Dometic Fridge

My experience with Dometic has been good. Mine is the auto temp set, with sliding fin adjustment. Moving the thermistor on the fin will only change temp a small amount. I think you may have had other issues, with your Dometic fridge. It may have been operated off level at some time, causing partial plugging of tubes, which would keep it from cooling properly.

I've owned both Norcold and Dometic fridges of various sizes and neither works any better or worse than the other. That slider is intended to make only a minor temperature adjustment - if your fridge doesn't cool properly then it has other issues. I certainly wouldn't let the fridge make / model prevent me from buying any trailer I otherwise much preferred.

If it gets cold enough with the thermistor unhooked, replace the thermistor. Many recommend the snip the tip replacement, which has an adjustment on it.

I have that issue too. Replacing the unit with another Dometic but a compressor fridge, CR series. Absorbtion fridges mine be 'peachy' for the Amish but for me, they suck.

Thanks for the replies. We had a Dometic in our Cruiser 5th Wheel, we tried everything. We did the snip the tip mod, we put 2 12v fans behind the unit facing up across the coils, we tried putting in a potentiometer, nothing worked on getting that fridge below 40. Unplugging the thermistor was the only solution...it puts the unit in protect mode and buries it temp wise...we had to do this when camping to keep anything cold and safe for eating. When our trip was over, we'd plug it back in when it was in storage. I was hoping that they are better now b/c the units we like (Jayco's) are no longer using Norcolds.
