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.
