Norcold fridge not cooling

[Pexring]

Recently bought a 1991 Holiday Rambler. It has a Norcold fridge that's probably about 10 years old. The fridge isn't cooling so well. I do not know how much the unit was used before I bought it. It could have sat awhile. Both the propane burner and electric heat rod work well. Would taking the fridge out and tipping it upside down to stir the ammonia do the trick? Down to my last options. . . .

Check for stored codes
Clean the burner tube and remove all debris
Check the resistance of both heaters. If one goes out the symptom is poor cooling.
Make sure it was installed properly, installation manuals are in the files section on this site.
Check the door seals
Move the thermistor UP on the fin if you have one that moves
If all that fails search for the 'Muddypaws Mod' on this site.

Mine stays right at 33-34F in the refer and -18 in the freezers on setting 2 or 3 unless the DW leaves the door open or takes something directly out of the oven and puts it in the refer. Yeah, she's done both......

Took the fridge out to try tipping. As soon as we tipped it ammonia started pouring out of it. Broken tube. Now shopping for a new Dometic fridge.

If the "box" is still good, it's usually a lot cheaper to replace the cooling unit on the back rather than buying a whole new refrigerator.

What are the dimensions of it? Myself as well as a few others on this forum have good working Norcolds in the classified section.

What model is this broken Norcold fridge?
