Just got back from a one-week trip back east. Everything was working fine until the very last morning when we had no heat and no hot water while overnight parking at a Walmart. The day before we had had plenty of heat and hot showers while Boondocking in a Cracker Barrel. The night before, while at the Walmart, we had hot water to wash our dishes. When we woke up the next morning we had no heat and no hot water. We had overnighted in Walmarts and Cracker Barrel‘s at least four nights on this trip. The rest of the trip we were on shore power, and every system worked fine. We can’t explain why we had hot water the night before and nothing the next morning. I haven’t checked the Alde fuses yet, and after reading here I am very suspicious of them. I will check the fuses tomorrow. One other thing that occurred, there is a symbol in the upper right hand corner of the Alde Control panel that had an icon of a thermometer in a bucket of water that kept flashing on and off. We could not find any reference to this icon in Alde manual. We appear to have plenty of propane, all the other 12 V lighting and systems along with the control panel seem to be working fine. Has anybody else had this experience. Thank you.
