Emptywagon2, my thermostat crashed not long after the eggs were set, and I don't know how long as this was when I woke up and found it. I had another coolerbator running in the basement as an experiment, and swapped out the thermostats and everything has been good since. Not sure how long it would take to swap out the stat on your's, mine only took a few minutes.
I think that is my problem... I moved the eggs to the LG & praying that they make it.
Have you double checked that your thermometer is accurate? I'd double check that too.
I don't think it was the thermometer... I had two different kind & they both read the same. Ugh! I should have known something was going to happen...things were too perfect!
