You stated ....."have replaced gas valve and the thermostats with no difference"
Then you did not get t-stats tight against water heater tank wall.
I do not like Atwoods method of holding t-stats. Plastic washer pressing against a spring that has to be held compressed by three small tabs.
If tank wall is dirty where t-stats touch......t-stats won't sense temp (actually temp will go higher before t-stat opens
If t-stats are not tight.... same ----high temp before opening
If t-stats terminals/connectors not clean & tight....t-stats can open erratic
Turn water heater ON
When propane shuts off OR T&P Weeping hot water (it steams when it is released into atmosphere----doubt it is 210*F-----hot but not that high)
Collect a cup of full hot from faucet with thermometer in cup.......note highest temp reaches.
With that info...........easier to pin point issue
Post here or PM me with temps.
