The breakers was also my first thought, but since you bypassed the AT switch and it worked, that’s probably not it. I’m assuming your Genny puts out 44amps and you’re not exceeding capacity? Mine will only run 2 of my 3 AC’s. If you’re comfortable digging into the ATS, you can cut off power and look at the Genny side solenoids to make sure the contacts are clean. Barring that, it’ll need replacement. I had to replace mine 2 yrs ago (rig was 6 yrs old) got the same one installed in my rig off Amazon. Pretty straightforward replacement.
