Unplug it for 2 minutes to do a hard reset. If it does not reset check the temperatures with a thermometer if the temps are off by more than 5 degrees your temp sensors are out of range

Rhino, this is yet another simple fix. You need to call subzero and let them know that your ref section is not cooling properly. 9 out of 10 times it will be a problem with the evaporator coil needing replacement. Sub is aware of this issue and usually picks up the tab for this repair.

Call Samsung. I had the same problem when Best Buy delivered mine. The delivery people left the fridge in demo mode. The people at Samsung will talk you through it, it is very simple. The fridge should work fine then.

Make sure the thermister is attached firmly to the fins in the back. The boards on a Norcold can be reset a service center familiar with this process is your best bet. It takes disconecting the board and then shorting it out best to leave it to some one who is familiar.

The 37 degree reading you're seeing is the temp. setting, not the present actual temp. When it jumps back to 22-25 its telling you what the actual temp is inside the refrig....simply wait about 24 hours. It should then read about 37...that is, the temp you set it at 24 hours previously.

Sadly i would say the board is malfunctioning and needs replacement. There is nothing in the fridge/ freezer that if malfunctions can cause that.
