Do you own a Whirlpool or Maytag refrigerator?
While we cannot say with 100% certainty, it's entirely possible the Maytag refrigerator brand loves jazz & secret codes.
Whirlpool, KitchenAid & Maytag often use a control board called the "jazz board."
If you own a Maytag refrigerator built after 2010, there are good chances it has one of these jazz control boards inside
So their computer board is called a jazz board, whats the big deal?
A repair on these units require a secret code to program the appliance for cooling.
Actually the code is not that big of a secret (it's found on the model number tag) but it's unique within home appliance repair.
Failing to program the code however will cause the refrigerator to stop cooling. For many families -- thats kind of a big deal.
