[QUOTE=Adam;1349]Dear Gary D.,
I have never had to work on water heaters but they are pretty basic in design. Its possible to be one of the other thermostats.[/QUOTE]
I replaced the upper element with a 3800 watt and the lower with a 5500 watt as recomended by sears. Could that cause this problem?? The diagram shows a lower high limit thermostat but shows no part avail. the upper has been changed.
