There are a few different ways that you can find the error code on your KitchenAid refrigerator. The first way is to check the display panel on the front of the fridge. The display panel will usually have an error code that you can reference. If the display panel does not have an error code, you can check the manual that came with your fridge. The manual should have a list of error codes and what they mean. If you still can't find the error code, you can contact KitchenAid customer service for assistance.
