I got a used Hova Bator Modle 1602N incubator with the turner then ordered a new turbo fan for it. When I ordered it they said that this fan will work with my incubator. My DH put the fan on like he though he was supost to but the fan does not cut off when the heating element goes off. Can we fix this or will it keep the eggs from hatching? Burn something up or something else that would not be good for the eggs and or our safety?
