semi-urgent -- heat/thermostat question

[A_Literal_Dog]

it's a jump start thermostat (two of them one for each)
sorry should've specified -- the hot side thermostat is set to around 105 in order for the hot side to be around 90. the cold side is set to around 90 in order for it to actually be around 80.

however yesterday the thermostats were set to those same temps but the actual temps were way too high

i am using two heat pads under the tub. the thermostat probes are in between the heat pads and the tub.

is it likely for both thermostats to fail at the same time though?
i am most definitely getting new ones tonight but idk i feel like something is off

If there was a power surge or something at your house, it's possible that they could both have been fried.

Is it reading 100/110° on the thermostat probe, or with your thermometer? What thermometer are you using to measure the temperature inside the enclosure?
