First, we located a schematic for the refrigerator and identified what the part was called. Then we hunted for someplace to buy the part and found appliance we actually found the two parts that we needed fairly quickly, ordered them online on a Saturday. Our parts were shipped Monday and arrive Tuesday. While reviewing the shipping documents, we found that instead of Maytag parts we were going to receive whirlpool parts! When I called in the polite and evidently knowledgeable person, explain that whirlpool had acquired Maytag and that the parts were interchangeable for this application. It was right. Once the parts arrived, we put them into the refrigerator and they fit perfectly.
