A persistent odor in your ice from a refrigerator ice maker can be caused by a few different factors. Here are some possible reasons for the smell and suggestions on how to address them:
Stagnant water: If water sits in the ice maker for an extended period, it can develop an unpleasant odor. This can happen if the ice maker isn't used frequently or if the water supply to the refrigerator has issues. Try using your ice maker more frequently or turning off the ice maker and emptying any existing ice regularly.
Contaminated water supply: If the water supply to your refrigerator contains impurities or has a high mineral content, it can contribute to an odor in the ice. Consider having your water supply tested for impurities or installing a water filtration system to improve the quality of the water going into the ice maker.
Dirty components: Over time, the ice maker's components, such as the ice bin or ice chute, can accumulate dirt, mold, or bacteria, leading to a foul smell. It's important to regularly clean these parts using mild soap, warm water, and a soft cloth. Pay close attention to any hard-to-reach areas or crevices where dirt can accumulate.
Faulty drain system: Some refrigerators have a drain system that removes excess water from the ice maker. If the drain is clogged or not functioning properly, water can accumulate and cause a smell. Check the drain system for any blockages or malfunctions, and clean or repair it as needed.
Poor ventilation: Inadequate airflow around the refrigerator can result in a musty smell in the ice. Ensure that there is sufficient space around the refrigerator for proper ventilation. Additionally, periodically clean the condenser coils at the back of the refrigerator to improve airflow.
If you have already replaced the ice maker and regularly changed the filter, it's worth investigating these other possible causes. If the issue persists despite your efforts, it may be helpful to consult a professional appliance technician who can diagnose the problem more accurately and provide appropriate solutions.
