Re: Should I repair the Fridge
I'm not sure what specifically you mean by your fridge just stopped cooling (meaning it won't turn on; it turns on but the compressor doesn't run; the compressor runs but doesn't cool; etc.?) but here's what happened to me a few weeks ago and how I fixed it, if it helps:
I turned the fridge (Norcold DC0051) off at the dial after our last trip in January. I turned it on two weeks before our next trip in April. It turned on and the compressor would run but wouldn't cool at all. I tried kick starting it by stuffing it with frozen items. It kinda seemed like it worked but was really just the illusion of those items cooling the fridge down. I noticed the compressor would not turn off, no matter how low the dial thermostat went, and ran continuously. I checked all electrical connections and voltages. I followed Norcold's electrical troubleshooting guide to a T (it is listed somewhere on the forum here) and everything seemed to work. A couple days before our trip I did a final troubleshoot before giving in and getting an ARB fridge: I found a couple posts recommending "burping" the fridge (turn it upside down for a few minutes) and found one post somewhere about using an orbital sander (without the sanding pad) against the cooling coils in the back. I did both and it started cooling immediately and the ice box iced up within minutes. It even seemed to cool better than it had before.
Personally, I attribute it to the orbital sander loosening whatever sediment may have occurred in the cooling lines (the post I had read mentioned something about the cooling tubes being laminated on the inside, but I don't know enough about how they're made beyond an "it's plausible"). In any case, I'm not overly happy with the fridge but I'm happy I still get to decide when to replace it rather than it making the decision.
