Thank you for trying. We called support services and come to find out, it was the fireplace. We had the fireplace switch in the on position. The fireplace and AC can’t run at the same time, so when the AC was kicking on, it would disconnect the FP power. What we heard was the fireplace power kicking back on indicated by a beep. Apparently, on our model, the FP switch is backwards, up is off, down is on. Hope this helps someone in the future. Big thanks to Grand Design service tech team for a quick and helpful response.
