For the last few days I've had it hooked up to that, keeping my temps at the ideal amounts for the duration until today. Now it is a boiling 100F+ at the lowest setting. It was 109F at medium when I first noticed the issue.

I am thinking that it's just a malfunction since it was working fine for days. It's a Reptitherm heater if that matters. I'm just going to take it back to the Petco and order a new one off of Reptile Supply Company because I have had great experiences with them.
