I was running the furnace to keep things around 55 degrees while working on a project. All was working fine. I left it on overnight and at some point ran out of propane. I came out to find the furnace fan running but no heat. I switched tanks and still no heat. Pulled the furnace cover and saw I was getting a flame sensor trouble code. I do have propane as the stove works fine. I could not hear the igniter clicking when I turn on the furnace. I pulled the igniter to find it was working, but I wonder if it is not getting enough juice. Would that be the igniter or the control board. Anything else I should check?
Thanks for any advice
