There replacement rooftop AC units available for your Dometic 57915.621 system, but you'll first want to verify what style connector your current unit has. To find this connector you'll remove the cover to the air distribution box to gain access to the controller and then look for the wire harness that hangs down from the rooftop unit and plugs into the controller. It will have either a 6-pin or 9-pin connector on it. If you have a 6-pin connector you'll want the Furrion Chill HE Replacement RV Air Conditioner Unit # FR26PR.
If you have a 9-pin connector then you'll need the Furrion Chill HE Replacement RV Air Conditioner # FR82PV since it comes with a wire harness adapter. Swapping out the units is as simple as remove the four bolts that clamp it to the roof of the trailer and the single wire harness plug in so it shouldn't take you too long to complete. Just make sure you have an extra set of hands to help you move the units around.

Kevin, I have a 57915.621 duotherm with 6 wire plug and 4 wires coming from the thermostat. Per your instructions the 6 wire plug goes with the fr26pr, is the thermostat wiring going to be the same? Currently from thermostat to unit wires it is,red to red, white to yellow, green to orange, and blue to blue. (I have pics if needed)
