Top 7 Reasons Refrigerator Dispenser Isn’t Working?

Common solutions for: Refrigerator water dispenser not working
01 - Water Tube in Door is Frozen
To determine if the water supply tube is frozen, disconnect the tube at the bottom of the door and blow air through it. If air does not pass through, this indicates that the water supply tube is frozen. If the water supply tube is frozen, thaw it out. In addition, ensure that the freezer is kept at the proper temperature. The freezer temperature should be kept from 0 to10 degrees Fahrenheit (-18 to -12 degrees Celsius). If the freezer is too cold, the water line may freeze.

02 - Water Inlet Valve
The water inlet valve opens to supply water to the dispenser. If the water inlet valve is defective, or if the water pressure is too low, the water valve will not open. The valve requires at least 20psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to test the water inlet valve for continuity. If the water inlet valve does not have continuity, replace it.
The home may have insufficient water pressure. The water inlet valve requires strong water pressure to supply water to the water dispenser. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.
Highly Likely
04 - Misaligned water filter
Water filter may not be seated properly. Remove and reinstall the water filter. For optimal performance, refrigerator water filters should be replaced every six months or after 200-300 gallons (760-1150 liters) of water have been dispensed - whichever comes first. Replace the water filter if needed.
Highly Likely
05 - Home's water supply valve not fully open
The refrigerator is connected to a water supply valve that may not be fully open. If the water line was disconnected or the valve was shut off for service, it may not have been turned back on to the fully opened position.
Highly Likely
06 - Kinked Water Supply Line
Pull out the refrigerator and confirm the water supply line is not kinked. A kinked water supply line will cut off or reduce the water supplied to the refrigerator. It is best to replace the water line if it looks damaged.
Highly Likely
07 - Door Not Fully Closing
Check to see that the doors are closing properly. If a door bin or food item is keeping the door open slightly the refrigerator may not cool properly, which can cause the refrigerator to run constantly.
Common
08 - Water Dispenser Control is Locked
The ice and water dispenser will not work when locked (check for a lock symbol on the control panel). If the control is locked you will need to press and hold a "lock" button or another combination of buttons for 5 to 10 seconds to unlock the control.
Common
09 - Door Switch
The door switch turns off the ice and water dispenser when the refrigerator door is open. If the door switch fails, the dispenser will not turn on. To determine if the door switch is defective, use a multimeter to test it for continuity. If the door switch does not have continuity when activated, replace it.
The dispenser paddle actuator has a micro switch which sends voltage to the dispenser when actuated. If one of the dispenser micro switches is defective, the dispenser will not work. To determine if a dispenser switch is defective, use a multimeter to test each switch for continuity. If a dispenser switch does not have continuity, replace it.
