Hey Tim, the Dometic RV AC Unit part # DMC53ZR that you referenced can be used in your ducted application but you will need a new air box too with the part # DMC43ZR since this will not work with the air box you have now.

Thankfully your RV roof is white and not black otherwise that might be hot on your feet!

I am confused. What is an air box. The unit just sits on the 14.5 x 14.5 hole once I remove the damaged one.

@TimD Was there a low portion of the assembly that was on the inside of the RV that had a vent system and controls you'd normally access from inside the RV?

@JamesonC I installed the AC exactly as the other. However, compressor works but no air. I am wondering if there’s a switch I need to do to tell it, theirs no air box and that it’s ducted. I would expect at very least fan would work

@JamesonC Unfortunately a manual was not enclosed in the box with the Dometic AC so I don’t know what the dip switches are for a ducted AC running on 20 amp. But I can tell you the wiring is correct. The control board on the old unit is nothing like the control board on new unit.

Hey Hawk, so the Penguin II like the part #DMC86ZR that you referenced can attach to the air box you have now from your Penguin I but the thermostats are not the same so what you would need to do is upgrade the control module with the part #DMC25RR…

Hey Andrew! Yes, Furrion does have a Chill Cube model with a heat pump. This was actually just released for aftermarket sale. You will need a complete system to make the switch, new R32 units aren't backwards compatible with old R410A systems.…

Hey Melanie. The reason you can't find a replacement for your GE ARC15AACBL2 15,000 btu air conditioner is because they phased them out. In 2025 all RV AC systems had to change over to a new coolant called R32. This was a EPA mandated decision.…

Answer 5

Hey Tim welcome back! Your ARH15AACBL2 GE AC unit has the old 410a refrigerant in it so the GE Appliances item #GE64FR you were looking at isn't going to work as a replacement. The EPA mandated R32 refrigerant has been used in all new AC's…

THey Brian, the Coleman Mach Signature Mach 15 part #CM32RR is a really solid AC unit. As far as how it compares to the Furrion Chill Cube #FR69TD it only has the advantage of working more consistently with furnace controls. Aside from that the Chill…
