When I did open it, the lower element was on (240AC and making the noise they make) and would switch on/off with the upper thermostat.
I'm guessing a bad thermostat (electrical connections are good), any idea which one?
What if one thermostat is off a bit? Can I turn one a hair higher than the other and if it doesn't work put it back and turn the other one a bit higher? Does that make any sense?
Now that I think of it, if the upper thermostat turns on while I'm bumping it as I'm opening it up, that is probably the bad one....?
