Dometic 2804, cooling system clogged
I could use some advise on this one. My 1988 Excella 29' has a Dometic RM2804 fridge that has been working well until recently. Now, however, it doesn't cool on gas or electric, and just makes a constant gurgling sound. It seems like it's making heat on the back side, just not cooling at all in the fridge or freezer.
The local airstream dealer says the cooling system is clogged and needs to be replaced ($1500 parts and labor). Or, replace with a total new unit ($2300 parts and labor).
Is replacing the cooling unit something I could do myself? Special tools needed?
Would it be better to replace the entire unit with a modern one? And is that something I could do myself?
