Homeowners can prevent ice makers from freezing up by increasing the temperature of the freezer to the recommended level as designated in the appliance's manual. Routinely clearing the bin of large cubes stuck in the dispenser can also help prevent blockages and over-freezing.
When an ice maker does freeze up, the most common fix is to unplug the refrigerator, remove the ice bin, locate the fill tube that delivers water to the ice maker, and warm the hoses with a blow dryer. It may also help to warm the hoses by applying a hot cloth to the area to melt the ice.
When warming the frozen hoses, drips should be wiped up to avoid interaction with electrical components of the freezer. To avoid melting, the plastic parts should not be exposed to hot air.
