The steps for cleaning an ice maker in a refrigerator door are generally the same, regardless of the manufacturer. Ice makers should be cleaned and sanitized regularly to avoid cloudy ice that forms in odd clumps and smells or tastes bad.
To stop the machine from making more ice during the cleaning process, lift up on the power bar. If the ice maker doesn't have a power bar, check the back of the machine for an on/off switch, or simply unplug the refrigerator.
Depending on the type of refrigerator, lift the ice storage bin up and out, or pull it straight forward. Empty the ice into the sink, and wash the ice bin with warm water and dish detergent. Once it is clean, sanitize the ice bin by placing it into the dishwasher and running the sanitizing cycle. Check the underside of the ice bin or the refrigerator manual to make sure it is dishwasher safe. Once sanitized, wipe the ice bin completely with a dry rag, removing all water.
Wipe down the ice maker unit inside the freezer with a soapy rag. Use a dry rag to wipe off any excess water on the unit. To sanitize, create a solution of 1/2 cup of bleach to one cup of water, then soak a rag and wipe down the ice maker inside the freezer. Again, wipe the unit dry to ensure that the unit operates properly. Slide the ice bin back into place, and start the ice maker.
