Just bought a new 2023 GD 3740bh to live in full time with my son. Temps here in AZ have been 113-116 all week. I had both Coleman AC units set to “Lo Cool Auto”, I set the main thermostat to 83, and the bedroom thermostat to 78. I also installed a portable unit in the master that is set to 76 overnight and 80 during the day. I was advised to close the master bedroom dump vents and set that thermostat lower, since the portable AC is near it and it was not kicking on to help the main AC. I was also running a floor fan in the second bedroom to help circulate the air. When it is 113 outside it was staying around 88 inside the camper. After more than a month of running the two AC units, the fan, and the portable, I have recently come home to BOTH AC units shut off on their own (thermostat shows “off”). Not sure exactly when they turned off, but they came right back on when I reset the thermostat, and continued to run without issue until the second time (a few days later) I came home from running errands and they were “off” again. I checked the filters and they were clean. I make sure to reduce all other power suckers, as I know the units are working hard in this weather. We have put up shade screens on both sides of the camper, I installed heat blocking window film, and we are soon installing skylight and vent shade covers. My question is, why would the units shut off on their own? Is there a better way to set everything so it is cooler in the unit? Thanks in advance for your help!
