I have a Norcold 9163 fridge. When I set the fridge to have the temperature just above freezing the freezer will only drop to around 15 f. I recognize the unit only has one thermostat(thermistor) so you can't set the fridge and freezer independently.

I'm looking for ideas like increasing the insulation of the freezer or putting a curtain in the freezer so when you open the door all the cold doesn't 'fall out'.

Any suggestions??

A GOOD cooling unit will get the freezer BELOW 10 degrees. Now, If you are getting the lower section to 33 to 35 degrees, your temp measurement is not correct. A cooling unit that gets the lower section to 33 to 35, the Freezer will be BELOW 10 degrees, probably closer to 0. IF NOT, then the Thermal mastic between the freezer coils and the box of the refer is missing or inadequate. Do you know if the Cooling Unit has ever been replaced? Doug

I found that adding fans built into a mask at the top of the "chimney" provided for faster cool down. My fans are thermostatically controlled, and powered independently of the fridge. Temperature in the fridge part was improved, too.

Does your Fridge have an "Enviorment" switch or LAT switch (Low ambient temp)

This turns the light inside on even if the door is closed. The light is aroudn 15-20 watts of HEAT.. This makes the fridge run more.

Will it make the freezer colder? I truly do not know.

Of the five trailers (2-TT & 3-5ers) the only one that keeps Ice Cream solid it our current on with a Residential Fridge. All the others it was "Soft Serve Ice Cream" 15 to 18 degrees max

I agree. I installed a fan and it did iprove the temperature. I also have a battery operated fan inside the fridge to circulate the air. I do not have the outside fan set to a thermostat, but I would like to. I just put it on when it is warm and shut it off when cool. Just be sure it is secure. An old computer 12V or 120V muffin fan will do if you are handy. Just tie it to the proper voltage with a switch.

Thanks for the replies. I already have temperature controlled fans in the chimney and a battery operated fan in the fridge and freezer. I can get the fridge to be much colder but then it will freeze whatever I have in it.

Once again my question is how to get the freezer to be colder but NOT the fridge. I believe the solution will entail more insulation around the freezer compartment and possibly inside the freezer....just wanting your thoughts or suggestions.

Have you checked the condition of the door seals for the freezer compartment? I'd imagine an imperfect seal would cause a warm freezer (and more rapid frost build-up).

Another option is to get a separate freezer. If you have access to 120 volt power, I highly recommend this one. It will keep things frozen for 3.5 days without power, if it is full.

And of course there are 12 volt options, but they are more expensive :-).

RV freezers, if you buy the square/rectangle cartons of ice cream and store against the BACK wall of the freezer, it will get the Ice Cream harder. Doug
