No,I unplugged it in the morning when I woke up...and removed it.

actually what happened was I woke up this morning and the thermomenter where the the pad is was reading127 degrees. The probe from the thermostat which was tapped to the pad fell of,cause I messed with the tape before I went to bed and guess it broke free...so I unplugged the UTH immediately .left the bulb on and removed the UTH..
