Refridge freezing food ... 2401w

I just started a 3 month, Ohio to CA adventure in my new 2401w and slowly learning how everything works, mostly. One problem however I can't figure out is why the refridge keeps freezing the food. I've tried adjusting that stupid sensor and nothing seems to work. Any suggestions?

Can you give us the fridge make and model number?

I assume it's a Dometic. Have you tried moving the thermistor over a few fins?
If it's not that, you may have a bad thermistor and the fridge is running in limp mode. Does it switch energy sources with the buttons?

Where is you thermostat on the wire in the back? Try moving it up. If it is down low hanging the fridge is trying to get the temp colder. Mine is on the back of the top shelf.

Refridge is still freezing food. I'm not sure how the thermostat fits into plastic mount. Is this correct.Click image for larger version

Yes that is it. Sliding the clip down is warmer up is colder. Make sure the thermistor is clipped into the small pocket in the slide as shown

So, does it look like mine is mounted correct or should only the tip be exposed. The plastic holder is down about as far as it goes.

Reposition the sensor in the bracket so the tip is even with the top of the plastic bracket. This will allow you more adjustment toward the bottom of the fins which will cause your frig to run warmer. It will work for you to move the sensor down, you'll just have to mess with it a bit to get your temp correct!

Your thermister is too high in the clip.
Only the very tip should show when positioned in the clip.
See the instructions in the photo Flybob posted.

Refridge freezing food ... 2401w

If you move the tip down into the clip where it belongs, that will be about an inch. Try that and see how it goes. If need be you can slide the clip with the thermistor down lower but try a bit at a time and give the refrigerator time to adjust. It's best to have a small thermometer in the refrigerator like this to keep a close eye on the temp:

Cooper-Atkins 330-0-1 Refrigerator/ Freezer Vertical Glass Tube Thermometer https://www.amazon.com/dp/B0041TJCB4..._gOU4xbF9MP6Y9

(I think you can find them cheaper. I got them for $2 each on Amazon last December.)

The control is backwards to our thinking. It's because warm air rises. Therefore higher up (in the cooling fins!) is actually warmer air which makes the thermistor think it's too warm and call for more cooling. Lower is cooler so the thermistor thinks it's colder so doesn't call for so much cooling. Weird, right?

Not sure what's weird about this. You move the thermistor in the direction you want the air measured so your refrig can correspond correctly.

It's backwards. One would not normally move a temperature control into the cooling fins to ask for more cooling. You would think it's colder up there, not warmer. At least I sure would. To ask for more cooling, I would move the controller out away from the fins into the middle of the box where I would think it is warmer.

Maybe it's just me, but the temp control on the Dometic fridge has a real redneck engineering feel to it...but it does work.

Works for some .... but still not me. Will be traveling through Minneapolis and on to Sioux Falls to register, etc this week so will have to stop and have a service center look at it. Hope it's an easy fix.

If you can stop at Shorewood RV, they really take care of the customer! They are on the north side of town outside of Anoka towards Ramsey. You would need an appointment for sure. They prefer leave and come back job, but will do some service while you wait if you make that clear when you make the appointment AND when you arrive.

I guess it's how you look at things as it makes perfect sense to me. I'm moving the Temp Sensor, not the Temp Controller! The sensor moved to a cooler place in the frig will call for less cooling, therefore, reducing the temp in your frig. It's not really Rocket Science. I think the issue is most likely some are viewing the temp sensor as a temp controller which is not the case. The TEMP SENSOR is simply providing info TO THE TEMP CONTROLLER which controls the temp.
