You folks on here keep saying if the control box is locked out, it would not work at all. That's not what Norcold says. I hope they know what they are talking about. I am really sorry I even made this post.

Don't be sorry. You posted a good info link. There is NO LOCKOUT other than the NO CO code. IF you had the NO CO code, then you have to do what is called a HARD reset. Disconnecting power will not reset the NO CO code. IF you have a NO CO code, the refer will not even function at all. It will just flash the NO CO code. From your post, your so called Technician is NOT qualified at all. Do not use him in the future for anything. Doug

Here is what they said!!!
The next step is to reset the Control Board. In the case of the two failures above, the problem was not the thermistor. The control board had locked-up. Based on information provided by a refrigerator technician, locking-up of the control board is a very random occurrence. It is believed to be caused by low house battery voltage, but may occur from other reasons. First, reconnect the electrical plug to the thermistor that was disconnected in the first step. Then go outside and remove the refrigerator ventilation panel. With the panel removed you should see a black control box mounted on the back of the refrigerator below the cooling unit coils. You will see many wires running to this control box. But, near the center of the bottom you should see a set of white and black wires connected to the box by spade connectors. The black wire is the 12 volt source wire and may have a smaller black wire connected to it, or it may be single. Disconnect the black wire(s) at the spade connector. You may need some needle nose pliers to do this. Caution, do not let this wire touch a ground source or other metal, because it is 12 volts positive hot. Leave disconnected for 2 minutes or longer. This in affect will reset the control board.

WHO said this? The website you went to or Norcold. The reason I ask, is, Norcold DOES NOT talk and give repair info to retail customers. They would never state such a thing to a retail customer. OLDER Norcold boards had such a problem and it was caused by a SLOW 12 volt drop in voltage. They fixed this problem on newer boards over 10 years ago. This is a different reaction from disconnecting 12 volts and re applying 12 volts. The reaction was caused by a slow discharge coming from a battery system going dead or dropping below 12 volts. Also, the wiring running to the refer is NOT always Black and White. On a 1200 there are also a Black and White that have the smaller wires connected also that is in the center of the control box and THAT set is for the rear fans and some interior control wiring. You have to be carefull what you find and apply from the Internet. I clicked your link and THAT was NOT an official Norcold site or bulletin. Doug
