My Atwood GC10A-4E water heater only heats to just slightly warm. It does the same thing on gas or electric. 2005 Fleetwood Southwind 37C with only 20k miles. My first thought was the circuit board, but when I found the cost to be about $200 for the board, I thought I might check and see if anyone has any other advice or recommendations.
Check to make sure the outside shower handle control is off. If it is open but still shut off it will mix the water with the cold side and dilute the hot water, at least on my trailer it does.
