Thermostat failed??

[Hugsplox]

A little update ..
I ordered a new thermostat which is arriving today . I tried to stay awake as much as I could to be aware of the temps . I went to sleep 2am as my bf is waking up at 3am so I hoped within two hours nothing will happen as the whole day everything was working perfect
He wakes me up though because the warm side was 100F! I saw though that the thermostat probe was moved, I usually place it under the CHE hanging on the guard , now it was on the hide almost behind it. The snake was chilling under the CHE and acting normal , it was also the first time I saw him on the warm side actually . The cold side at that moment was 77. So now I am more confused . Does it mean that the corner of the viv at the warm side is so cool that the thermostat did not switch off at all ? Was the snake enjoying it ? I guess if he did not like he would stay at the cool side . Also , may it be that the thermometer is wrong as well? ( I am waiting for the gun to arrive, too) and last do I place the probe correct and how could I fix it in place better so it won’t move ?
thanks for all the help I am getting here !!!! Taking answers from people makes me less stressed as nobody from the people I knows owns a BP so I can’t get any advice or experience story from someone ..

All of my thermostat probes are held in place by aquarium grade silicone. If you have probes inside the enclosure where your snake can get to them and they're not secured somehow, odds are they'll get moved. Probe placement obviously has a lot to do with how well our thermostats work, so if that probe gets bumped 6 inches to the left, your thermostat is going to think you need more heat, and then you run into the issue you're having.

Essentially you need to find a way to secure your probe or your snake will move it and regardless of what thermostat you use you'll get whacky readings. DO NOT put tape or anything that might stick to your snake inside your enclosure. Again, personally I like aquarium silicone and I've been in that hobby so long I always have plenty on hand. It's inexpensive and easy to use.
