I unplugged from the house, started up the generator, and watched the PI display as I tried to turn on the AC. The lowest it got was 117. I turned off the genie bypassed the PI surge suppressor and had the same results. Looking more carefully as the thermostat screen flickers, I believe the code is E1 - then the E goes away and something else flashes, then it comes back.
I'm really concerned now because not even the fan will come on when I'm plugged into the house power - and I have a trip planned this weekend. I've never had issues before and don't understand why just trying to run the AC from the genie would cause this.
J Free - I took the cover off, but do not see any fuses inside the generator. I attached a pic. Hoping the sketchy manual I got talks about this.
