I ordered a new hova bator and it came in yesterday. It's the model with the fan. I'm having probs with my temp. I had to set it up wrong. I set it up last night and this morning it was 115. And I turned it down all the way I could before I left for work this morning. I threaded the screw thru the hole and screwed the wafer on. But I just don't know if I did everything right. What could I have done wrong?
