My 1992 Dometic RM2310 Fridge Stopped Working

Never heard of anyone pumping the coolant out of it and replacing it - sounds kind of sketchy. The problem is that sediment from the tubes corroding from the inside settles in the bottom and the coolant can no longer circulate. I can see how pumping out the old stuff, and maybe some sort of flush, could help but I've never heard it being done in the field so-to-speak. You can buy refurbished cooling units but I don't know what to what extent the old tubing is used. My 31-year-old Norcold has a refurbished cooling unit in it and it works great.

I would either look at replacing the fridge completely or replacing the cooling unit.
