Water & ice dispenser

Three things could be wrong:
Solenoid switch where the water comes into the unit has gone, this control the flow of water into both the ice maker and the water dispenser.
If the switch is good and then you need to check your filters, sometimes inside the door top right. or on one of the corners on the bottom front.. You should be able to unscrew them with you hands.. make sure water is off behind unit or where ever your shut off is at.
One last thing.. check for kinks in the water line behind the unit if it was pulled out lately.

If the refrigerator water dispenser is not working the water supply tube in the door may be frozen. This will be difficult to track down. Look for a connection point at the bottom or top of the door, try removing the hose and blowing air through it and out the dispenser. Next it could be the water valve that sometimes has twin valves for ice and water combined, third is low pressure into the line (bad main valve) or clogged filter... you need about 20psi for function. Last is the door switch, when the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice and water dispenser. If the door switch fails the dispenser will not turn on. The switch can be checked for continuity with an Ohm meter. If it doesn't have continuity it should be replaced.

If the refrigerator water dispenser is not working correctly the water supply tube in the door may be blocked. This will be difficult to track down. Look for a connection point at the bottom or top of the door, try removing the hose and blowing air through it and out the dispenser. Next it could be the water valve that sometimes has twin valves for ice and water combined, third is low pressure into the line (bad main valve) or clogged filter... you need about 20psi for function. Last is the door switch, when the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice and water dispenser. If the door switch fails the dispenser will not turn on or may just dispense one item. The switch can be checked for continuity with an Ohm meter. If it doesn't have continuity it should be replaced.

If the refrigerator water dispenser is not working correctly the water supply tube(s) may be blocked. This will be difficult to track down. Look for a connection point at the bottom or top of the door, try removing the hose and blowing air through it and out the dispenser. Next it could be the water valve that sometimes has twin valves for ice and water combined (this is most likely the culprit) , third is low pressure into the line (bad main valve) or clogged filter... you need about 20psi for function. Last is the door switch (try this first), when the freezer door is opened the freezer door switch does two things, it turns on the light in the freezer and turns off the ice and water dispenser. If the door switch fails the dispenser will not turn on or may just dispense one item. The switch can be checked for continuity with an Ohm meter. If it doesn't have continuity it should be replaced.

replace the water valve and clean the coils undrer neath . ( make shure the fan under is working . mm

check the door in the dispenser if moisture is condensing and freezing so that the door won't open try manually popping the door open just before you attempt to dispense ice, maybe you'll get lucky, otherwise your going to have to get a technician to come and check the micro-switch for the dispenser

If you can't hear the solenoid on the water inlet valve(it's on the back where the water supply hooks up) when you try the water then the water switch on the dispenser is at fault.

If you do hear it Your water line could be frozen in the door. You can disconnect the line under the unit before it goes into the door at the bottom hinge. Push the dispenser button and see if it comes out there. If it doesleave the door open till it thaws.

If it doesn't come out there disconnect it at the water inlet valve and see if it comes out there.

change your water filter its probably full of dirt and plugged

ALWAYS MAKE SURE YOUR APPLIANCE IS UN PLUGGED BEFORE TRYING ANY PROCEEDURES !!!!!! MAKE SURE THE WATER SUPPLY VALVE (SOMETIMES 1/4" SADDLE TYPE PEIRCING VALVE) IS NOT CLOGGED WITH SEDIMENT... THEN MAKE SURE THE WATER SOLENOID IS NOT CLOGGED AS WELL ... THE WATER SUPLY SOLENOID HAS A SMALL ORFICE THAT CAN BECOME PARTIALLY CLOGGED OR DOES NOT "SEAT PROPERLY" AND CAN CAUSE INSUFFICIENT WATER SUPPLY AND THUS ERRATIC OPERATION. A LARGE PERCENTAGE OF WATER DISPENSER AND ICE MAKER PROBLEMS ARE DUE TO INADEQUATE WATER SUPPLY. IT IS THE FIRST THING THAT NEEDS TO BE CHECKED !!!
