I have just purchased a used 1999 motorhome with a Dometic model 2852 refrigerator ; there is no way to set the temperature in the refrigerator, the instructions say that the temperature is set at the factury. I have checked the temperature in the refrigerator and it checks to be approx 40 degrees in the middle shelf. In my other motorhome (that I sold) I could set the temperature, this one I can't (there is no temperature adjustment).
My question? if the factory can set the temperature, there must be an adjustment somewhere; I like my frigerator to be set at between 35 and 38 degrees. to me this one is a little high.
Does anyone know where this adjustment is?

If your refrigerator does not have a temperature adjust6ment on the front panel, it is preset without an adjustment. There is a thermistor on the refrigerator cooling fins, to detect the temperature. I do not know of any adjustable thermistor. You might be able to add a resistor, about 100,000 to 200,000 ohms, across the (parallel circuit) thermistor wires, and fool the board into thinking it is warmer than it is to provide lower temperatures. You may need to play with different values to obtain the preferred temperature.

If there is a thermistor attached to a cooling fin inside the fridge, try moving it up or down a little on the fin.

Like Gary said, move the thermistor up to cool more, down to cool less. If your frig is still too warm move the thermistor one fin left and begin again.

edit: note- the thermistor or capillary tube should not touch the fins.

Try the following link for a service tips manual for your fridge. http://www.bryantrv.com/docs2/docs/1252service.pdf This is a pdf file. I found it on the Bryant RV site under "service manuals". As long as you know the model number of your fridge you should be able to find the manual there. Hope this helps.

Look in the back, at the fins, You should see a white plastic clip with a wire going to it.... Slide it toward the top of the fin and see what happens to the temps

Or slide it down

The device in the clip is a temp sensor (Thermistor more than likely)

and the top of the fin is warmer than the bottom

So sliding it UP lowers the temp, and sliding it DOWN raises the temp, inside the 'fridge

Also you might add a fan, I use a computer type fan (12v) hooked to the light circuit
