Hey Russel welcome back! To replace your Dometic Duo-Therm b57915.711c0, I recommend the Advent Air RV Air Conditioner System item # ADV39QR in white or item # ADV49QR in black.
There's no way to just replace your AC unit, you'll need to replace all your AC system components. This is due to the EPA changing the regulations on the refrigerant in the AC units at the beginning of 2025. They've been upgraded to R32 and your Dometic Brisk II has the now obsolete 410a refrigerant. None of the 410a components are compatible now with the newer systems. You will be able to use the existing wiring to power the AC system.
The Advent Air RV Air Conditioner System item # ADV39QR in white or item # ADV49QR in black are 15,500 btu systems that include an air distribution box that works in ductless orientations.
What kind of trailer or motorhome do you have?
