You don't say your refrigerator model number. The solution would be different for different ice makers. I have the KitchenAid (same manufacturer) and mine went out. I found this troubleshooting guide (
https://www.whirlpool.com/content/da...09412-reva.pdf) that isolated my problem to a faulty ice maker. You can get a replacement here (
Appliance Parts Pros - Find Repair & Replacement Parts Online) as well as Amazon. Replacement videos are also at appliancepartspros as well as YouTube. It's a little involved, watch them and see if you're comfortable doing it yourself. You also could contact Hartman's Appliance Repair (
