Hot water heater too hot

I was getting too much hot water in comparison to last season. I’ve changed the thermostats, and made sure the air pocket was replaced. Still heating too hot. I used to shower with only the hot water on.. now I have the cold water on full at the same time.. Could things still work to this level but still have a bad circuit board? The two lights on it arent lighting while in demand..

Atwood 6 gal heater, both electric and gas run without shutting off.. I havent let it go to the point that it will blow the pressure relief valve, but the water is too hot to touch, and steaming...

What brand of water heater? Suburban offers two different temp switches.
