Also the norcold guy said no fans on this model as it is an absorbent type , not sure what he means?
Absorbent......
RV fridges are absorption fridges. No compressor. Cooling fluid (ammonia, hydrogen, sodium chromate) is heated and turns into a vapor the vapor absorbs heat from freezer/food sections, condenses back into a liquid as it flows by gravity down thru cooling unit where it is heated again and repeats process.
The 1200 Norcolds have fans in outside compartment (top) to help pull air thru/across cooling unit.....especially when installed in a slide.
Fans are just a means of increasing/insuring enough air circulation for proper heat transfer.
Your model (and many others) use natural draft (like a fireplace chimney) for air circulation from bottom vent up/thru top vent.
Unplugging the thermistor (temp control) causing fridge to go into continuous cooling mode.
With thermistor unplugged and food section is still warm......blockage in cooling unit :E
