Atwood Hydro Flame 8520, replace or fix?
I have a 2011 RV with the Atwood heater. It won't continue to run and after opening up I find the burner is falling apart. I don't know if I have a problem with the board or any other parts also. When...

I have an 8531 in the 1991 Class C. (amazing you have an 8520 in your fairly new rig!) IMO get new!
The burner in ours was rusting out so lots of trouble with it. (The screen with the little holes in it was mostly gone so the flame was all over the place, confusing the igniter/temp set.)
No luck getting a burner at first and found out they are very different in different 85xx sizes so be careful there. I eventually found a used 8531 in a garage sale for low price, and swiped the burner out of that. The furnace still acts up a little. Sometimes the fan comes on and no heat, so have to go to the thermostat and switch off, wait, then switch on and now it ignites properly. Most of the time it works right though.
I was on the point of getting a new replacement. I recommend doing that for sure. Do note that the new ones are longer in the back where the ducts go, so you need room back there so it will fit.
