Another Dometic AC Question

[Partsbob]

My 2020 Dometic BriskAir II 15k unit will sometimes only run the fan without the compressor coming on, though it seems only during the night, with the fan set to Auto. I’ve confirmed the thermostat is accurate and usually set to 74 degrees, and will operate normally when it calls for cooling, but will come on with fan only for a few minutes in early morning while connected to shore power or generator. Last night it happened at least 3 times with the outside temp also being in the 70’s. Is anyone else noticing this happening too and considered “normal”?
BTW, this is our 2nd unit after the original (2019) lost all refrigerant and the new unit came with the fan blades being very out-of-balance, causing a lot of vibration in the TT for about 6 months before replacements finally arrived! The new unit was so loud it would wake my wife & I every time it came on and I couldn’t tell if the compressor was engaging when it came on, at least not until I felt cooling. I have installed a Dometic-approved soft-start capacitor to allow us to use a 3800w Inverter Generator when boondocking and sure that has nothing to do with this “issue” in question.

I recommend runnng the fan on HIGH, not auto.. Two or three reasons
ASeems to reduce icing of the condenser (If that's a problem)
Equalizes temps through the RV
Drowns out noise. both the compressor and "outside" (Neighbors having a knock down/drag out) your mind swiftly "Filters" the fan noise if it's always on. Not so if it's on Auto.
