Amana side by side

It may very well be frozen. Some of those fridges have problems with the line freezing because of the way the line runs. The one way to tell would be to empty fridge, unplug, and let sit to thaw. Opening freezer/fridge doors will shorten the process. You can Google your exact model number also, and find out how your lines run and use a hair dryer on that location.

Had this happen on my LG side-by-side a few years back. It's a common part. Find the version for your make and model. Easy ti replace. It is located where the water suppy connects to the bottm refridge.

My water dispensor INSIDE the door froze up.
I payed a repair guy $75 to use MY BLOWDRYER to "thaw" the frozen water line INSIDE the freezer door (below the water dispenser).

He said anytime the frozen food extends over the freezer shelf and touches the freezer door for a long enough period of time, the water line inside the door FREEZES!!

PREVENTION: "Keep some airspace between the door and frozen food."

first run the diagnostics on the unit from the tech sheet inside the unit,then if thermistors are bad replace these there are 2 one on the left and one on the right wall in both fridge and freezer,if good per diagnostics then replace the electronic damper door located between the fridge and freezer compartments in the upper left hand corner of the fridge behind the plastic grille as these doors break and jamb open or shut and the temps can no longer be regulated during the diagnostics tests you can hear this door operate if its operating correctly,lastly,if these fail to solve your problem,replace the main control board in the back behind a panel

If the light and ice dispenser on the front panel works and If your fridge is 4 years old or older, the insulation in the freezer door has most likely deteriorated and the water in the tube feeding the water dispenser has probably frozen. Open the freezer door, put a blanket over the food to keep it from defrosting, and use a blow dryer to defrost the door. Blow the hot air on the flat panel inside the door (the backside of the water dispenser). Close the door about every 5 minutes to check to see if the water works. Once the water begins to flow, you have successfully defrosted the ice in the tube. Defrosting the door works for about 12 hours until it freezes again. To solve this problem, I placed a 10" weedeater line up thorugh the dispenser nozzle leaving about 1/8 of an inch sticking out. When the line freezes again, pull out the weedeater line, dispense water to free the ice, and then reinsert the weadeater line. I keep the line in all the time...it works great! If the light or ice dispenser do not work, the problem may be *********** board.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

Remove the bottom kick plate . Follow the plastic line about 6" and you'll find a connector . Push in on one end of the connector and at the same time , pull the line out . Close the door and press for water . If no water comes out of the disconnented line , the water valve is probably bad . If water does come out , the line inside the freezer door is frozen . If this turns out to be so , you can lower the freezer temp for maybe days , or , put the food on the door, inside the freezer , tape the light switch down ( to keep the lite off and fan running ) and tape plastic over the freezer door opening so the freezer will continue to work . Reinstall the line back into the connector by pushing the hose firmly into place . Leave the freezer door open for maybe 1 or 2 days for thawing out , going by ocassionally and pressing the water dispensor . Important : lower the freezer temperature slightly to keep line from freezing again . ONLY CHANGE THE FILTER WHEN WATER FLOW SLOWS OR ICE CUBES GET SMALL . The change filter lite comes on by the amount of times water dispensor is used and to make money for the vendor .

turn freezer side to zero for 1 minute press water dispenser

if you can get ice but not water from the dispenser then suspect a frozen water line within the door . Check you get water to the connector at the bottom of the freezer door. Sometimes you can clear the blockage by connecting a steamer to the pipe but this will only be a temporary fix . If the pipe has frozen within 6 inches of the dispenser outlet then there is a heater mod that can be fitted WR49X10173

More than likely, your water line is freezing up in the door. You can remove all of the ice cubes and lower the freezer temp to about 3. Leave the freezer door open for about 5 minutes or so and if this does not work, leave the door open a little longer. Also, disconnect the water line at the base of the freezer door, near the floor, and press the dispenser lever. If you have water there, you most likely have a frozen line in the door. Changing the water filter often will help but it is not the answer and is can get quite expensive. By the way, Make sure to hold the dispenser lever forward for at least a couple of minutes each time you test for water flow. If you do not get water at the connector at the base of the door after you have disconnected the line, you have a problem with the valve in the back of the refrigerator.
