Norcold Refrigerator too cold

While getting our now three year old camper ready this season, I turned on the refrigerator (using electricity) for 48 hours to make sure everything was working right. This year, I noticed some frost building up on the fins. So I put a thermometer in it and a bowl of water and waited 24 hours. The temp was 20 degrees and the water was frozen. So I did some research and most of what I read from others with the same problem, indicated that it might be the thermister/thermostat that had gone bad and they solved their problem by buying a "Snip the Tip" adjustable thermister. I did that, installed it following the instructions and now my refrigerator's temp is 25 degrees at the cool setting and 22 degrees at the coldest setting. That's not much difference between the coolest and the coldest settings. Either setting is still freezing our food. Does anyone know What else can I check or replace to try and fix my problem? Thank you in advance for your replies.

It's a Norcold N611 unit. There isn't any adjustment knob to make it colder or warmer. Must be the basic Norcold Refrigerator.

Are you positive the Snip and clip aftermarket Thermister system will work with a Norcold? Remember, your Norcold DOES have a Thermister temp adjustment. The Snip and clip aftermarket replacements are designed for the Dometic Auto temp type refers. So, you have installed an additional adjustable tstat system in conjunction with the existing adjustable tstat system. IMO, that is incompatible. Just go out and purchase the CORRECT Thermister for your Norcold and install as the OEM intended. When I have experienced your type problem, just replacing the Thermister fixes the problem 100 percent of the time(at least 20 times over the years). Also, a defective Thermister will OHM test as good. This is why searching the Internet for a fix, sometimes, does NOT result in a good outcome. Doug

Should add if connection IS bad and you only snip the tip it'll still over cool till thermistor has a good connection.

Yes you can replace the thermistor but first... trace yours to the control board. Unplug and replug. If thermistor is failed open or loose or corroded the board will call for full time cooling.
