So I went to check on Will a few minutes ago, and the surface temperature in his tub was :cens0r::cens0r::cens0r: 135F. I immediately removed him from the tub and unplugged the flexwatt. Before you ask, I had it on a thermostat, which only read 94.1F. Thankfully, my snake hadn't been burned. So my question is: What the :cens0r: happened? The thermostat probe hadn't been moved, so why didn't it shut off? Is there anything I can put in place as a more reliable deadswitch?
