Yellow powder is a failure of the cooling unit. Time to shut it down and not use it. You now only have 3 options.
1. Replace the cooling unit
2. Replace the complete unit
3. Replace the complete unit with a residential unit.

Yep, time to replace. A residential unit would mean electric only, right?

Correct.
As another poster mentioned the Novakool is a 12volt alternative to a residential.

If you like the benefits of an Absorption 3 way 12volt,120volt and propane.
Then best bet might be to have the cooling unit replaced on your existing refrigerator.
There area several options out there for these.

Unless you plan to do a lot of boondocking I would look seriously at going with a residential unit.

I replaced the cooling unit on our Norcold 1200 about 5 years ago. The first one went bad in 3 years. I again replaced it but have had problems since keeping it working right. Right now it's doing great, but if I had the whole thing to do over I would probably go with a residential.

DON'T use your fridge now! You could have a fire and destroy the RV!

Decisions, decisions. When folks talk about absorption fridge failures, 99% of the time they are referring to a Norcold.
These old Dometics, as far as I know, go on forever. They may not cool to the degree that a residential will but unless your plugged into shore power most of the time, a residential may not be your best option. IMHO.
Installing a residential unit is fairly involved in that many times the windshield has to be removed to get it in and the battery bank and Inverter/Converter have to be upgraded to accommodate the residential.
I've thought about this a few times trying to decide what I might do if my 16 year old Dometic gives up the ghost. At this point in time, I'd replace the coil.
If you are happy with the Dometics performance to date, why reinvent the wheel is how I look at it. But that's just me and I'm old....

Well.... after considering several options I have decided to go with a cooling unit replacement. The unit lasted 27 years and hopefully it will last that long again. We ordered from RV Fridge House in Arkansas. Not too far from us. Thanks everybody!

Good luck with your decision. My day is not too far away I fear.

I'm just trying to gain some understanding here for possible future plans if something went bad for us with our fridge. He means keeping his fridge but replacing the cooling unit means..."the guts"...right?

What's involved with replacing a cooling unit?

That is a great that it lasted that long. Let us know how the new cooling unit works.
