Ice dispenser doesn't work
- Dispenser control board
If the ice dispenser is not functioning at all the most likely cause is going to be the dispenser control board. The dispenser control board governs the major portion of the systematic functions of the dispenser and is less likely to be the issue if only certain components are malfunctioning. If the dispenser control board is at fault, it will need to be replaced.
- Water inlet valve & low water pressure from house supply
If the ice dispenser on your refrigerator is not working properly, one of the first things to consider as an issue is the water pressure to your appliance. The ice dispenser cannot properly function with a psi less than 20. If psi is appropriate, proceed to replace the water inlet valve to correct the issue. You may also be dealing with low household water pressure. This low flow can be examined by using a water pressure test gauge. Once the household water pressure is resolved, you can double check your refrigerator connection to ensure it is now flowing properly and that the ice dispenser is functioning.
- Water tube in door is frozen
If the ice dispenser is not working on your refrigerator, the issue could be a frozen water supply tube located in the door. Although this may be a tricky problem to locate, the first thing to do is find a connection point in the tube. After this has been found, attempt to blow air through the tube. If the air flows freely through the tube, it is not frozen and this is not the issue. If it does not, the tube is frozen and needs to be removed to thaw out. As it thaws, attempt to ascertain why it froze and correct the positioning of the tubing to prevent the issue from occurring again in the future.
- Dispenser switch
If the refrigerator ice dispenser is not working properly you could be dealing with a defective dispenser switch. Activated by the dispenser actuator, the switches are responsible for numerous actions including ice cube disbursement, type of ice, and water controls. The switch can be tested using an ohm meter and should be replaced if it does not reveal continuity.
- Door switch
If the refrigerator ice dispenser is not working, the functionality of the door switch can be inspected. This switch is responsible for turning on the light in the freezer and simultaneously turning off the ice dispenser when the freezer door is opened. If this switch malfunctions, it will show no continuity on the ohm meter and will require replacement. Appliance Repair Help Troubleshooting and Appliance Parts
