I know this seems like a stupid question and it could be me just being impatient but here it goes. A couple of days ago my temperature went up to 80 degrees and it's stayed there ever since. At first i turned my thermometer way down to about 70 to try to get it to decrease and yesterday morning I completely unplugged it but still there has been no change. Now I know that it takes a lot longer for the temperature to go down then it does to go up but it hasn't changed at all. Should I try getting a new thermometer or just wait and see what happens? I want to get my temperature somewhere around 75.
