Electrical problem
Grand Design Imagine 2970 TT 2017 My rig is at a full hookup 50a site. Several days ago the electrical appliances would shut off and immediately come back on. The air conditioner fan simultaneous...

I agree the issue may be on the 120 volt Shore power side of thigns as shore power feeds the conveter. which convets shore power to "Battery" power if the converter is not eating 120vac then it's not working (Technically that is a converter problem but... Well I think you see why it's not) This makes the lights dim and all but A/C fans run slower.
Now the A/C fans and compressor are 120 volt devices but they may rely on 12 volt Relays to activate .
Some differences between a trailer and motor home so I'll do it this way (motor home parts) note a trailer WITH a built in generator qualifies as "motor home" here
One more (optional) part
Suspect list
Shore power
Shore power outelt (park's problem so far)
Shore cord plug
Shore cord outlet (Optional if detachable) and the RV's inlet (LIkewise)
(automatic transfer switch) (Built in generator only)
Main breakers in main breaker panel
Branch breakers
Bus bars
Check to insure breakers are fully seated (they have not tipped foreward and out
And using a flashlight with shore cord UNPLUGED (If possible where you can see it) Check ALL screws and conections
Many RVers I have found seem to have a few screws loose.. One of mine took a #2 square bit and 3 1/2 full turns of the driver before I was happy.
While poking around look for any discolored wires (indicating overheat) sure sign of a bad connection.
I will say again when working in the breaker box UNPLUG and if possible secure the plug where you can see it.
There are also screws that can come lose in the Auto Transfer Switch
Problems I have seen or personally had
Bad park breaker
Bad park outlet
Bad plug connection (mine)
Detachable cord outlet end screws not tight) A brand new 5er and I can tell you he was ..... well you can imagine what he was)
loose screw on inlet (mine again)
loose screws in the breaker box all over the place
Bad connection on an internal plug/socket (mine added you likely do not have an installed hughes Autoformer)
And on the 12 volt side of life.. in addition to dirty battery terminals and assorted other bad connections A BAD WIRE. yup. the wire was bad. (I had and I saw two others)
