Here is the proper fix. You have a very special Norcold refrigerator that came with "Automatic" temperature control. It did not work. All the food in the lower section would freeze. Norcold will replace the Automatic Front Control Panel with the "Tried and True" older style if you call Norcold Tech. Services. They may ask you to work through a Dealer or Authorized Service Representative. The part and labor will be covered by warranty.
You will need to buy the correct Norcold thermister and get your thermister system back to the original configuration.
