Question about Dometic Rooftop RV Air Conditioner
Model number: 57915.622The compressor kicks on and runs fine. All of the different fan speeds work fine. The new 5 button controller system works fine.The unit does not blow COLD air. When I took the shroud off, I felt both the evaporator coil inlet and outlet and the condensor. The evaporator was not COLD and the condensor was not HOT. I think this unit needs a 'recharge'. Where can I get this and how do I do that myself?
If the compressor kicks on and runs fine, this usually indicates that the freon in the system is good. Is there anything else that can obstruct the air into the unit or into the cabin? I believe that this refrigerant will be R-22, and may be difficult or impossible to purchase without a license. I also think R-22 is sold in cylinders larger than you'd want. Check in your unit, though. If, by some slim chance, it is R134a, you CAN buy and install this yourself, but, again, I doubt it is. Your best bet would be to have a local technician put the gauges on it and recharge it. Be sure to check for leaks. If you're losing refrigerant, you need to get the leak stopped, or you are going to just throw your money away.
Best regards, --W/D--

You need to verify what refrigerant the sytem is using, and if there are access ports on the unit to allow servicing, (many smaller units are not so equipped) If it is 134a you can puchase a kit at auto parts stores. (they usually have directions for use.. good luck :)
