Really? damn thats scary, thermostats should come with a backup probe or something, or maybe a wattage cut-off, example, normally my rack takes 163 watts to keep my temps, they should have a failsafe biult in the thermostat where I could set max wattage to 180 incase the probe ever slipped out, it would not go above 180- watts. Man if I had money to design my own stuff Id be a millionaire
