User Suggested Solutions

  1. Check and clear the water supply line. Disconnect the refrigerator from power, locate the water supply line, and inspect for kinks or clogs. Use a wet/dry vacuum to clear any blockages if necessary.

  2. Test and replace the water inlet valve if faulty. Turn off the water supply and power to the refrigerator. Remove the valve and test it with a multimeter. If it shows no continuity, replace it with a new valve.

  3. Ensure the freezer temperature is set correctly. Use a thermometer to check the actual temperature in the freezer. If it's above 0°F (-18°C), adjust the thermostat and allow time for the temperature to stabilize.
