2018 Greyhawk strange problem

[JFlightRisk]

I have been thinking that the control board (mother board ) could be the problem.The board you replaced did they Charge you $$ for it…

There were board issues a few years ago when they installed boards with the name Zhongding printed on a barcode sticker. The main thing to look for was a prominent bulge on the back side, and the gas side giving troubles. A long shot, but something else to check. Those boards were being replaced for free by Atwood.
