This ice cube mold and heater assembly has a flake resistant surface with separations that mold eight ice crescents and is used with modular style icemakers on some refrigerators. The mold heater is an electrical device that thaws the ice quickly, so it can be released from the icemaker mold. If your ice maker isn’t making ice you may need to replace this part. Please remember to disconnect the power and water supply before starting your repair.
