We have a Jenn-Air Luxury Series Built-In refrigerator. It's a model from 2002. Even though it is 7 years old, it is nearly new as if spent most of it's life in a warehouse after it was reposessed from an appliance dealer and only used as a floor model by them. We recently plugged it in to use it and find that it runs continuously. Everything seems to be working fine besides this. All of the temperatures are at correct levels, etc. What do you think the problem might be? Thanks so much.
