I have a Farm Innovators Pro Series Digital Incubator model 4250. The heating element went out. I couldn’t find a replacement heating element so I bought the heating element to a Little Giant 7300. I attached the heating element to the incubator. I successfully wired the fan to the control panel of the 4250. I have the other 2 black and white wires attached to the control panel but it is not getting any power to the heating part of the new heating element. Any suggestions?
