Question:
Will this part replace the advent ACTH12P control board? It looks just like the one in our AC unit. The Advent AC unit is installed in a 2015 Kodiak camper trailer. The actual board number inside the case that is like the one you show is ACTH12P. There are no part numbers on the Digital Control box that looks like the one you guys picture for this part.

This is a great question, Aslan, and thanks for the pictures.
Yes, the Replacement Digital Relay Box for Advent Air RV Air Distribution Boxes # PXXACRG12RB will work with your AC setup. I could see in your pictures that your unit is using the ACRG15 model, which this relay box is designed to work with.
Advent made things a little confusing since ACTH12 and ACTH12P are interchangeable. Usually, Advent would put ACTH12P on the circuit board and ACTH12 on the back of the thermostat shell. I included two pictures below showing the sticker on the back of the thermostat, along with the number stamped on the circuit board.
Hopefully this gets your Kodiak back to blowing cold air again in no time!
