Also if you see condensation in the heater, then
it's time to change it. Moisture will cause
corrosions of the electrical contacts. and the
corrosion will cause them to stick.

I just pulled a heater out of my sump. It was 82.8 and it was still
heating.

How often do these go haywire? There seems to be lots of stories of run
away devices. You'd think they could design them to fail by turning off
rather then on.

I certainly like my digital thermometer w/ an alarm. I think it just
earned the $10 I spent on it.
