I don't have answer for you, but I keep mine at 42 and last week one was low and the warning light came one. I didn't think it was that low, it was something like 38-39 cold when the light came on, but judging from that, I think if the computer thinks 39 is low, that 42 aint that far away from being a bit low too... Ahhh I don't freakin know... I think I will go by fyr145's advice and go in the middle somewhere...
