Hollow ice cubes are usually caused by a couple of reasons such as low water pressure, high freezer temperature, or a clogged water filter. Here are some steps you can follow to fix hollow ice cubes on a refrigerator ice maker:
- Check the water pressure: Check the water pressure going into the fridge by turning off the water supply valve and disconnecting the water line from the back of the fridge. Hold the water line over a bucket and turn on the water supply valve to check the pressure. The water pressure should be between 35-120 psi. If the water pressure is low, you may need to adjust the water supply valve or hire a plumber to check your home’s water pressure.
- Check the freezer temperature: Make sure the freezer temperature is set between 0-5°F (-18°C to -15°C). If the freezer temperature is too high, the ice cubes will not freeze completely, resulting in hollow ice cubes.
- Check the water filter: A clogged water filter can reduce the water pressure going into the fridge. Check the water filter and replace it if it’s clogged. Refer to your refrigerator’s user manual for instructions on how to replace the water filter.
- Check the ice maker settings: Check the ice maker settings to make sure it’s set to produce solid ice cubes. Some ice makers have an option to produce hollow ice cubes, which may be selected accidentally.
- Clean the ice maker: If none of the above solutions work, try cleaning the ice maker. Turn off the ice maker and remove the ice bin. Clean the ice maker with a solution of warm water and mild detergent. Rinse thoroughly and allow it to dry completely before turning the ice maker back on.
By following these steps, you should be able to fix hollow ice cubes on your refrigerator ice maker. If the problem persists, you may need to contact a professional technician to diagnose and repair the issue.
