Appliances have to be tracked by individual models. Few brands are made exclusively in the USA, no matter how much PR says otherwise.
It is my opinion having recently replaced several appliances that Whirlpool appliances are American made.
When searching for a refrigerator, We went to Home Depot for the Veterans Day sale. They had moved 5 of the side by side refrigerator /freezers into a row for easy comparison. It turns out though having different brand names, all were made by whirlpoo companies. The warranty registration was made via the Whirlpool on line customer service site.
The unit we bought was cosmetically nearly to the 26 year old same brand replacement.
