I just got a 1588 Hovabator and the thermometer that came with it reads exactly 100. I put my reliable digital one in there and it won't go above 98.4, even when resting it atop the eggs. The 1588's red light is flashing, indicating correct temp of 100. Should I not change anything and let the 1588 do it's thing? I just set eggs 2 days ago.
