I CANNOT GET WATER THROUGH THE DOOR, HAVE WATER TO THE LINE AT THE BOTTOM OF THE DOOR

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 . (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.
