You're doing a good job checking all of this before you put the snake in, btw.
I agree!
I just moved my guy into a 40 long aquarium that is on a stand that's open underneath. The heat pad is now open to air, but the temp reads 90, even with the rheostat turned all the way down. I added about 4 inches of aspen on his warm side so he can get as close or as far away as he needs to. Just thought I'd toss this out in case you were having a heat issue with your heater getting too warm.
yeah, its one of the junky kinds! lol, i got it in a pack of a whole bunch of stuff! I will try to get another one soon
If it feels warm to you then it's too hot for the snake.
If you don't want to buy a thermostat ($22 and up), you can use a $9 lamp dimmer from WalMart or a hardware store. Make sure you also have a digital thermometer with a wired probe ($9-$12 also at Walmart hardware dept) and put the probe right on the glass over the UTH, under the substrate. You want the temp there to be about 85-86. You can adjust it with the lamp dimmer.
If you use a ZooMed UTH with nothing to control it, it will quickly heat up to 120 degrees or higher which is dangerous for a corn snake. You really can't rely on turning it off manually. It will get too hot long before that.
The lamp dimmer and thermometer with probe in no way would have contributed to a fire.
Not to dissuade anyone, but this isn't an absolute statement. Many dimmers do generate heat as a result of their reducing output power. Under normal operating conditions this setup should be A-OK, but as with all electronics if one were defective or badly wired then yes, a fire could be a very possible outcome.The lamp dimmer and thermometer with probe in no way would have contributed to a fire.

Also, the commonly used heating element Flex Watt isn't approved in some countries because of the fire risk.
