I have an LG bator, just added a fan kit. It has been holding temps perfectly, the only problem is that I can only get it to go between 97.4 and 100.4... no matter how little I turn the dial up or down, it will not set to 99 or 99.5! I even used the knob trick! Any thoughts on this, and if I have to choose, would it be better to incubate at 97.4 or 100.4?? Ack! Thanks all - getting new eggs in two weeks, so have a little time to "fiddle" if needed, also DH has the ability to "tinker" with electronics if anyone thinks that could help. Thanks!
