compartment through return air vent at lower back of fresh foods compartment, resulting in freezing of water line / reservoir and possibly food in bottom bin.

Don't keep using a hair dryer ! Order the dispensor heater kit , pt # WR49X10173 . It comes with complete instructions for installation , so you can spend more time with the family .

If the temp in the fridge is to cold the water tank inbehind the crispers might be frozen, if so use a hair dryer to thaw, also if there is a water filter replace if its more than a tear old

GO TO THE FREEZER PORTION OF THE FRIG.YOU NEED TO TAKE THE ICEMAKER OUT AND REMOVE THE BACK PANEL WHERE THE EVAPORATER FAN IS .RIGHT UNDER THE COIL YOU WILL SEE A DRAIN ,WHEN YOUR FREEZER GOES ON DEFROST THE WATER GOES DOWN THE DRAIN AND INTO A PAN THAT SITS ON TOP OF THE COMPRESSOR.THE HEAT FROM THE COMPRESSOR EVAPORATES THE WATER.THE DRAIN IN THE FREEZER IS PROBABLY CLOGGED OR FROZEN OVER WITH ICE AND THATS WHY THE WATER IS GOING ELSEWARE.REMOVE ALL THE ICE FROM AROUND THE DRAIN.IF THERES A ROD THAT GOES DOWN THE DRAIN FROM THE DEFROST ELEMENT THATS SUPPOSED TO KEEP THE DRAIN FROM ICING UP ,IN ANY CASE THE DRAIN IS CLOGGED OR ICED UP.UNCLOG THE GRAIN AND YOU WILL BE GOOD TO GO.

try using a hair dryer to thaw out the trough and remove the ice. please note the ice will run all the way up into the tube where it comes thru the cabinet.
this may have occured from your recent filter change as a new filter introdues alot of air into the water system and will cause these tubes to freeze up. in the future right after you replace your filter be sure to run aout 1/2 to 1 gallon of water thru water dispenser to clear air out of system. thx peyton
