I have a new board and have installed it to replace a board that keeps blowing the 3Amp Fuse (F1). The problem is, that this board is blowing fuses too. I know it's wired right, it works fine when in emergency mode for heat, which, runs propane, but if I switch it to use the heat pump for cooling or heating it blows the fuse. Makes me think it's a problem in the heat pump. Any advice on what to look for now?
