How to clean ice dispenser The appears to have black mold????

wash it out with white vinegar

Need a professional for black mold

If you can take it out, dump the ice and clean it with bleach water and rinse it with vinegar and let that dry. The vinegar will take care of the mold or mildew spores that the bleach does not kill at all. With a flashlight or something check out what you can of the ice maker to see if it has any and clean it also in the same way.

Look up your refrigerator model on line if you no longer have the instruction manual. That will give you instructions to take apart to clean. Then follow Nancy's instructions.

Use vinegar in your water and clean very very thoroughly. Then rinse well. You might not want to use the first gallon or so of ice to be sure. Hope this helps.
