Atwood gas water heater

[bnecaise74]

I have a 2017 prime time avenger ati. The gas water heater has a hard time lighting. It will ignite about 5 times before it will finally light and start burning. It's also starting to smut up the side of the trailer. What are some things I can check to get this thing operating correctly. Thanks!

I had the exact same issue. It was a spider web blocking the air Venturi. Use an air compressor or brush to clear them

Check for spiders or mud dubbers in the flu. If you need to clan the small gas orifice do not stick anything is the hole ( use air or soft brush) The smallest change in the size of the orifice will cause the WH to malfunction.

X2. Had same issue on a previous rv and found spider web. This keeps the air/gas mixture from being proper ratio. If you have a outside burner and it burns yellow, this will blacken pots, it's same thing.
