The supply valve controls the flow of water to the refrigerator’s ice maker and water dispenser. If the valve is not fully open or if there is an issue with the valve, it may result in insufficient water flow, causing small ice cubes or no ice at all.
Caution:
Please read our safety information before attempting any testing or repairs.
Before checking the supply valve, unplug the refrigerator to avoid an electrical shock hazard.
Steps to Check the Supply Valve:
- Locate the Supply Valve:
- The supply valve is usually found under the kitchen sink or behind the refrigerator.
- If it is located behind the refrigerator, you may need to move the appliance away from the wall to access it.
- Inspect the Valve:
- Ensure the valve is fully open. Turn the valve counterclockwise to open it.
- It is recommended to open the valve just enough to provide adequate water pressure, rather than opening it fully, to avoid any potential issues.
- Inspect the Supply Line:
- Check the supply line for any dents, kinks, or pinching that could restrict the flow of water.
- If the supply line appears damaged, it may need to be replaced.
- Test the Water Flow:
- With the valve open, you can test the water flow by disconnecting the supply line from the refrigerator and placing the end into a bucket.
- Turn on the valve and observe the flow of water into the bucket. The water should flow steadily and with sufficient pressure.
- If the water flow is weak, there may be an issue with the valve or the plumbing.
- Check for Leaks:
- While the valve is open, inspect for any leaks around the valve and the connections.
- If you notice any leaks, tighten the connections or replace any faulty parts.
- Reconnect the Supply Line:
- Once you have confirmed that the supply valve is functioning properly, reconnect the supply line to the refrigerator.
- Ensure the connection is secure but do not overtighten to avoid damaging the fittings.
- Restore Power:
- Plug the refrigerator back in and move it back into place.
- Allow the ice maker to cycle a few times to check for proper ice production.
By following these steps, you can ensure that the supply valve is providing adequate water flow to the ice maker, which is essential for proper ice production. If you continue to experience issues with the ice maker, further troubleshooting of other components may be necessary.
