I got this incubator yesterday. Its really old. And I am not sure how to work it. We added a computer fan on the inside, and can't get the temp below 100 when the fan is on...is the fan a problem? Or am I just using the temperature knob wrong? Any help is appreciated
You may want to replace the wafer thermostat if you haven't already. Wafer thermostats go bad. You can get a new thermostat online at Randall Burkey, or Strombergs for around $11. You can also replace it with an electronic thermostat.
As a note, I usually hatch at 100 degrees.
