[Shop-talk] Really hot water

[David Scheidt]

We've suddenly got really hot water (170F!) coming out of faucets.
The water heater is a pretty standard double element electric job.  I
opened the covers, and the settings were where I'd expect them to be
(right in the middle.)  The upper element is hot to the touch.  I've
cranked its setting down, and I'll see if that makes a difference once
we've used up some hot water.  Do the elements ever stick on, or is it
likely to be that the thermostat has died?  (and is there a way to
test it?)
