Norcold 1211 refer not cooling

I know there are experts on here who will probably have experienced this problem and fixed it. A couple of days ago I came home and the ice cream in the freezer was soft. Right away I realized something was wrong. At that time I also noticed that the fans were not running. They run continuously since new so I know there may be something to do with that as well. I have had the mobile service tech out and he has checked most of the apparatus but has not come up with the solution. The heating elements are heating, there is 12 VDC to the board, there is 12VDC going into and coming out of the safety gizmo beside the board and the led on the safety gizmo is not lit which the tech said meant it was okay. The temp set button, when pressed, flashes for 10 seconds which the manual says only that it indicates a fault that is not owner serviceable. Since the problem was first found, the fans came on for a short period of time but went out again. After being set at the coldest setting, 9, the two top freezing compartments have cooled down to 3F and 4F degrees but the cabinet is still near 50F. At the techs suggestion I have unplugged the thermistor to see if this makes a difference. So far it has not. Filling the bottom shelf of the cabinet with dry ice provides some cooling but I need a proper fix.
I'm in the Texas Rio Grande Valley experiencing 90 degree temps so solving this is paramount. Any thoughts on his a agonizing problem?
Thanking you in advance for your feedback.

  • I was hoping to get it working before I flew back home to Vancouver Canada but that will not happen now. I will have to revisit the problems when I fly back to get the coach and heard up into the Texas Hill country for the wild flower season which they claim will be superb this year. Thanks everyone for your feedback.

  • Get it back in fro warranty repairs.
    Let them fix the fans, check thermister (replace if needed) and insure cooling unit is working.

    Otherwise....as suggested. Fans need to be working & thermister checked.

    Without the fans working it won't cool properly. That is for sure
    Even if it isn't in a slide out the fans need to work. [COLOR=]I tend to agree
    They are controlled by a snap disc t-stat clipped on fin of upper condenser. I note same on the wiring diagram but cannot see it.
    The t-stat turns them on at 130*F and off at 115F.....condenser tube temps.

    Also from what I have recently been told the cooling unit may have failed due to blockage. Blockage in tubing after the upper condenser will allow freezer to cool properly but not allow the food section to cool off. Norcold believes it is not the cooling unit

    Is there the same lack of cooling on electric and propane? I've only been on AC

    Temp set button pressed........flashes for 10 seconds means fridge has swapped to 'Backup Operating System' which maintains fridge in operation when the thermister has failed (or been disconnected). I assume this happened prior to you unplugging thermister??? Yes, it was one of the first things I noted

    Get those fans in outside compartment working (jumper out t-stat and see that they work). Then replace t-stat. I have not found the thermal switch yet nor can I see the fans and a splash of water. Wait a couple of minutes and check resistance via connector at light---two bottom slots. Resistance at 32*F should be 30,000-32,000 ohms) Replace thermister if test bad. I will preform that test. Thanks

    If after those repairs and food section still does not cool down the cooling unit has blockage. Which means cooling unit replacement

  • Sounds a lot like our problem, except that we're in Mexico! At least you can get parts and a tech! (Though having Doug around is very nice.)

    Test thermister by placing it in a glass then pack it in ice and a splash of water. Wait a couple of minutes and check resistance via connector at light---two bottom slots. Resistance at 32*F should be 30,000-32,000 ohms) Replace thermister if test bad.
