Replacement AC Unit for Dometic Duo Therm that Uses Same Controls
Question:
I own a 2003 National RV Islander. I need to replace one of the Dometic A/C units. Duo Therm Model 630515.321 serial # 24930007. What is the model for an exact replacement. And is it available. I’d like to be able to use the original thermostat setup. I understand I should be able to swap computer boards and have no problems.

For replacing the Dometic Duo Therm that you have now you would want the Advent Air part # ACDOM135B which is also a 13.5k BTU unit. Since what you have now has a heat pump you'd also want the heat strip part # ACMHD and you'd be set. This will allow you to use your current wiring and controls as well.
