I can't believe I didn't realize this. This just fixed my problem. Now I don't think anything is wrong, I just had the t-stat probe on an open part of the flexwatt, and it heated THAT part to 91, but the rest to 97. Can't believe I didn't realize this haha thanks a ton.
Yeahhh I forgot about quarantine. Looks like I'll have to keep the Dumeril's on its own heat pad for a while.
