Question:
Greetings Jerred H --- I'm tagging along to a note / question from "Leonard P" I want to replace a 13.5K BTU Dometic and bump up to a 15K BTU. (13.5 struggles a bit in Texas heat) My old Dometic unit has the following: Mfg# B57915.711CO Prod# 9360022005 Looks like the similar unit that Leonard mentions. The 6 pin connector is the same as in your photo. Difference is the control center has the following numbers - and connected to a dometic touch thermostat (horrible design PN# 3313191.000 Serial#724000273 Also on the tag is shows a number with no label - 3313377.000 Will the ACDOM150 work for my project? Thanks, Mike

Hey Mike! Thanks for all the information! The Advent Air Replacement RV Air Conditioner for Dometic Setup w/ Start Capacitor item # ACDOM150 is designed to plug straight into your Dometic air distribution box so you will still be able to use your existing thermostat.

Hey Mike, how did the upgrade to the 15K Advent Air unit go with your Dometic setup? It’d be great to hear if the plug-in connection and thermostat worked smoothly. Your update could make it easier for others looking to do the same swap.
