Temp Regulation in Norcold Fridge
I have a 121X series Norcold fridge - 12 cu. ft. I think. It seems to do a poor job of regulating the temperature inside the fridge. For example: Note: All of these examples occurred without large ...

You're right about the fans, although the Norcold 1200/ 1210 does have two fans mounted at the top. If those fans aren't coming on at all and you're in a warm climate, you probably have either bad fans or a bad fan thermostat. You can get to the fan thermostat from the roof vent. Try bypassing it to see if you can get the fans to come on. If they come on, you know that the issue is your thermostat.
The fans seem to be working as expected, and we have not been in really hot weather. Highs in the mid-60's to low 80's.
Since my original post, the temp has once again risen to 43 and then dropped off to 34. As before, this happened with very little opening/closing of doors. It still seems to me that the thermocouple and/or control circuitry is just waiting too long to react to rising temps inside the box.
I called Norcold customer service, but gave up after being on hold a long time.
The ambient temps you're in aren't all that hot so it really should be working properly if your ventilation is done right (and most are NOT). You should post a couple of pictures to this thread of how your ventilation looks from the top vent straight on, looking down and then one from the lower vent looking up. The most important things are that you are forcing air across the condenser fins (the fins at the top of the cooling unit) and then that the hot air is being forced out of the upper vent. In a slideout with two sidewall vents, you may need a baffle angled in a half moon shape going from the back topside of the refrigerator to the top of the upper vent.
This doesn't sound like a board issue. If it's intermittent, it's more likely that the issue is with voltage or the thermistor.
Yes, I am "The Norcold Guy" from thenorcoldguy.com. That being said, we are NOT affiliated with them and certainly don't stand behind decisions made by the company. Seek Adventure, LLC is the company and we work on all RV refrigerators and air conditioners. Don't beat me up over any issues you have with the Norcold brand!
