Well, it is looking like a bad TC PCB. I'd forgotten that I had a thermocouple reader for my multimeter so I hooked it up and the TC worked perfectly. I reflowed all the solder joints on the PCB with my soldering iron and it still reads a constant 93 degrees. The LED lights up just find so I'm guessing the problem lies in the amplifier chip.
I'll be contacting UM Support about a replacement this week. Thanks for the help!
Sounds like a bad TC board. You can visually check if there is a soldering error, also check if the blue light goes on, and you can contact UM support for a replacement.
