I think I would call someone else out. The unit could be dead. But there is no reason it can't run fine if the unit is cleaned up and out correctly, vacuumed with a filter dryer installed. How is Ducane going to find out what happened unless he tells them? It is probably out of warranty anyways, so who cares? Last time I checked, Ducane doesn't drive around looking for units and checking on their history. I would never hang one of my customers out, I try to help them as much as possible. It pays off in the long run. Insurance might pay for it, but you'll end up paying for it in the long run in the form of higher premiums or getting dropped, depending on your insurance co.
