My Norcold single wide looks to have that yellow residue on the tubing from top to bottom.

Am I on borrowed time with this unit?
Well beyond borrowed time - it is dead.

Is your product only for Norcold? Can it be used with Dometic?
Not my product, but it works with any brand and model of absorption fridge. It was invented by Paul Unmac, a practicing engineer and active Rver. See their new website:
ARP DEVICE

I did a forum (not Google) search and came up with several discussions about the Samsung fridge. Here is the latest one.

This one won't work, as I have the single wide Norcold that is about 24" in width.

The only unit that I can see to work is the Whirlpool.

Ahh...my mistake, I apologize. You've got one up on me, I didn't realize there was a residential option for single door refers. Best of luck with your project!

There are some other options.
Frigidaire
Summit
Danby
Haier
Use Lowes and Home Depot to do a search for the size, color and features you want.
I have settled on a Frigidaire model FFHT10F2LB
Make sure you read the install requirements on the unit you choose for your install. Some require a lot of side and top clearance. Others require clearance for the door to open. Whirlpool is one that requires clearance on side wall for door to open.

Well, I'm not so sure this is amonia leakage or just plain rust.

Here are some decent pictures. What do you all think...

Definitely rust. Looks like mine and mine runs fine.

I don't see any yellow powder in those photos - just plain old surface rust. That can be a problem eventually if left untreated, but ammonia coolant leaks generally come from pits that start on the inside, after the sodium chromium deteriorates and the ammonia starts eating at the tubing.

Very good to hear this!!

Now, to address the second problem...

When selecting A/C only on the unit, it trips the GFCI in the bathroom. Reset, same thing over and over.

Hooked up a vaccum cleaner to the power outlet for the Norcold and the breaker never tripped no matter how many times I turned it on/off.

Any ideas?

A GFCI fault from the fridge is usually a flaw in the electric heating element. It could be some corrosion around the wires to the heater, allowing a bit of the current to leak to ground instead returning via the neutral, or it could be the heater element itself.

Unhappy Works but (and a BIG but)

Just a report on my experience as a warning. Yes it seems to work (at least I haven't had a fire yet). BUT my experience this past summer says beware. This product and its developer/inventor have a very long way to go to make it a user/installer friendly product. Anyone attempting to install should unless very lucky (or already refrig industry savy) expect a long aggrevating learning curve and some of the most convoluted support material I have in 30 years of technical experience ever seen. And watch out for buying from anyone other than the inventor at arp.com.

Heres my experience: My Norcold temp controller went out from a lightning power surge. Getting a tech to com out to deal with it ended up impossible and extremely expensive and no one would touch the arp. After research I found the product via a blog on "the Norcold Guy's" web site. I talked to him and ordered it after being told it was a great product and easy to install. They sent a controller for the wrong refrig and didnt even know there were different models for different refrigs. Then it was sent to the wrong address and instead of overnite it went out 4 days later. After finally getting it, it didnt work (remember wrong refrig). Went to the Arp web site and tried to plow thru the product manuals (the worst technical writing imaginable). Had to talk to the owner. Was told I had the wrong product and had to reorder. Did so. Called owner back to get much needed clarity on bad product manual. Owner confuses me with some one else and sends me on a wild goose chase. Finally get it running only by trial and error and numerous redos.

In short It took 5 weeks to get it running correctly and a lot of spoiled food and ice cubes. But it does finally seem to be doing the job.

Yellow residue IS dried out sodium chromate (anti-rust inhibitor) that has leaked out when tube cracks from overheating. Overheating causes metal fatigue due to lack of sufficient coolant flow.
Metal is stressed/overheated until it cracks

Sodium chromate doesn't 'deteriorate' ------it crystallizes from overheating.
Crystals plate out on inside of tubing causing obstructions to coolant flow which means even more overheating ......problem is accumulative and permanent. At least until cooling unit dies/leaks

Other source of leaks....cracks in tubing at welds where electric element holder is attached. Thin walled tubing/over penetration of weld...metal fatigue------LEAK

Yeap, agree with all those things, but there still isn't any yellow powder in those photos.
