Thank youThe freezer chills first, then (gradually) the fridge temp will drop. Also, where is your thermistor located presently? Slide it up to the top (of the metal fins) for lower fridge temps. Note: Even if the plastic thermistor holder is at the top, pull it off (the fins) and look inside the plastic slider... Is your thermistor at the top of the plastic slider? If not, just push it up until it is, then place the plastic slider back on the metal fins up towards the top.
Thank youThe Dometic we had in our old coach didn’t have the thermistor, just the setting on the panel for coldness.
We did add a couple computer fans to the air intake panel and had a couple battery powered fans in the refrigerator portion to help with air circulation.
The fans in the outside made a large difference to the overall operation and how well it cooled. Ice cream actually got hard in the freezer.
The above is correct, the first thing that will get cold when starting up is the freezer then you will notice the fridge portion getting cold.
One of the internal fans we used in the fridge portion was directed at the fins in the back to help circulate air across them.
Ours was the large 4 door fridge in our Forester.I have never seen a Dometic fridge without a thermistor. All of them have to have one of some kind. The newer ones just have settings on the upper board that change how the board on the back can "see" the thermistor.
These fridges use ammonia as a circulating through tuber and coil system to cool. This system is very susceptible to failure if they are not level. Over time the ammonia crystalizes and restricts or blocks the flow of the ammonia. When this happens the only choices are to repair the fridge (complete new cooling elements) or replace the fridge. I am not saying that is the case with yours but I did want you to be aware of the possibility. Speaking from experience lost my fridge this way. Replaced with Resi fridge.Fridge no working, but freezer is.
Your post brings up the leveling issue! However the thermistor, vent between compartments, and overloading, would be the likely causes in this instance.
