Turn up the thermonstat just a little-wait an hour and then check the temperature. The thermometer being what it is I think going for a somewhat lower temperature might be good idea-100 degrees.
Repeat as necessary. When you put the eggs in, it may take a longer period for the temperature to go back to 100-DO NOT TURN THE THERMOSTAT UP. Humidity should be around 50%. I will be online in a few hours. Good luck.
