Oh no that's terrible! I almost had a catastrophe like that happen to me! Luckily a WEEK before a friend of mine told me to buy a dimmer just in case something weird happened with my thermostat. A week later I checked on the snakes and my thermostat was melted! The dimmer must have overloaded and shut everything off. I was so lucky! I've still got that $10 piece of equipment safe guarding my snakes!
