Refrigerator Not As Cold As It Ought To Be

I guess I did not explain it correctly. The FREEZER has NO way to control its temp. It will get to 0 to 10 degrees regardless of the Temp set. The design of an RV absorbsion refer is such that the Freezer coils are the FIRST coldest section of the tubes. Then it goes down to the lower refer section. This lower section is what is controlled by the tstat. Both Dometic and Norcold operate the exact same way. This is what confuses novices. They buy a used RV and the seller shows how COLD the freezer is and they assume the refer is at operating spec. They go home and then find that the lower section does NOT get below 40 degrees because the refer is partially blocked. A defective/blocked refer will still get the freezer below 10 degrees because the blockage is past the freezer coils. If you are having a problem with getting the freezer below 10 degrees, then you either have a incorrectly sealed cooling unit to the box or there is a lack of the correct amount of Transfer Mastic on the freezer coils. That is why I asked if the Cooling unit had ever been replaced. Long shot would be a defective freezer door seal, but those are rare. Doug

I have a Norcold N811 which is about 3 years old, never rebuilt. Mounted in the slide. Currently 100 degrees outside 80 inside.

The freezer is at 6 degrees and the fridge is running 43. Temp selector is at 5. Sounds like fans are running. Have not visually confirmed. Added a small 110 desk fan blowing up inside the back of the unit - don't think it is helping. Last night the fridge got down to 31 but not the really doing well when 95+ outside.

Any suggestions?

Edit to add: I have a small internal fan (e-bay) blowing over the coils at the thermistor.
