Dometic RM 1350 Fridge cooling question

[hotdog26]

The fridge seems to work correctly on both gas or electric. Here's my question, the temp on the eyebrow says the fridge is at 33 deg. but the thermometers in the fridge read 40 and freezer reads 3 deg. So what's the problem the thermistor, eyebrow board or where is the temp sensor because I think the temp should be a bit colder. accepting all suggestions and ideas.

so no one knows what they are talking about. wow, what a rude reply for people that were trying to help.
dougrainer was correct, YOU did not ask correct question.
with your attitude, you might want to change your username if you post again.
also might want to apologize.
these are great people
good luck with future posts

Here is a update since no one that replied knows what there talking about. I talked to Dometic tech and they said that if the temp display on the front of the refrig was reading wrong it was probably the eye brow board.
Now here is what I did. I addressed the area in the top access panel and added a baffle that directed the flow of air over the top fins of the fridg. I also added a fan attached to to top outside vent 6 inch computer fan. Inside the fridg I replaced the thermister with a adjustable snip the tip. I also added a fan that attaches to the fins in the fridg. Last trip the fridg got down to 32 deg that never happened before. The freezer was -3. I havent put this to a 90 deg day test yet so we will see.

So, you state none of us know anything. So, what does the Refer digital display read when you state got down to 32 degrees? Also, what is the ACTUAL temp of a glass of water?. What you have done is make good MODIFICATIONS that will help your cooling if the refer was not installed to spec. But, to state none of us know what we are talking about is not correct. You did NOT ask how to get the refer colder, you asked what the display had to do with the refer. As I stated (correctly), it ONLY tells you what the Evap fins are and they will be colder by 10 degrees, unless Dometic has changed the design of that particular model's Thermister that will read the temp which would be 10 degrees warmer than the actual Fin temp. The Thermister on your model is connected to the evap fins. The more airvolume over those fins will indeed make for better heat/cold transfer. Doug

Lets take for granted that the thermometers are accurate the air temp in the fridge is 40 but the the temp showed on the outside of the fridge shows 33 where does that get its info from? I also have the old style metal round thermometer they are >1 deg apart.

Read my first post to get your question answered. Doug

Nothing is the problem other than possibly how you are measuring the food section compartment temp.

Thermometer in glass of water on shelf
OR
Thermometer hanging from a clip on the shelf

Measuring water temp is much more accurate method

If you want to check the accuracy of your thermometer, fill a glass with crushed ice and water then put your thermometer in it. If it is calibrated correctly, it will read exactly 32 degrees. This is the temperature that water freezes and ice melts, plus or minus latent heat that the thermometer can't read.

Not accurate and will not sense the correct temp for this type measurement. Both RVP and Dometic state to NOT use IR type thermometers for temp measurements. The BEST way to sense refer temp is with a cup of water after 24 hours and insert a digital thermometer.

First make sure your thermometers are correct. I had a refrigerator thermometer that was 10 degrees off.

The freezer has no temp sensor. The temp sensor in your model is the Evap fin sensor.; The evap fins will be 10 degrees COLDER than the actual temp, so at 40 degrees the refer is within spec. The ideal would be 23 to 27 degree readout which add 10 degrees to that reading. Are you at MAX cold (5)? Doug
