I don't know maybe you did mess it up but I have parked several times unleveled and not had any issue. It's odd that it just stopped working. If the LP is lighting it is beyond me. Obviously you have a issue that a fan is not going to fix. I'm thinking it shop time. Or maybe a good time to switch to a residential? I have heard great reviews about the Amish fix. Someone here just did that and it works great. There is a Amish guy in Shipshewana that converts you've fridge. Not sure if you are close but that's a real good option.
On edit I see you are in Washington State. Not very close. It would be a very nice road trip. Lol. Good luck. Let us know the fix please.
