I am having a bear of an issue, and was wondering if you could help. I have always used my Helix proportional t-stat with FWatt; all the way from my 9tub rack, to my now one-tub setup.

It has stopped working. I came home last week to a cold FW. the probe was in place right between the tub and FW, as normal. The thermostat had the right degree on it. And there was a faint buzzing sound emitting from the whole thing. I immediately unplugged it.. I am actually scared to plug it in, and am using a backup UTH/rheo; not ideal.

What on earth??! I did notice a small area of the cord (that goes into the wall) is exposed. My mom's cat might have chewed it; maybe the bed rolled over it when I moved things. Not sure; do you have any idea what is going on?

There's just the one piece of Flexwatt now, since I only have one tub/snake. It is on a metal "utility" shelf; could this matter? Luckily the room was pretty warm that day (around 75 degrees) and my snake has no ill effects.
