Replacing A Dometic Duo-Therm 57915.541 With An Advent Air Low Profile Condenser Unit

Published 05/06/2024

Question:

Looking for a replacement for a Dometic Duo-Therm model 57915.541, cooling only no heat pump, with analog thermostat. Does the Advent AC come with a control box, or do we swap out the Dometic control box from the original unit? Also, can we use the existing Dometic analog thermostat?

Hi Ken,

The Advent Air Low Profile RV Air Conditioner for Dometic Setup # ASA99YR only replaces the rooftop condenser unit and would plug into the Dometic controller. Since you don't have a heat pump you'll likely have a 6-pin wire harness connector, but I'd still pull the air distribution box cover and confirm that you do. If you find you have a 9-pin connector instead then you'll just need to pick up an adapter # ACCOLKIT.

With this style of replacement your current air distribution box, controller, and wall thermostat would all still be used.

Do you have installation manuals for the ASA99YR and ASA38YR? I have 2 customers, one with Dometic Brisk II 13.5k and one with a Carrier 15k, that will need replacement soon.

@KenS The manufacturer, ASA Electronics, unfortunately doesn't have a manual online for the low profile # ASA38YR and # ASA99YR so we don't currently have one tied to the part, but we do have an installation video where John will walk you through the process. When you purchase the unit there should be a paper copy of the manual included in the box.
