When the outside air temps increase YOU have to turn up the temp setting to '4' or '5'
I have found this to be true of my krappy Norcold as well but I don't understand it. If the fridge is using a "thermostat", why do we have to change the setting when the outside temp changes???
This is one of the things that's keeping me from doing a compressor conversion; I'd have to keep that stupid thermostat.
You turn COLDER to make the refer run longer in a cooling cycle. Sounds crazy, but it is the nature of RV refers. You would think if the refer can keep up at setting 3, it is obviously running and trying to get to temp, then why set at 4 or 5. I have no idea, but that is how it functions. Doug
PS, my theory is, it catches up at night and because it starts out in the morning COLDER, then it keeps up better thru the heat of the day.
I would never have guessed anyone would make a stat work like that but your theory explains everything that goes on with these things.

On '3' it can keep up when ambient temps are below 80*F
As temps rise Longer heating cycles (more cooling) is needed
That is why you have to turn the temp settings up
Thermostat is calibrated for range of 34*F--46*F based on temp setting with feedback from thermistor (which measures FIN temp and is 10*F colder then air temp)
All this together PLUS the Draft across backside of fridge make an absorption fridge function
