Refig temp adjustment

[flyfishing48]

Our refrige has temp settings on the control panel above the freezer door. But inside is the slider clamped to the fins. This can be moved up and down. In my previous campers that WAS the temperature adjustment.
During our PDI they told us if we wanted the temp colder than the highest setting on the control panel we could get more adjustment by moving the slider.
I can't rember which way to move it to make the refig colder.
Anyone know which way to move it?
Thanks in advance for any help.

We could never remember which way to move the thermistor, so we wrote on the inside of the fridge with a waterproof Sharpie pen -- up is cooler, down is warmer. I would have written it in the manual, too, but I can never remember where it is . . .

WHY? If the Thermistor on both the adjustable and non-adjustable models read the fin temperature and the fin temperature is warmer at the top, why wouldn't moving the Thermistor on the adjustable models have an effect?
Inquiring mind want to know.

Thanks for your explanation of this phenonenom

Simple. The Adjustable Thermister senses the temp of the evap fins and sends an OHM signal to the control board. There are 5 temp measurements. Lets call them for simplicity 1-40 degrees, 2-38 degrees, 3 -36 degrees, 4-34 degrees, 5-32 degrees. The Evap fins will be 10 degrees colder than the actual temp of the items in the refer------If the fin temp is 26 degrees, the items if the refer will be 36 degrees and at THAT temp on selection setting (3) the fins will be 26 degrees, the items (refer ) will be 36. It makes NO difference HOW the Thermister senses that 26 degree fin temp. Once it sense's it, it will shut the refer OFF as the tstat has been satisfied. The Thermister does NOT sense the actual temp in the refer but the Evap fin temp. Moving the Thermister up and down on an Auto temp just means it runs longer to get the Auto temp thermistor to trip and shut off which means it will get colder on a hotter side of the fins. You can take either type Thermister OFF the Fin and let hang and the refer will operate at its fullest cold which usually means freezing items in the refer. This reminds me of my wife. She is adamant that at home, if she puts the Home AC at 60 degrees when the house is at 80 degrees, the house will get colder QUICKER to 72 degrees, rather than just setting it at 72 degrees and letting the AC do its job. The AC systems do not get cold quicker when you set the temp lower than you want:B Doug

I did move thermistor up just a little. As per what the service tech at our dealership said, it appears the refig is cooler. It's only been about 16 hours ago, so I'll watch it for a few days with various ambient temps and see what happens. As RLS points out it seems like it should have some impact, as this is the feedback to the controller telling it how cold the fins are.

The reason it makes no mention is because it is not a feature of your specific Dometic refer.
RM2351, RM2451, RM2551, DM2652 & DM2852. These are the Auto Temp refer models that sliding the thermistor will allow cooler or warmer lower temps. Models that you can adjust 1-5, sliding the Thermister will have no affect. Doug

Something I do...when I learn the right way to operate the refrig, I make a note in the manual so the next time I forget how I can refer to my note. LOL

Click here for what should be the manual for your model.

If you do not have a manual then consider printing the manual for future reference.

Hope this helps.

Make and Model does not make any difference. If you have an adjustable tstat, sliding it up and down will make no difference. If you have an Auto temp refer, then sliding it will change the temp by no more than 3 to 5 degrees. Dometic is the only brand I am aware of that had a subset of Auto temp models. Doug

Remember it this way.

North - colder (up)

South - warmer (down)
