I could not see the exact source of the sound, but definitely coming from the refrige. My wife thought she could smell wiring, but I could not. We have turned the unit off, and would appreciate anyone's opinion on what could possibly cause the noise and apparent loss of fluid. The unit was running on AC, and had been working great. I did an online search of our model and discovered there was a recall for model and serial number that involved a fatigue crack in the boiler tube. Also, we are currently in Phoenix and would need to have it looked at, would appreciate any recommendations for service.
I just went through this with my Dometic RM2862 and I'm 99% sure yours is a bad cooling unit and needs to be replaced.
You can either keep the refrig and replace the cooling unit or replace the entire refrigerator. Replacing the cooling unit is a labor intensive job (3-4 hours), and may end up costing as much as a new refrig in the long run if you are paying somebody to do the work. If you do this, you're still stuck with a 10 year old refrigerator that may need service again at some point on the control board or somewhere else. If you replace just the cooling unit and have to replace it again under warranty, it generally doesn't cover the labor to remove and reinstall the replacement. This can amount to hundreds of dollars in additional labor costs.
If you replace the entire refrig with a new one, it will cost you about $500 more than a new cooling unit, but you have all new components all covered under warranty for two years. It only takes about an hour to install a new frig so your labor costs are reduced substantially too.
I think the only way replacing just the cooling unit would pay would be if you do the work yourself. I have done this before on a smaller refrig and it was a bit of work, and I did not have to remove the refrig like you would have to do on the larger refrigerators in an Airstream.
I contacted a local mobile RV service who is an authorized Dometic service person, and he was able to get a new replacement DM2862 from his distributor and just charge me the sale price that Camping World has them for right now plus freight. He will do the install in the trailer at my home for his $85/hour labor rate so I'm happy with this.
Good luck with whatever you decide to do!
