The yellowed plastic is a sign the ammonia leak was inside the box.

... This past summer our 12 year old Notcold quit & we faced your same dilemma, and since we like Boondocking & State / Federal Campgrounds we needed a 2 way replacement.... Went with the newer (& larger) Notcold.... Ease of installation without modifications....NOT inexpensive and only went from 9.5 to 10 cubic feet on our model.... Don’t have to worry about door seals leaking on fixing the old one ( or something else failing)...

That extra space is very attractive. Dometic claims to have gained it by using an improved insulation material. Supposedly it is the replacement for the RM2652 but I can help but think of the old saying about "stuffing 10 pounds of s**t in a 5 pound bag". It usually doesn't turn out well. I'm hoping someone on the board has done this switch and they will know more about the details like whether the gas inlet remains in the same location/orientation so the gas line doesn't need alteration. I have not been able to find reference to the fact that the same Ammonia based refrigerant is used or not.


Ammonia based coolant has not changed in 50 years. You might be confusing with the Atwood refers that used Helium. Doug

Those Atwood units still use ammonia as the main coolant (and water to absorb the ammonia); the helium only replaces the hydrogen gas used in traditional absorption fridges. (The purpose of the gas is just to take up space and provide pressure in the right areas so that the ammonia evaporates and condenses as desired; any gas that is nonreactive with and practically insoluble in the water and ammonia would work equally as well.)

3762 a tad wider--problem or not? Have to remove any outside trim and measure the actual access.

In 2015 I bought a new Dometic 2652 to replace the old failed unit, a 1999 Dometic 2652 with the dreaded ammonia leak. The interior was similar but the plastic adjustable shelving was thinner and a little cheaper quality IMO. Save the older shelves/drawers if you can because they are interchangeable. What made a huge difference for me was getting rid of those older idiotic finger pull door handles and replacing them with newer hand pull/thumb latch handles. They are much easier to open/close.

Other than that, the unit was very similar. The "reduce exterior moisture" switch/function was eliminated. If I remember correctly, it was about $1,300 installed, including tax, in Yuma, AZ.

The freezer runs at 0F and the refrigerator stays at 34F year round, just like it should. No issues so far.

AH-HA....I wish I could have bent your ear about 40 man hours ago. One peek inside and you would have sent me to the store for a new one. Thanks for that Chris, it makes me feel like I did the right thing by buying a new one.

I sure am good at putting it in and taking it out now and know what to check if it acts up. I just got back from town with a new one. I will unload it in the morning. What gripes me is I think I will have to remove the door frame to get the old one out and the new one in. I'm going to do a little more measuring in the morning.
