Dometic RM2350 Fridge not cold enough (by 2 users)

I am going to first sugest to do a direct test on the cooling unit. You will first need to locate the 110Volt heating element on the rear of the refrigerator. It is located in the tin stack on the right hand side. After locating these two wires, you must plug them in to a 110 Volt source. You can do so by cutting an old extension cord and splicing the wires to to the heating element wires, then plug the extension cord in. This will by pass the thermostat and run your cooling system wide open. If your refrigerator works in a direct test then the problem is your thermostat. If you need any more info, please feel free to contact my company Arctic Cold Refrigeration @ 1888-782-6665 or by email matt@arcticold.com

I have an RV Travel Trailer with a Dometic RM2852, similar to yours. bottom line is Dometic refrigeraters are a piece of sh!t. They are overpriced junk.

Good news is that there are a few things you can try before you go insane with your Dometic. Some suggestions are posted here:

Also, you can replace the OEM electronic motherboard with a better made 3rd party board made by Dinosaur Electronics, who make quality replacement boards for about $130. They are not difficult to install.

I suggest that you also be aware that if the outside temperature is really hot and humid, your fridge will not get as cold as you may like, even on the max setting. But for the most part, the Dometic OEM electronics are cheap junk. The Dinosaur board is better, but you may even have to get a new cooling unit (evaporator/condensor unit). These cost about $400-500 on ebay, and they claim you can install them yourself, but I am a bit squeamish about taking apart a working fridge. You might want to hire an appliance guy to do this instead, unless you are a super handy guy.

My Dometic was so bad, that I was tempted to drill a big hole between the freezer comparment and the fridge compartment and put a rubber plug in it, so I could allow more cold air to drop down into the fridge compartment. That was, until we got the Dinosaur board, which made ours a lot better.

Get a good thermometer, too, so you can check your temperature in the fridge and freezer.

Good luck.
