In this guide, I show you how I replace a Dometic Brisk 2 (B57915.XX1C0) with a Dometic FreshJet 3 (FJX3473MWHAS).

The original Brisk 2 has its control box integrated into the rooftop AC unit. The FreshJet 3 replacement is designed for mechanical controls, so it requires a separate control box.

We’ll install the Dometic 3316230.714 control box kit to make the new FreshJet 3 compatible with the existing system.

Follow along as I walk through the replacement and get this RV’s air conditioning system back up and running.

Get back to camping!
