If your refrigerator dispenser is leaking water, start by inspecting the dispenser door for broken or misaligned parts, since a damaged dispenser door is the most likely cause of a fridge water dispenser leaking. If the door looks good, check the house water pressure at the kitchen faucet because low water pressure can force the inlet valve or dispenser to drip. Next look at the dispenser actuator and the dispenser switches; a worn actuator may not fully engage the switch and a bad switch can let water run when it should be off. Less commonly the water inlet valve itself is the culprit, especially if its solenoids are stuck or the valve fails to seal; the valve needs about 20 psi to operate correctly and can be tested for continuity with a multimeter.

01 - Refrigerator Dispenser Door
The dispenser door is opened by a motor or a solenoid to dispense the ice, but if the door is broken, it may not open properly in order to release the ice. You should inspect the dispenser door for damage to determine if the component should be replaced. You may have to remove the dispenser control panel or frame to access and inspect the dispenser door.

The water inlet valve, which supplies water to the refrigerator water dispenser, requires sufficient water pressure to work properly. If the water pressure is too low, the dispenser will leak. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.

03 - Refrigerator Dispenser Actuator
The dispenser actuator is the component that activates the switch or switches to send voltage to the dispenser. If the dispenser actuator is damaged, it may be unable to activate the switch. Inspect the dispenser actuator for any damage and replace with a new one if necessary.
A refrigerator water inlet valve will direct water to the dispenser as well as the ice maker fill tube. If the inlet valve is obstructed, the solenoid coils on the valve are defective, or the home's water pressure is too low, the water valve will not work properly. 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 dispenser switches send voltage to the dispenser. If one of the dispenser 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.
