Once the probe gets to the set temp it turns off the heater until it cools to a certain temp. If the probe is not in the hot spot it won't get to temp and your heater will run on high.





so what i did was i taped the probe to the bottom of the UTH, is that bad or is that what i should do?
That will work.

Know that just because you set the tstat to a certain temp does not necessarily mean that is the number the hotspot in the cage will be. It can be higher or lower depending on a few factors. You need to test the hotspot and dial the tstat in so you get just the temp you want at the hotspot.

The substrate over the uth needs to be very thin, 1/4 inch at most.
