A/C cycling with error on thermostat
I am sure this is a common issue but I cannot find anything by searching. About a month ago we went camping for a week in Minnesota and used the AC several times. No issues. When we got back to Illinois I plugged the camper into the house circuit (20 amp, 120volt) and the A/C would cycle on (10 sec) and off (10 sec) and flash an E1 error on the Dometic digital thermostat. I read here that I had to totally cycle the power, including the batteries and that seemed to work. It ran like a champ. Fast forward to last week. Set the wife and some of her friends up at a campsite but the AC was acting up again. I tried resetting it again but to no avail. I worked on it for about an hour, no luck. The strange thing here is that we noticed the GFI in the bathroom was tripped. I reset it and it did it again later. During the three days she was there she did get it working for a while. It was July! Not happy campers! (Just for reference I set them up on a Tuesday and left them there and picked them back up on Thursday). We are camping in a couple of weeks and I would like to avoid a repeat. Had the RV dealer look at it and he found nothing wrong. Everything worked like it was supposed to. AC cold and no GFI. I suspect that bad power was the problem in the campground (not sure about home). If that is the case is there anything I can do about it? We regularly camp at that campground and have never had an issue. How can I prevent the issue or at least know prior to setting up?
