We have a 09 3500RL and I was testing the furance today and it will run fine for a while and the sounds like a motor with a miss. It does this for a few seconds and returns to runing sooth. It is not the fan motor but the burner. You can stand by the exhaust and hear it or from in the coach. Both tanks are full. This is the first time the unit has really be run. It was in the 90's when we picked the unit up. Any ideas? Thanks Bill

Take it to your dealer to look at. It could be lack of airflow causing it to overheat and shut down temporarily. A gas pressure problem, Spider built a web or many other things. Warranty is a good thing for those problems. Put it on the list.

Have the dealer check the propane pressure at the heater
