Girard tankless water heater no power
I have had this water heater working on my last trip last year. It's been at the dealer for 4 months for a different issue. When I finally got it back last month we decided to take it on a short weekend trip not far from the house to test to see if they actually fixed the issue (heater ducts). Went to turn on the water heater and I am getting no power to the panel inside the bathroom. I have propane and power but not to the panel. Checked the fuse box, and that is not blown. Other than checking the actual fuse on the tank, does anyone have any other ideas??
