Is this a plug or valve or what?

Well I'm at the end of my rope trying to figure out this Dometic DM2652RBX refrigerator. I've established beyond a shadow of a doubt that the problem is not the control board (replaced a perfectly good unit), and it's not the heating element (same deal, the new one works perfectly), and it certainly does not have an ammonia leak. So the last possible explanation is a clogged ammonia system. I read through some old posts that recommended you can either turn the refrigerator upside down to "burp" the system or try "tapping" on the pipes. Well......I just beat the crap out of the pipes with a pair of pliers, turned on the gas, and put it to bed. I felt like that Russian on the movie Armageddon when he throws that lady aside and beats on the pipes of that space shuttle. Lol. It will either be at least partly cool in the morning, or I will drop almost $700 on a new cooling unit. Ugh!!! So here's my question. What is this right here? A plug from the factory after it was charged? It was covered with a little aluminum cover that easily slipped off and back on. There's a curved narrow "bottle-neck" just below the big horizontal canister. If I were an ammonia molecule trying to get stuck, that is where I'd stop. I especially gave that area a few good whacks with my pliers. I'm tired of screwing around with this refrigerator. No matter what I do, it only cools the back wall of the freezer just partially. Nothing else cools at all.

I am sorry to say your unit probably needs replacement. The sealed ammonia system is not serviceable without specialized equipment and knowledge.

How long have you left it on? It takes 6 to 12 to cool. The Freezer portion will start feeling cool first possibly within 30 minutes, but several hours the the whole unit.

What state do you live in. I have a deal for you. I have the Dometic that came in my first TT 2010 Passport after 2 years I thought was not cooling, but I wasn't giving it enough time. I bought and installed a new one and discovered immediately there was nothing wrong with the one I took out..

I am not even a novice, but are you trying gas or electric or both? Maybe the electric element is bad. Gas?

Sorry I re-read the post. Sorry

I usually leave it on for about a week before I give up and just turn it back off. Trust me, I've given it plenty of time with both the LP and AC settings.

I live in Kentucky. Thanks for the offer.

Worse comes to worse, do like we're doing. Chunk it and put a small residential in. Found a frost free one that fit the hole almost to the T, for $388. Right now we just run on shore power or genset, but will soon be doing the battery upgrade and inverter. Just a thought if it comes to replacing. There is just no comparing the Dometic, or Norcold to a residential.

Sorry to hear about the fridge, never fun….
I had a fridge go out, mine had an ammonia leak so it was easy to figure out. I did find multiple places on line that rebuilt them. I got mine for $300 and it went together fairly easy. The sites all had lots of info on them.
Good Luck
John

At this point, if anybody is willing to share some of the specialized knowledge and what equipment is required, I'd be willing to try it. I have nothing to lose.

Amen to that! I have since discovered that my particular fridge was contracted out by Dometic when they were building a new factory. I'm sure it went to the lowest bidder.
