2017 Thor 37RB, front air conditioner won't turn on
I have a 2017 37rb that has two air conditioner units in the main area of the RV. These are controlled using the multiplex hard button / touchscreen unit. Both A/C units have worked fine for the past two weeks on shore power and now the front unit won't turn on. I checked the "front AC" breaker near the bed and all fuses and they're fine. I am currently running off 50a shore power. Both units worked this morning on shore power, then I moved to a new RV site. Mid way, I fired up the Onan generator and turned on both units, this shut down the Onan and flipped the 30a breaker that is on the gen. I've had issues with running both units off the gen and having it flip the on-gen 30a breaker. However never any issues on shore power. That said, now the front one won't work. Before when on gen power with the gen breaker tripped, you could still hear the clicks of the solenoids in the front A/C unit. Now it wont do anything, no clicks, no fan, no A/C. I have power everywhere else. Any ideas? For reference, its hot out. Was about 105f today and is currently 90f INSIDE the RV. Ugh!
