Norcold. LP side. Vid enclosed.

Thanks for looking. We recently purchased a 2000 Itasca 35u (sorry, I said 36u in the vid) Suncruiser and continue to find things we need to learn!!! Up until a week or so ago we had never run the Norcold on LP.... Well, I should't say that. I did run it on LP once overnight to get the fridge cool but soon found out after we set foot down the road that we had a major LP smell inside the coach which set the LP detector off. I just assumed the wind of the road blew the flame out and it never re-lit so we shut the fridge down and didn't run it again until we were at our site and had AC power. Fast forward to two weeks ago and we ended up at a site that didn't have AC power when we arrived so I started the fridge up on propane. About 10 minutes into running the fridge we could smell a distinct gas smell. It wasn't raw propane but more so of a combusted smell. Again the LP detector did it's job and went off so we shut the fridge down. This past week I've done some research and have done many of the tests for LP leakage. I did the soapy water test and found nothing. I pulled the inspection cover off the burner and found a very large pile of rust and debris. After cleaning that up and blowing compressed air through the burner the fridge now sounds like a blow torch when powered on LP! I'm assuming this is ok but just want to make sure before leaving it run for extended time. Video is attached
