ASA provided me instructions on how to verify if the end of line (EOL) resistor is present in the gateway. My issue is I cannot find the gateway to verify. I removed the air return vents (#1 and 2 A/C) inside the coach as the instructions show, but all I see is the ducting. Do I have to go on top of the unit to access the gateway on this model RV? Any help is appreciated.

Yes.. I am fairly well versed on Alpines.. I own one.. The GATEWAYS for your roof A/C units are laying inside the Evap coil Cover on each roof A/C unit. To get access you have to First remove the plastic outside cover..
I am Guessing your 2019 has the Dometic NXT series roof A/C units.. toward the front of each unit you will have another cover to remove.. Once you remove that cover look down where the EVAP coil is into the duct and you will see the black plastic box ( gateway ) with wires attached..
I gather your issue is with the FURANCE and it wont RUN? if it wont come on at all you need to check the two BLUE signal wires on the Zone ( Usually Zone 1) on the control board and gateway to make sure they are making good connection otherwise furnace will never turn on
** Nothing that you need to access for your issues is from within the inside for the Control boxes and gateways for each roof A/C unit
