This is our first family camping trip with the baby and my third camping trip in the camper total the heater work just fine the first two camping trips that I went on and this evening we tried to run the heater and nothing works. This which seems to be in good operating form and the fuses not blown, the propane is on and everything else in the camper is working perfectly include in my fridge. Has anyone had this happen to them before and if so if some other things I can troubleshoot other than that the fuse the switch and the wiring that I cannot really trace and the propane thanks for the help
