You really need a thermometer on the warm side and a theremostat. If you can't afford a thermostat at least get a rheostat. Heating pads get extreemly HOT and could burn your snake or worse. the warm side should be about 90 degrees. you should prob drop the Humidity about 10% it should be between 50-60% normally and you could raise it to 70% during a shed...

Hope you figure out the issue... Sorry I could be of no more help...
