I have a Dometic DM2862 refrigerator unit. Turned it on last night. The freezer works great, but the refrigerator isn't cooling at all. Any ideas?

If the freezer is down to zero degrees it is working properly. If it is just freezing water it is not working OK. Refrigerators / freezers can take 24 hours or longer to cool all the way down. If you put some jugs of water in the refrigerator it will cool down quicker and hold its temperature better.

Can't tell you this from personel experience but an rv tech. once told me a fridge will cool down faster by running off of LP rather than AC.

Welcome to the forums. The refer section gets the cold that's left over from the freezer and often it takes 24 hours for the refer to get cold. For the unit to work properly, the freezer has to get close to 0 degrees (not just cold) and then the fins in the refer will get 27-30 which will get the rest close to 40. Putting frozen jugs of water in the refer section will speed this up. In that little Search box at the top is a lot of info like this when I searched for "freezer cold but".


This post is my opinion (free advice). It is not intended to influence anyone's judgment nor do I advocate anyone do what I propose.

What are the temps of each box after running overnight without opening the doors?

I have heard the same thing but hopefully I will gas back to our 6162 Norcold and I will test to see in our case if that is fact or fiction. I have my electric cool down times recorded.

I was trying everything out on my new TT this spring. It made ice cubes all right but the fridge was still warm. Then I noticed the thermistor was closer to warmer than cooler. Adjusted it towards cooler & everything was fine.

Unfortunately there is no mention of this in the Dometic manual that accompanies the fridge.

Would not just slipping the thermistor off make one go to MAX cold mode as a quick test to rule out cooling unit problems?
